Patent ID: 8593549

Claim:
An image capture apparatus comprising: an image sensor which photoelectrically converts an object image; determination unit configured to determine one image capturing mode from a plurality of image capturing modes; driving unit configured to drive said image sensor by different driving methods in the respective image capturing modes determined by said determination unit; and control unit configured to control operation of said driving unit, wherein said image sensor includes a plurality of two-dimensionally arrayed pixels, a plurality of column output lines, and a plurality of holding units which hold pixel signals output from the plurality of pixels via the column output lines, and said control unit drives said image sensor in a first power save mode in a case that a horizontal transfer period in which pixel signals stored in the holding units are sequentially output outside said image sensor is not less than twice a vertical transfer period in which pixel signals from pixels are held in the holding units via the column output lines, and drives said image sensor in a second power save mode in a case that the vertical transfer period is not less than twice the horizontal transfer period.
