An image sensing apparatus comprises an image sensor configured to convert an optical image of a subject into image signals by photoelectric conversion. The image sensing apparatus acquires information for estimating a magnitude of a dark current in the image sensor, and, on the basis of the acquired information, selects any one of vertical linear noise correction processing, black subtraction processing, and normal readout processing in which neither the vertical linear noise correction processing or the black subtraction processing is carried out. Then, the image sensing apparatus carries out the vertical linear noise correction processing to correct a vertical linear noise in an image if the vertical linear noise correction processing is selected, or the black subtraction processing to correct a vertical linear noise and a fixed pattern noise in an image if the black subtraction processing is selected.

A device and a method for reducing a smear effect. The device comprises an image sensing module and a smear reduction module. The image sensing module captures an image and optical black data generated from the optical area of the image sensing module. The smear reduction module searches the optical black data generated in the lower boundary of the optical black area corresponding to which generated in the upper boundary of the optical black area according to coordinates of the optical black data. Thereby, the smear reduction module can compute an offset line representing an offset of the optical black data, and the smear reduction module compensates the smear effect occurring in the image.
