Abstract:
An image processing apparatus comprising:a frame memory configured to store image data;a vertical reduction unit configured to reduce a first image represented by the image data in the vertical direction when the image data are written to the frame memory, the vertical reduction unit including:a first detector configured to detect a first line which is to be dropped by the reduction, anda first interpolator configured to interpolate a plurality of lines of the image data including the first line and a second line adjacent to the first line to modify an image portion of the second line while maintaining image data of other lines which are not adjacent to the first line to be dropped by the reduction; anda horizontal reduction unit configured to reduce a second image represented by the image data in the horizontal direction, the horizontal reduction unit including:a second detector configured to detect a first pixel which is to be dropped by the reduction, anda second interpolator configured to interpolate a plurality of pixels of the image data including the first pixel and a second pixel adjacent to the first pixel to modify an image portion of the second pixel while maintaining image data of other pixels which are not adjacent to the first pixel to be dropped by the reduction.
