An photographing apparatus (300) including: an image sensor (310) that includes a plurality of pixels. The apparatus is configured to perform a first readout on charges stored in a group of pixels among the plurality of pixels at a first readout time and perform a second readout on charges stored in the plurality of pixels, including the group of pixels, at a second readout time An image processor (320) is configured to detect a pixel in which a light leakage has occurred of among the plurality of pixels. This is done based on at least one of a value the first readout charges and a value of the second read out charges, and perform a correction on the detected pixel to generate an image.
