Abstract
According to the still image encoder, as to frame data inputted from the digital video camera, odd field data is held in the odd field memory and even field data is held in the even field memory. The control section divides odd field data and even field data into predetermined blocks, calculates the absolute value total of differences between each pixel data in odd field data and each pixel data in even field data, and compares the total with the predetermined threshold. The DMA controller transfers pixel data of the block in the odd field data to the even field memory when the total is larger than the threshold. The control section codes frame data consisting of odd field data and even field data into JPEG data.
