Abstract:
1. An image capturing apparatus comprising: an image sensor in which a plurality of pixels each having a photoelectric conversion element are arranged in a matrix; a synchronizing signal generation unit configured to generate a short-term vertical synchronizing signal as a vertical synchronizing signal for short-term exposure, and a long-term vertical synchronizing signal for long-term exposure, one cycle of the long-term vertical synchronizing signal being equal to N cycles of the short-term vertical synchronizing signal; and an exposure control unit configured to repeat performing the short-term exposure for the predetermined number of short-term exposure lines of said image sensor according to the generated short-term vertical synchronizing signal and performing the long-term exposure for the predetermined number of long-term exposure lines of said image sensor according to the generated long-term vertical synchronizing signal, wherein said exposure control unit starts a first read operation of pixel signals for the long-term exposure lines in synchronism with the long-term vertical synchronizing signal, and said exposure control unit starts a second read operation of pixel signals for the short-term exposure lines in synchronism with the short-term vertical synchronizing signal, which does not overlap a period of the first read operation.
