That is, the user touches the front app UI, but a user interaction event is transmitted to the underlying app, and the corresponding app is processed by the underlying app. (Overlay of front app UI applied)
- the pixel set at a specific location of the front App UI is processed transparently.
- This pixel set has the image pixel value of the underlying app UI, not the image pixel value of the front app UI. Therefore, if you compare the pixel set between the captured front app UI's previous image and the front app UI's current image, you can see that the underlying app UI image has changed.
- 6 shows a set of transparent pixels of the front app UI (underlining app UI change detection).
- FIG. 8 is a block diagram showing a detailed configuration diagram of the entire logic for processing the captured image.
- the image prime for output may be dropped due to synchronization of the fence signal. This causes an error in the logic for detecting changed source image (underlying app UI), so the pixel value at a specific position in the image prime output to detect the drop image prime over time A unique Magic Code is injected, and the pixel value is checked from the captured image to check whether it is dropped.
