Abstract:
1. A video processing apparatus comprising: a buffer which stores data of an image frame which comprises a plurality of lines inputted from an outside in line units; a memory unit which randomly writes and reads the data of the image frame; a video processing unit which processes and outputs the data of the image frame; and a central processing unit which inverts the data of the image frame in an upside down direction when writing the data of the image frame stored in the buffer, to the memory unit or reading the data of the image frame from the memory unit, wherein, if the central processing unit processes the data of the image frame inverted upside down during the writing, the central processing unit skips a first line of the data of the image frame inverted upside down stored in the memory unit and skips processing of the skipped first line, wherein, if the central processing unit inverts the data of the image frame in the upside down direction during the reading, the central processing unit skips a last line of the image frame stored in the memory unit and skips processing of the skipped last line, wherein the memory unit comprises a plurality of regions, and wherein the central processing unit writes the data of the image frame into one of the plurality of regions in a right side up direction and writes the data of the image frame into another of the plurality of regions in the inverted upside down direction which is opposite the right side up direction.
