DEPTH CAM as NORMAL CAM. Can we use this for 3D picture/video? - Xiaomi Redmi Note 5 Pro Questions & Answers

Someone found a way to use depth cam as normal cam that took 13mp image https://forum.xda-developers.com/re...miui-stock-camera-portrait-mode-dual-t3816069
now, can we use this knowledge to create or mod a camera app to take 3d picture/video?
theoretically, the easiest way should be simply allowing both camera to take photo / record video simultaneously. This will allow very easy post on a computer to merge them into one 3d picture or 3d video.
or as a workaround, maybe.. simply open https://forum.xda-developers.com/re...miui-stock-camera-portrait-mode-dual-t3816069 AND google camera on split-view, and initiate recording/take a pic?
i cant test it as im still waiting 100 hours left for unlock.
thankyou

It's no use because of interpolation. Our depth cam is 5MPx, so if there is a real way to shat 3D pictures they will be half-blured because the 5mpx picture will be expanded to match 13mpx.

the reverse should work then, 13mpx scaled to 5mpx

[Q] Arc very weak zoom

hello
Is there any way to improve the camera's zoom?
it can improve a rom?
photos are very nice but the zoom is not clear and very weak
B.R.
Dont think there is a way to do that. If you want good zoom probaly better off with a actual camera

The short answer is no. Your phones camera, like most smartphone cameras only has digital zoom. This is essentially the same as cropping an image using photoshop or some other photo editing software.
If you want to be able to zoom and have crisp photos, the only option is to buy a camera with OPTICAL zoom.
As a rule I have found you are much better off ignoring zoom on your camera completely, and editing it later on, and if you do use the digital zoom feature, use as little magnification as possible.
Any software updates/changes could the algorithm slightly, and in my opinion, it rarely makes much difference, and being Sony has a digital camera/SLR arm (they also bought Minolta a while back), I would suspect they have tweaked for quality already.
I ask because I previously used the desire hd and there was a very good zoom

DHD camera is not as good as arc in the first place, and the zooming function make it worse..
I had a DHD with 2.3.4 rom and zoom was very good and clear
Take the photo and zoom afterwards with a pc or an app if zhe zoom of the cam isn't good enough for you.
Arc has the BEST camera on a mobile phone...

Well, the .181 on 2M and 4M has good zoom

I agree that digital zoom is not as good as optical but it has its used on the Xperia ARC. You will actually get me details zooming in than taking a full size picture which you enlarge later on.
Try the following to test this, it will only work on motives close by. Place a book 1-2 meters away from you. Take a full size picture and then take a one where you zoom in on the book. You will actually be able to read the text on the book on the zoomed picture while the enlarged full size picture will show the book as pixelated and it is difficult to read the text.
There is no difference on motives far away between the zoomed picture and enlarged full picture.
I am not sure why the objects close by contain more details when zooming than enlarging a full picture. My best guess would be that SE has some logic buildin on the photo chip that on the zoomed picture correlate pixel readings on the sensor and not just cropping and enlarging the final picture.
Please let me know if you experience the same, I am very puzzled that the zoomed picture for objectives close to the camera contain more details than the full size picture.

Nexus Camera, no widescreen/16:9 photos??

Lets put ugly black bars on the sides of all your pictures while giving you gorgeous 1080 video capture.. Okay seriously, any chance the stock camera apk can be modified to allow widescreen photo capture?
Software...limitations....for...NOW...hopefully Google will bump us up.

You mean instead of taking full 5mp photos, you want the camera app to crop the top and bottom of the photo and downscale it to 2mp? Because thats what 1080p is.
When viewing a picture on a Widescreen monitor, an HDTV or our phone's screen for that matter, 16:9 just looks better.
Anyone know if this is on the to do list, or if there is a way to do enable this on the stock camera app?
Surprised the camera doesn't default to 16:9. Most phone cameras haven't used 4:3 in a long time.
zoom in on the photo if you're bothered, I'd rather have full resolution and make full use of the 4:3 chip inside than having some cropped off.
It's as bad as the people who moan when DVDs, Blu-rays and film channels (at least here in the UK) show films properly which means there's black bars at the top and the bottom, I'd rather see the whole thing that have some edges chopped off!
Whats also interesting is if you take a picture while recording a video in 1080p or 720p for that matter, then those shots are in widescreen.
Forget which quality is better for a second and think about the fact that this will lead to having different aspect ratios for some of your pictures since theres no way to force is on the Camera shots.
I dont know whether the quality is better with widescreen or not (it sounds like not) but I think we can all agree we'd rather have the option to turn it on or off.
Hopefully it comes in an upgrade or MOD at some point.
Has anyone tried using Vignette?
Yes, Vignette seems to work well on ICS. That said, I haven't found a way to make it shoot 16:9 stills. However, it looks like Camera360 Ultimate might -- and for whatever reason, it is free in the Market as I type this.

