Lag in the Xperia Camera while taking Pictures.

Hi,
I have used different roms, including the orignal one, i always face the problelm with the camera, when i press the camrea button to take the snap, it capture the photo after 2,3 seconds, and in that time, (pplz have moved, and its always blurr), how i can remove this Lag time for the camera, so it take the photo shot, as soon i press the camera button.
this is really irritating and annoying, Hope to get some true solution to it.
Regards
Jade

There is a quick fix to the lag. Go to focus options and choose the infinite one!

I tried via this way many time, but still facing lag problem while taking the pictures, the snap shot is taken after 1-2 seconds of pressing the camera key.
Is there any repair, or fix CAB for it , or some other solution.
Regards
Jade

General Tip
the easy way is to use sport mode (i made it the default scene mode). however you will always not like the color it get, but acceptable in bright light condition. Next, i set the focus to infinite, manual white balance. The rest will depend on your phone software/system configuration.
if you are willing/knowlege enough, i suggest to change the system cache (cache,repl,gdi,fat entry cache,block transfer) just big/small enough for your need. Too small = sluggish respond, too large = may unstable the phone, data lost/corrupt, random lockups.
Oh, do try the xperia x2 vga driver and sdcard tuneup if you haven't already.

Try HKLM/Software/HTC/Camera/Captparam and set CapKeyDelayTime to 0.

That's the one! Or use Xperia Tweak, and look for shutter delay in the camera section, if you don't want to edit the registry directly yourself.

does anybody have this problems with x1 camera..... the result of the picture is darker when you transfer it to a pc or upload it.... its only show the true color on the xperia image preview, when actually its too dark... any one ???

I just didn't find such entry in the X1 registry. Should I add one or whatever wrong with my machine?

Hi Paul,
Xperia Tweak 2.0 doesn't have the said camera section. May be a new version available, where can I get it? Thanks in advance for your advice.

oops, sorry... the option is in Advanced Config (I confuse the two applications, Advanced Config is much more comprehensive)

htc camera
sorry mate. that parameter does not exist on stock rom. unless it's already cooked or you install it yourself. and it's for htc cam app(which i think the iso speed option did not work. like i want 400, it capture in 201), not experia default one.

to uhuy*
you got it all wrong. your handheld/camera/phone lcd display will never show the true color/contrast/etc output of the recorded image. they are very limited in everything and tend to trick your (inexperience) mind about how good/bad things are. think, winmo only output 65k(16bit) color. doesn't matter if your screen got 200 thousand+ or 16m color display screen. it's capped that way. what you're seeing have been through interpolation, resampling, device enhancement, bla..bla..bla. the real thing is on your desktop monitor(assuming it's decent and you didn't mess it up). gamma too low perhaps?

is your monitor calibrated?

Expert Opinion?
I'm facing the same problem with Xperia X1 camera lagging, and blurry...
I'm using the default Xperia cam software.
Any expert care to provide a comprehensive solution to this problem?

Only fix : Sports mode + Infinite focus.

[MOD] Fix screen warm tint

Hello,
I've been really angry about screen of SGS II - especially about its warm color tint. Today I've been playing with MDNIE profiles and finally managed, how to get off that annoying tint.
Attached file modifies MDNIE settings for "Standard" mode in "Settings > Display > Screen mode" options.
To apply this patch, EXTRACT ZIP and replace extracted "mdnie_tune_ui_standard_mode" with one in your "/system/etc" (root needed).
NOTE: This is not an CWM UPDATE.ZIP !!!
Try it and give me your suggestions!
Thanks!
EDIT:
If you want blueish Dynamic mode, just rename attached "mdnie_tune_ui_standard_mode" to "mdnie_tune_ui_dynamic_mode" and overwrite with one in your "/system/etc".
Settings are same but Samsung have "something" else added in Dynamic profile option.
Added comparison pictures - thanks to bala_gamer!
Note: Real look is bit different than on the pictures (the display is not that blue - at least on my screen). Pictures just shows how big amount of change this is.
There are a lot of screen types so you have to test in on your own if will it look acceptable to you

Just tested it and it did made a difference. Isn't the bluish tint a little too much?

I think that its just a matter of manner.
If I compare these settings with my old, perfect, SGS 1's display, it is still too warm...

It's going to be difficult to match the SGS1 because Supercurio implemented his Voodoo Color application. However, I think your fix is pretty good. Still a little off but much better than before. Thanks

Nice find, I quite like the change, looks to be a little further down the blue side of the spectrum on mine than neutral-white.

