An object of this invention is to realize high-precision exposure control while maintaining a short time lag until actual exposure processing is executed after an operation input for the start of image sensing processing. To achieve this object, an exposure control value for executing proper exposure control is calculated by an exposure calculation unit upon reception of an image sensing processing preparation start instruction. Exposure is controlled on the basis of the exposure control value calculated by the exposure calculation unit, and an image is sensed. Whether the exposure calculation unit calculates an exposure control value before an image sensing processing start instruction is received upon reception of the image sensing processing preparation start instruction is determined. If no exposure control value is determined to have been calculated, the luminance level of image information of the image is corrected.
