In an image sensing apparatus which performs noise reduction processing using pixel signals obtained by consecutively scanning a CCD image sensor at different timings, for performing image expansion in the vertical direction by controlling scanning of the CCD image sensor, an area to be read in the CCD image sensor is set on the basis of an expansion ratio. Pixel signal which have undergone the noise reduction processing and stored in advance in a memory are read so that colors of corresponding pixel signals do not shift. The noise reduction processing is performed on the current pixel signals read from the set area using the pixel signals read from the memory. The noise-reduced pixel signals are stored in the memory, and used in the next noise reduction processing for pixel signals read from the CCD image sensor of the next period.
