The present invention relates to a CMOS image chip, a camera, thereof, and a debugging method thereof. The CMOS image chip of the present invention disposes light emitting diodes in a light emitting region and uses a projection pattern of the light emitting diodes on a substrate to be inspected to determine a photosensitive effective region of the CMOS image chip on the underlay to prevent the issue that the conventional technology uses an image by camera imaging on a display device as debug basis and a camera imaging image has signal delay to result in a low debugging efficiency, which drastically improves a debugging efficiency of the camera.
