Patent ID: 7782377

Claim:
An image sensing apparatus comprising: a plurality of pixels arrayed in a horizontal and a vertical direction; a storage unit configured to store a plurality of one-dimensional correction data in a horizontal direction in accordance with a plurality of ISO (International Organization for Standardization) sensitivity settings; a setting unit configured to set ISO (International Organization for Standardization) sensitivity; a calculating unit configured to generate two-dimensional correction data by expanding the one-dimensional correction data in a vertical direction, which is stored in the storage unit; a correction unit configured to correct image data outputted from the plurality of pixels by using the two-dimensional correction data generated by the calculating unit; and a control unit configured to read the one-dimensional correction data in the horizontal direction from the storage unit in accordance with the ISO (International Organization for Standardization) sensitivity set by the setting unit, and control the calculating unit so as to generate the two-dimensional correction data by expanding the read one-dimensional correction data in the vertical direction.
