[Phenomena specific to CMOS sensor]
Defective pixels
A CMOS image sensor is composed of photo sensor pixels in a square grid array. Due to
the characteristics of CMOS image sensors, over- or under-driving of the pixels results in
temporary white or black areas (as if these are noises) appearing on the screen. This
phenomenon, which is not a defect is exacerbated under higher temperatures and long
exposure time.
Image shading
The brightness of the upper part of the screen may be different from that of the lower part. Note
that this is a characteristic of a CMOS image sensor and is not a fault.
