Abstract

The invention provides an information recording method. The method comprises the following steps that a CPLD (Complex Programmable Logic Device) is used for transmitting image data to an encoding chip to be compressed and encrypted through format conversion and filtration after finishing reception of the image data; the encoding chip is used for sending the data back to the CPLD after finishing compression and encryption, and the CPLD controls a bus interface time sequence of an AGP (Accelerated Graphics Port) and uploads the data to an upper computer. The invention provides an image signal acquiring and processing method which has the capabilities of improving the signal transmission and storage speed and reducing the requirements on the channel width and the size of a storage space.

Description

technical field

[0001] The invention relates to signal acquisition, in particular to an image signal acquisition and processing method. Background technique

[0002] With the development of image and video processing technology, network technology and automatic control technology, video surveillance system has transitioned from early analog monitoring to digital network monitoring. The digital video monitoring system is based on the compression, transmission, storage and playback of digital video, and adopts advanced digital image compression, encoding, decoding and transmission technology to realize visual monitoring. Traditional video capture systems only support video data in several formats, and it is difficult to clearly capture instantaneous pictures of rapidly changing targets. However, many high-frame-rate cameras simply capture images without digitalizing the signals. Analysis and processing make the channel transmission and storage speed of image data unable to ge...
