摘要： A line buffer device temporarily stores a predetermined area of original image data which are divided into small blocks, each having a small area, so as to encode the image data for each block into data having a fixed length by a compression processor. The line buffer device is composed of a first-stage line buffer group and a second-stage line buffer group. The number of line buffers in the first-stage line buffer group is smaller by one than the number of lines constituting one block and the number of line buffers in the second-stage line buffer group is the same as the number of lines constituting one block. Encoding processing time is shortened and the circuit structure is simplified.

摘要： An image processing device (21) is provided with: a noise suppression processor (23) for creating a noise-reduced image (NRs) by executing spatial filtering on a plurality of pixels, which fall within a reference range that includes a pixel of interest, in an input image (Is); and a distortion correction processor (24) for correcting distortion by local stretching or shrinking by a magnification factor (R) corresponding to the local amount of distortion in the noise-reduced image (NRs). The reference range is dynamically changed in accordance with the magnification factor (R). Control is performed so that the reference range becomes narrower as the magnification factor (R) increases.
