Patent ID: 8830366

Claim:
A control method of an apparatus, the apparatus comprising: pixels arranged in the form of a matrix, each pixel including a photoelectric conversion part, a charge storage part, a charge discharging part, a transfer part, an amplifier part, and a reset part; and a shutter part configured to control an amount of light incident on the photoelectric conversion part; the method comprising switching a driving mode between a first mode and a second mode, wherein, in the first mode, an exposure period is set such that the photoelectric conversion part and the charge storage part are released from a reset state for all pixels included in an image acquisition area to start the exposure period, and, a charge generated in the photoelectric conversion part is transferred to the charge storage part and a charge generated in the photoelectric conversion part after the transferring operation discharged to the charge discharging part to terminate the exposure period, wherein, in the second mode, the exposure period is set such that the shutter part is opened to start the exposure period and, the shutter part is closed after the opening operation to terminate the exposure period.
