    • A signal processing apparatus which is capable of performing a smear amount correction processing suitably according to change in the smear amount to suppress overcorrection of the smear amount. An output value of an image sensor and a smear amount on each of vertical lines of the image sensor are stored, respectively. An output signal value of an optical black portion on the image sensor stored in the first memory is compared with the smear amount stored in the second memory to determine a cyclic coefficient based on the comparison result. The smear amount is calculated based on the output signal value of the optical black portion on the image sensor stored in the first memory, the smear amount stored in the second memory, and the cyclic coefficient determined by the smear detection unit. A correction coefficient is calculated based on the smear amount determined by the smear amount calculating unit. The output signal value on an effective pixel portion of the image sensor stored in the first memory is subjected to a correction processing using the correction coefficient determined by the correction coefficient calculating unit.

    • According to this invention, even when an image capturing apparatus has a plurality of read modes, the frame rate can be prevented from decreasing in a high-resolution video photographing mode. The image capturing apparatus includes an image sensor and drive unit. The image sensor includes an effective image sensing area having a plurality of pixels at the center portion of the image sensor, and a light-shielded pixel area having a plurality of light-shielded pixels at the peripheral portion of the image sensor. The drive unit can drive the image sensor in a plurality of modes, and drives the image sensor such that the plurality of read modes are almost equal to the light-shielded pixel read time BL-MIN for reading pixel signals in the light-shielded pixel area.

    • An imaging apparatus includes a control unit which has a first mode in which image signals are read out successively from every predetermined line of a first photoelectric conversion element group arranged in a first region of an imaging plane; and a second mode in which image signals are read out successively from every predetermined line of a second photoelectric conversion element group arranged in a second region which is different from the first region of the imaging plane. In addition, the control unit performs control so as to cause a period from starting readout of the signal of the predetermined line to starting next readout of the signal of the predetermined line in the first mode to be the same as that from starting readout of the signal of the predetermined line to starting next readout of the signal in the second mode.
