ABSTRACT:
A video image processing apparatus comprising with a frame memory for temporarily storing field video data from a recording medium, an interpolation processor module for interpolating the field video data stored in the frame memory and a memory control module for controlling writing to and reading from the frame memory, and a CPU for determining field attribute information. In interpolation processing the write line position of the field video data to the frame memory is modified to the odd line position or even line position, depending on whether the field attribute information about the field video data is odd or even. According to the video image processing apparatus, no discrepancy between the odd field and even field takes place when the field video data is interpolated and reproduced.
