IMAGE PROCESSING APPARATUS AND CONTROL METHOD THEREOF

摘要

An image processing apparatus reads an image out of a frame buffer by vertically flipping the image, writes the image into an output line buffer by horizontally flipping the image, divides each line, and simultaneously outputs the resulting line segments. Methods for vertical flipping, horizontal flipping, and simultaneous output are changed according to the output settings.

主权项

1. An image processing apparatus which supplies an image to a display apparatus configured to create a display in an output scanning mode in which drawing scans are performed in parallel in a plurality of subregions making up one screen, said apparatus comprising
a plurality of video processing units configured to divide the image into a plurality of partial images and process the partial images in parallel, wherein each of said plurality of video processing units includes:
a frame buffer configured to hold the partial images;a line buffer configured to hold line data;a reading unit configured to read the line data of the partial images from the frame buffer in line order corresponding to the output scanning mode;a writing unit configured to write line data which is based on the line data read by the reading unit into the line buffer in pixel order corresponding to the output scanning mode; andan output unit configured to divide the line data held by the line buffer into a plurality of items of line data and output the items of line data in parallel during one scanning interval of the output scanning mode.
