Embodiment Construction

[0034] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0035] image 3 is a block diagram illustrating an embodiment of a video preprocessing device according to the present invention. refer to image 3 , the central processing unit (CPU) 310 executes the software unit. The software unit controls the operation of the hardware unit (not shown) through a register file.

[0036] The system control unit 320 transmits a control command of the central processing unit (CPU) 310 to the hardware unit. If the CPU 310 writes operation data into a register file (not shown), the system control unit 320 interprets the operation data, thereby executing commands of the software unit according to a predetermined protocol.

[0037]The register file control unit 330 controls the register file received from the CPU 310 in response to a control command of the system control unit 320 and a predetermined proto...

Abstract

It relates to a video preprocessing / postprocessing device capable of stably operating at high speed with a small amount of memory by utilizing a new hardware-software cooperation method, and provides a method used by the device. A video preprocessing method for efficiently capturing video includes the steps of: sequentially assigning a number to a plurality of storage areas, and cyclically incrementing the number in response to a frame synchronization signal; checking the memory area being stored in response to the frame synchronization signal, and capturing incoming video data; And storing the captured video data in a predetermined order in the memory area. A video post-processing method for effectively displaying video includes the steps of: sequentially assigning a number to a plurality of storage areas, and cyclically incrementing the number in response to a frame synchronization signal; displaying the memory area in response to the frame synchronization signal, checking the displayed storage area, and resetting the displayed storage area with a predetermined number; sequentially storing the video data in the memory area; and sequentially displaying the video data stored in the memory area.

Description

technical field [0001] The present invention relates to a video pre-processing / post-processing device, and more particularly, to a video pre-processing / post-processing device capable of stably operating at high speed with a small amount of memory by utilizing a new hardware-software cooperation method, and to A method used by this device. Background of the invention [0002] In general, video data input to a camera is stored in a memory in response to a capture command that encodes the video data. Since a display device processes 30 frames per second, it takes a minimum of 33 milliseconds (ms) to process a frame. Therefore, the hardware unit generates a vertical synchronization (Vsync) signal to indicate the capture probability every 33 ms, and the software unit sends a capture command and a memory address to the hardware when Vsync is generated. The hardware unit then captures the video data in response to the capture command in the memory. [00...