I do not use Voodoo color at my SGS 1 at all - everything is in default about screen. I think that through these MDNIE settings we can make SGS 2 display colors almost perfect! It just need time to play with...

I think it's a matter of taste. Plus, I think not all SGS2s are calibrated the same way. For me, I like the colors the way they are except for the highlights which I think are on the cold side; need more red and a bit of green.
Anyway, good job. Keep it up.

Could someone show some comparison pictures?
Would be nice to see.

I have access to four another SGS2 (in company where I work) and all of them are grossy warm...I've applied my settings to all of them and they are looking much better.
I've tried to take a photo with and without mod but I have camera with auto white balance so there is no difference. The change is not very significant either...just a little change of color tone - better to try yourself but don't forget to backup your original files

still not fixed
The color is still very yellow compared to the galaxy (I9000), but thanks for your temporary fix.

I like it, Difference is vivid..

Super! !!! Thanks man!

This is amazing!
Permission to include in future releases of DlevROM2?
Again awesome stuff here! Keep it up, really makes a difference

Thanks a lot !

I have a more bluesh tint by default on my SGS2 as well. So I guess this fix wont do any good to my color profile. I guess it should be more warm ... more red and green probably...

thanks for your work, but can not find a mdnie_tune_ui_standard_mode file in /system/etc.
I´m on cm7. Is it missing there? How can your patch be applied there or is it just not necessary?
Thanks

On Cyanogen !!
You don't need to do this....Cyanogen is PERFECT !

I think it is a bit too much blueish, however, the yellowish is still there. By the way, thank you very much for this, I hope you could improve it to be perfect

Nice. Too blueish for my taste though

[DEV] RGB ambient light sensor test app (no root required)

Hi all,
As some of you may know, the I9300 has an RGB ambient light sensor. I made a little app to show off the capabilities of the sensor. It's very basic at the moment since I just finished it but I though I'd share it with you guys and gals before heading to bed.
The sensor in the phone reports raw values, which haven't been adjusted to take into account the different sensitivity the human eye has to different colours. The app compensates a bit, by scaling the raw sensor values according to the CIE response curve. However I have not yet taken the non-linearity of intensity into account.
At the moment the app works best for strong colours.
To use the app:
Launch.
Done.
On the top left are the values reported by the sensor. The bottom square shows the colour after scaling/processing. If you tap the coloured square you can pause/unpause the measurement.
The attached pictures are what I get when I test my monitor. If I hold the phone next to the screen they look almost identical. So I can conclude my laptop screen is ****e
I have only tested this on the international version. So all you US folks, feel free to try it and let me know if it works.
-rcblob

Very nice work, seems like more and more people are learning to dev.

Very raw app, but with some work this could be useful.
Ps. Settings doesn't work

Thanks for the support.
I'm stuck on what to actually do with this, so if anyone has any ideas/features feel free to throw them out there.

Very nice! I'm just thinking that is there anyway we could turn this to an pc monitor calibration tool. Is the sensor accurate enough? Just thinking of the possibilities...

Nice app, i never knowed, that there are an rgb sensor)
Will be very cool if someone make something usefull with that)
Thank you for the show possibilities
Cheers

This could be an awesome app for people who want to 'Colour Pick' from swatches, Eg: Paint matching, fabric matching etc...
You could also refine this to tweak & calibrate monitors (LCD/Plasma) just like thos $200.00 sensors you can buy at Photo stores.
For us photographers and cinematographers out there, it could be refined further to become an incident light meter...
Could also be used within a game where sensed colours could match a result of some kind..... endless possibilities..
Anyway, This is a very cool app indeed! I cant stop playing with it, Thanks for this!

[Q] Camera exposure settings

I have consistent problem with camera while taking shots during shows/concerts. Take a look at the pic, the normal looking one at the top is actually under exposed -2. The bottom is exposure 0. I have the same problem while taking videos. For some reason Samsung gets very sensitive while there is a big differential in the light settings. My friend's LG HD and all iPhones don't have this glare.
Is there a place I can edit and modify exposure settings? I'm on TW Jedi X12, but found all TW roms have that 'problem.'

C'mon, no one has the answer to this basic question/problem?

Hi. I don't know where to edit exposure but, have you tried Camera FV-5? It's a really neat app, and it does a real job. You can adjust the exposure, ISO, shutter controls, white balance, metering and it also display a live histogram while focusing. DSLR controls on your Note2.
Hope it helps!

