screen is getting stuck while saving the image and it is taking 40 to 50 seconds to display the saving image.

camera.js:

        let video = document.getElementById(src);
        let canvas = document.getElementById(dest);

            ctx.drawImage(video, 0, 0, canvas.width, canvas.height);

            let dataUrl = canvas.toDataURL("image/png");
            const base64ImageSize = Math.round((dataUrl.length * 3) / 4);

            await dotnetHelper.invokeMethodAsync('ProcessImage', dataUrl, base64ImageSize);
        } else {
            console.error('Video or canvas element not found.');
            throw new Error('Video or canvas element not found.');
        }
    } catch (error) {
        console.error('Error capturing frame:', error);
        throw error;
    } finally {
        hideLoadingSpinner();
    }
}

the image quality is good but while processing image it is taking so much time and also screen is getting stuck.

how to display the image immediately with good quality after clicking the save button.
