🐛 photoResolution: 'max' not the same as native camera photo. about react-native-vision-camera HOT 9 CLOSED

3.9.2 (v4)

Well, what is it? I'm assuming V4 then?

So I just ran this on my iPhone 15 Pro:

const f = useCameraFormat(device, [{ photoResolution: 'max' }])
console.log(JSON.stringify(f))

And I get

{
  "minISO": 55,
  "photoHeight": 6048,
  "fieldOfView": 71.28567504882812,
  "videoHeight": 3024,
  "autoFocusSystem": "phase-detection",
  "supportsVideoHdr": false,
  "pixelFormats": [
    "yuv",
    "yuv",
    "rgb",
    "unknown",
    "yuv",
    "unknown",
    "yuv",
    "unknown",
    "rgb"
  ],
  "videoStabilizationModes": [
    "auto",
    "off"
  ],
  "videoWidth": 4032,
  "minFps": 1,
  "supportsPhotoHdr": false,
  "photoWidth": 8064,
  "supportsDepthCapture": false,
  "maxISO": 12320,
  "maxFps": 30
}

..which is 8064x6048, the maximum available photo resolution.

I think the problem you're seeing is because you are using the wrong device, not all devices have the same formats. See the "Camera Devices" documentation for more information.

Maybe you need to select the triple camera:

const device = useCameraDevice('back', {
  physicalDevices: ['ultra-wide-angle-camera', 'wide-angle-camera', 'telephoto-camera']
})

..as those devices use multiple devices to deliver photos that are stitched together - hence the higher resolution.

hi,

Thank you for your help. So, I've experimented with the different physical devices ('ultra-wide-angle-camera', 'wide-angle-camera', 'telephoto-camera' and various multi-cam configurations. Still can't seem to capture pictures that are of the same high-resolution as a native device's camera. Here's a brief breakdown:

Using an iPhone 15 pro max, the example app in 'react-native-vision-camera iOS example', the result is: 8MP, 2160x3840
Using an iPhone 15 pro max, my react-native-vision-camera app and
const device = useCameraDevice('back', {
physicalDevices: ['wide-angle-camera']
});
the result is: 12MP, 3024 x 4032

Using an iPhone 15 pro max, my react-native-vision-camera app and
const device = useCameraDevice('back', {
physicalDevices: ['ultra-wide-angle-camera', 'telephoto-camera']
});
the result is: 12MP, 3024 x 4032

Using an iPhone 15 pro max, my react-native-vision-camera app and
const device = useCameraDevice('back', {
physicalDevices: ['ultra-wide-angle-camera', 'wide-angle-camera', 'telephoto-camera']
});
the result is: 12MP, 3024x4032

Using an iPhone 15 pro max, my react-native-vision-camera app and
const device = useCameraDevice('back', {
physicalDevices: ['ultra-wide-angle-camera', 'wide-angle-camera']
});
the result is: 12MP, 3024x4032

Using the iPhone 15 pro max's camera:
the result is: 24MP, 5712 x 4284

[The scene was exactly the same for all of the above picture taking]

So, the question is, how can I configure react-native-vision-camera to use the same high-resolution as the default camera (i.e, 24MP, 5712 x 4284)?

Thank you so much for your help

kind regards

I think the default Camera shoots ProRAW or HEIF or something where it can do higher resolution. VisionCamera doesn't have support for that yet (see #1851)

from react-native-vision-camera.

Would you happen to know when "react-native-vision-camera" will support RAW and Apple ProRAW Formats?

As mentioned in the issue I linked, it is currently a feature request I'm raising money for (to fund the development) - I don't plan on developing this for free in my free time

from react-native-vision-camera.

Could you explain how the process works, please?

from react-native-vision-camera.

People donate some funds, and once the pool is full I will implement it.

from react-native-vision-camera.

how long does it generally take for the funds to reach the appropriate level? how long will it take to implement the feature? what if more funds are needed (ie., it is more complex than originally assessed)?

from react-native-vision-camera.

I don't know, I don't have a lot of experience with that.
But generally people don't like paying money for open source, so it's hard to raise funds.

If it takes longer, no more money will be requested, that's my risk.
