Solid-state image pickup apparatus, control circuit, and control method of solid-state image pickup device |
摘要 |
In a solid-state image pickup apparatus, a level adjustment control circuit sequentially executes a first level adjustment performing a level adjustment of a pickup image signal based on an electronic iris control signal for changing an exposure period in a solid-state image pickup device according to a luminance level of the pickup image signal, a second level adjustment performing the level adjustment of the pickup image signal based on a gain control signal for controlling a gain of a gain variable amplifier amplifying the luminance level of the pickup image signal, and a third level adjustment based on the electronic iris control signal to lengthen the exposure period to be longer than that of the first level adjustment in a second luminance level which is lower than a first luminance level of the pickup image signal and does not continue to the first luminance level.
