Camera Widget: Auto-accept capture image

Question

I want to capture data matrix label since data matrix scanning not available in Hololens II. Then, OCR will read the data matrix value. Example as picture below:

So, below is sequence of how camera widget work in Hololens II.
1. 3 seconds countdown2. Camera sound3. Image preview with cancel, retake accept button
 
But in this case, there's a delay around 2~3 seconds between 2. Camera sound and 3. Image preview.
Is it possible to customize camera widget to eliminate :
1. delay 2. cancel, retake and accept button

I would like the camera to auto-accept image like usual camera work which image automatically taken on user click shutter.
 
Thank you.

unfortunately, it's not available in the hololens yet.

i dont control the priority queues unfortunately but i've prompted the PM team to take a look.

as for ios etc., here's some code you can try out -

1. create a text widget (called "text")and a3d image called "photocapture"

2. add the javascript below

3. link a button 'click ' even to the '$scope.screenshot' (or screenshotNo3D).

4. run the experience; each time you click the button, you'll get an immediate (ish) response and the image will show in the experience.

obviously you dont need the text or image widgets - they are just here to demonstrate.

var callback = function (pngBase64String, args) {
$scope.view.wdg.photocapture.src='data&colon;image/png;base64,' + pngBase64String;
$scope.view.wdg.text.text = args;
$scope.$applyAsync();
};

// params = { dataURL:bool, withAugmentation: bool, imgFormat: string, imgWidth: number, imgHeight:number}
$scope.screenShot = function() {
var params = {withAugmentation: true};
tml3dRenderer.takeScreenshot(params, callback, null);
}

$scope.screenShotNo3D = function() {
var params = {withAugmentation: false};
tml3dRenderer.takeScreenshot(params, callback, null);

}

happy snapping.

For IOS/Android devices, the way around this is to use th underlying API to capture images; this way tyou can sidestep the UI and the accept etc. buttons.

This request has recently been made to support the same capability on the hololens. Hopefully this enhancement will be addressed quite quickly.