Yeah guys, VIGNETTE works well on SGN, you ca adjust aspect ratio to 16:9.
I have just purchased this and need to try how is the quality now...
but at least it works in wide screen mode, even though the effect is more or less a zomed in pictures, but the app can save simultaneously the original 4:3 photo as well. . It would be better to have a native 16:9 camera..
cheers

What ROM are you using and what settings in Vignette to get it working? On my SGN it won't even refocus, it crashes as soon as I touch the screen and I get this message:
VIE encountered an error.
Runtime error: java.lang.
UnsupportedOperationException
I sent the dev an email ages ago but haven't received a response.
I've tried rebooting, un-installing, re-installing, full wipe, turning force GPU rendering both on and off and nothing seems to work :,(

Most camera-chips and camera's are 4:3, including on high-end DSLRs.
If you want it to have a widescreen look, either zoom in or just crop it. It's not that hard.

Yeah, and this is limitation for capturing normal widescreen photos. For example, my previous xperia neo has 8M camera and it native sensor has 4:3 (3264*2448) or total ~8 million pixels. But it software camera has 16:9 mode which crop top and bottom lines for 16:9 (3264*1839) or total ~6 million pixels. At the end, our gnex camera has 4:3 (2592*1944) or ~5 million pixels. For cropping this to 16:9 we'll have only 1458 for height. This is totally loss information for such a sensors.
If your such a camera nazi then crop the pics to 16:9. But i agree with the people that say why downgrade quality , im sure if they did you would start a thread on nexus camera not detailed photos

It's actually 3:2. Only Olympus produces 4:3 DSLRs.
Back to the main topic, if you want to capture somewhat widescreen images OP, try Camera ICS.
It doesn't do 16:9 but 3:2, at least. It also offers various improvement.

No, it's 4:3 but there's a setting in Camera ICS that automatically crops 4:3 images to 3:2.
By doing so, you lost about 0.5mp (from 5.0to 4.5mp) which isn't a big deal.
---------- Post added at 11:27 AM ---------- Previous post was at 11:16 AM ----------
And guess what? Camera ICS also supports 16:9 (3.8mp) format.
Camera Mx, 16:9 aspect ratio
Camer JB +
Install Camera JB+ from the app store. It gives the option of Widescreen (16:9) pictures but you have to compromise with MP (3.8MP)

Compressed Photos

Has anyone else noticed the file size for photos taken on the one x? My Photo's taken at full resolution are only coming in at circa 1.8mb - seems rather small often images at the same resolution we're double the size on my DHD.
I use Camera ZOOM FX, much better app than the stock, it also not as aggressive with compression in post processing.
P.S. Just did a quick test, photo taken in Camera Zoom FX (2.7mb) is twice the size of photo in stock camera app (1.4mb).

I think we lose the cool features of the stock app such as the burst mode and the recording video and taking pictures
You can also have more than one camera app. Stock for burst mode, one for taking lower compression photo and another for social media.
Edit: just tried burst mode in the camera zoom app, and it is faster the stock! You can take up to 32 photos in one burst around 8 sec!
It looks like the app uses video recording for the duration of the burst and process the photos afterword. It is an interesting way of doing burst mode.

Good point Or I can hope the DEVs can fix the high compression rate. Some Useful Data must be getting lost

[Q] Photo effect ..

Just wondering can anyone tell me when you can actually use the photo effect?? I have noticed there are times when I took shots, I cant use the duo effect editing???

Ah.....I think I found my answers after googling around.....Here is the answers if anyone is interested:
There are a number of reasons why Duo Effects may not work with your photo:
One or both lens were blocked when you took the photo.
You didn't use the Camera capture mode. You can't use Duo Effects on photos taken in other capture modes.
The photo you're trying to apply the effects to was taken using the front camera.
The scene was not set to Auto.
The flash was not set to off when the photo was taken.
There was not enough ambient light when the photo was taken.
You've zoomed in or the camera may be too close to the subject when the shot was taken.
Duo Effects can't be applied to cropped photos.
Duo Effects can't be applied to the same photo more than once.
Duo modi all the time greyed out
Hi,
i have the same problem all the time the camera says lenses are blocked. But my hand is far away form the two lenses

Ok but, anyway, is 20mpx camera exploited by gcam to get better photo in some way or only the 16mpx cam is used in every situation so 20mpx is never "powered on"?

In OOS 20MP camera is used only in auto mode and portrait to detect depth. It shoots 20MP photo then magic OP software interpolate it to lower res to "improve quality and decrease noise" and then i don't know why, extrapolates that image back to 20MP. If i'm right it is written in camera HAL so we can't do nothing with it... Test it by Yourself, just type *#*#1597#*#* in dialer and take photo with "tele" and "wide" in sunny day.
I'm not sure 100% about it, correct me if i'm wrong.

Dialer? Why using dialer to take photo?
@rmroot You use dialer to input this code I wrote earlier. It opens camera app which now allows You to switch lenses manually.
