Abstract:
An image processing device for converting an input image signal exhibiting one of interlace and progressive scan format into an output image signal exhibiting the other of said interlace and progressive scan format, with the output image having an output size represented by a number of lines and/or a number of pixels in each line, equal to or different from an input image size represented by the number of lines and/or the number of pixels in each line of the input image, comprising:means for detecting format conversion of the input image signal format to the output image signal format and for detecting size conversion of the input image size to the output image size; supply means for supplying one of plural predetermined initial values in response to the detected format and size conversion; coefficient generating means for generating a vertical interpolating coefficient whose value is dependent upon said predetermined initial value supplied by said supply means; and interpolating means for multiplying pixel data of said input image by the generated coefficient to produce output image pixel data.