Thanks for the tip. Great app indeed but no video option. Will be looking to find how to edit the camera app file and make exposure -2 to stick as default.

Do you have auto contrast on? Seems like that may be worth looking into

LOL - it was a smali edit that fixed it. I am away from my laptop so I can't tell you the specifics at the moment, but there is one particular smali file that sets the defaults for a number of things - including exposure value. There were a few places where the exposurevalue:I and camcorderexposurevalue:I were set to 0x0 (i.e. 0 on the exposure setting). Each integer seemed to be equivalent to a half step on that scale (so 0x1 would be an exposure of 0.5, etc.), so where those values were being set I changed them to -0x4 (or -2). If folks are interested I could post just the modified camera apk, and dkb218 if you want the super-specifics shoot me a PM and I'll go into some more detail once I have the files in front of me (this is all being said from memory, which in my case is rather fallible lol).

Post the modded camera.apk when possible and thank you

camera exposure settings
Is there a way to get the exposure value to go lower than -2? I'm trying to take pictures of powerpoint presentations. The Ipads in the audiences are having no problem with tapping on the screen, the camera focuses on the powerpoint slide and it is clearly visible. The Note 8 still whites it out. An exposure of -2 helps but not enough.

Question Pixel 6 Pro gcam mod?

Whilst this may initially seem pointless, given we have the Pixel gcam of course, has anyone found/tried any gcam mods for our device? The reason I ask is I'd maybe be interested in adjusting some of the saturation/sharpness levels saved as a profile, to suit my personal preferences

I haven't seen any yet. I'm sure there will be in time.

I'm very keen on seeing this as well. Especially the ability to turn down sharpening and noise reduction (so that it can be done more elegantly in post).

If you are planning to go post, why not use the DNGs in the first place? They offer way more room for adjustment.
The main use I peronally got from the modded GCAM on my Pixel 3, was to get better JPEGs out of the box that retain the level of detail and natural sharpness off the DNGs. I so hope to be able to do this for my 6 soon. The DNGs are AWESOME, but the JPEGs are just weak.

I experimented a bit (since the new P6 GCam is oversaturating/HDR-ing the s*it out of every picture), and people had some discussion about this in the P6 Dev group - summary: Nope, previous mods/versions don't work properly, just sideloading them doesn't give good results.
We'll have to wait for "decent" custom GCam mods that are tuned for the P6. As far as I know, there are none (yet).

Well, by "post" I sometimes just mean sharpening a bit in Snapseed or Instagram; and adjusting levels. I like to set the jpegs to be slightly soft, with a bit more noise than most find acceptable, and with lower contrast. Frankly, once I had the modded GCam set up correctly, the 3XL did a great job with the rest of the parameters. You have to do a *lot* of work on a DNG just to bring it up to the level of Pixel's computational processing (once you've dialled down the overprocessing). After which, yeah, you have a 16-bit image with much more latitude, but that's not generally how I use my phone.
I try to do critical work with larger cameras. And on anything larger than a phone, I never shoot jpegs — only raw. Although even that may change if the big camera makers start getting serious about computational photography; Olympus is making noises in that direction. I'm old school, when it comes to working with unprocessed files, but there's a lot to be said for relying on the latest cameras' computational wizardry.
Anyway, I sense that we basically agree here.

Hmm ... I find, that mostly dialing down lighting and highlights as well as pushing saturation and vibrancy by about 10-20 in Lightroom mostly brings Pixel DNGs to a reasonable base, where editing them is not more work than touching up the JPEGs - albeit with much more latitude for edits. But I get, that everyone has their own workflow and baselines.
I just am glad, that we have these possibilities at all

Glad you found it. If you set your camera app to also take the RAW files, you can find them in the pictures -> RAW folder on your phone. Try it, it really is worth it. They look not that nice at the beginning. But turn down lighting and highlights a bit, push up saturation and vibrancy a notch and you will see, that the details are WAY better.
Free tools to do that on your device are Snapseed and Lightroom.

This mod works pretty good with p6p:
https://www.celsoazevedo.com/files/android/google-camera/dev-MWP/
in Mod Settings -> Developer Settings : untick "segmenter_use_darwinn_tpu_delegate" to avoid app crash whenever you shoot a face.
out of this small but fixable bug, with this mods default settings, there are a lot more details vs the stock google camera app.
As always, more details = a bit more noise.
But noise is not a big problem when it's controlled, especially if you make prints.
The xhdr processing in settings increase the dynamic range further too.
Everything can be adjusted in the settings, this mod deserve to be known.
