Claim One:
1. An image processing circuit to which interlace image data is supplied and in which the image data is subjected to image processing including time series comparison or spatial data comparison, comprising: I/P conversion means for converting the interlace image data, which has been supplied, to progressive image data; and image processing means for subjecting the image data, which has been subjected to conversion to the progressive data by the I/P conversion means, to image processing, wherein the I/P conversion means creates new data, in each field of the interlace image data, which is used for interpolation so that the number of fields of whole image data does not vary during converting the interlace image data to the progressive image data, and a line to be interpolated by I/P conversion receives data in accordance with calculation using data of at least one line located before and after the line to be interpolated in a sub-scanning direction.
