  • Publication number: 20240276120
    Abstract: To improve the image quality in a solid-state imaging element that performs CDS processing. The solid-state imaging element includes an amplitude detection unit and a black spot prevention unit. The amplitude detection unit detects whether an output voltage that is a voltage of a vertical signal line for transmitting either a reset level at which a pixel is initialized or a signal level corresponding to an amount of light exceeds a predetermined determination threshold. The black spot prevention unit controls, when the output voltage exceeds the determination threshold, a first digital signal obtained by converting the reset level and a second digital signal obtained by converting the signal level to different values.
