Embodiment Construction

[0016] best practice

[0017] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] Referring to Fig. 1 and Fig. 2, this embodiment includes five units: an image acquisition and compression processing unit, a main processing unit, a storage unit, an auxiliary control unit, and a display output unit. The image acquisition and compression unit of the present invention carries out digital coding (for example: adopting CCIR601, CCIR656 standard) to input n (n is a natural number) original image video signal of this unit, and to the n original image coding data (streaming) after digital encoding ) to carry out image compression processing (for example: according to the image compression standards such as the MPEG series of ISO / IEC and the H.263 of ITU-T, etc., WAVELET or other effective encoding and compression techniques can also be used), and at the same time select m (m≤n) The original image encoding data (...

Abstract

This invention discloses a method of digital image process recording and thereof apparatus. The purpose of the invention will overcome the shortcomings in the prior art that only one preset fixed compressing pattern (method) would be used to compress and process and record all the images. This invention will be implement as followed: the original input image compression process unit use two or more patterns (methods) to compress and process; the compressed data (stream) after processing on the input main processor separately recorded at memory unit. Digital image process recording apparatus includes image collection compression processing unit, main processor unit, and memory unit. The collection compression-processing unit has two or more compression processing units. This invention will apply to large capacity digital image memory of digital hard disk recorder, digital tape recorder and optical disk recorder and the like.

Description

technical field [0001] The invention relates to an image processing and recording method and device, in particular to a method and device for digitally encoding, compressing and recording video signals. Background technique [0002] In the prior art, Japan's SONY HSR-IP digital surveillance video recorder is provided with a hard disk and a digital tape recording double storage device, and is connected as a front and rear stage. After storing full image data on the hard disk, the image data is transferred from the hard disk to the data tape in the digital tape recorder of the subsequent stage, and then new image data is stored on the hard disk. Due to the replaceable data tape, the storage capacity of the system can be expanded infinitely, which meets the requirements of large-capacity digital image recording to a certain extent. In addition, the existing method and device thereof can also record at a rate of 25 frames / second (PAL system) or less than 25 frames / second (PAL s...
