摘要:
The present invention relates to an image processing apparatus and method enabling to correct for camera shake given in image capturing, a recording medium, and a program. Discrete data pieces indicating shifts are obtained. The discrete data pieces are interpolated to obtain data indicating a shift every line. By the interpolation, a correction is calculated every line on the basis of the corresponding shift. On the basis of the corrections, pixel data read positions are determined. Pixel data is read based on the determined read positions. When a pixel to be read overlaps two pixels, pixel data of the pixel to be read is produced (interpolated) from pixel data pieces. In this manner, the effects of camera shake are corrected. The present invention is applicable to video cameras.
