← ScienceWhich failure occurs when CMOS image sensor photodiodes saturate?
A)Blooming overwhelms vertical charge transfer✓
B)Dark current obscures weak signals
C)Thermal noise induces pixel corruption
D)Bayer filter generates color artifacts
💡 Explanation
Blooming occurs because excessive charge overwhelms the potential well; the excess charge spills into adjacent pixels via carrier diffusion. Therefore charge bleeds, rather than dark current which affects low-light scenes; other sources create noise.
