Abstract
The utility model relates to the field of film and television camera shooting, in particular to a high definition film camera, which overcomes the technical defects of small compression ratio, the non-automatic switching of low illumination level, poor color rendition degree and low signal to noise ratio existing in the traditional film camera. The utility model provides the high definition film camera, which comprises a digital imaging module, a digital image processing module, an image output and storage module, which are connected in series. The camera is characterized in that the digital image processing module is a field programmable gata array (FPGA) chip. The high performance digital processing chip which takes the FPGA as a core is adopted to rewrite and optimize motion joint photographic experts group (MJPEG) or joint photographic experts group (JPEG) 2000 compression algorithm through programming. The camera has the advantages of high compression ratio, the non-automatic switching of low illumination level, better color rendition degree and high signal to noise ratio.
Description
Technical field
The utility model relates to video display shooting field, particularly a kind of high-definition movie video camera.
Background technology
Conversion regime and the compress mode of digital signal and the recording mode of tape of existing camera lens, CCD, the signal of telecommunication, effect is all unsatisfactory.Promptly use the captured picture conversion that goes out of best cinefilm to be digital signal, the resolution of each lattice picture is 4,096 * 2, and 400, have that compression ratio is little, low-light (level) can not be changed automatically, the color rendition degree is poor, signal to noise ratio is low.
Summary of the invention
The technical assignment of the technical problems to be solved in the utility model and proposition is to overcome the aforementioned techniques defective that existing film camera exists, a kind of high-definition movie video camera is provided, and described video camera compression ratio is big, low-light (level) is changed automatically, the color rendition degree is good, signal to noise ratio is high.
For achieving the above object, the utility model is taked following technical scheme: a kind of high-definition movie video camera, comprise digital imagery module, Digital Image Processing module, image output and the memory module of serial connection successively, it is characterized in that described Digital Image Processing module is a fpga chip.It is the high-performance digital processing chip of core that the utility model adopts FPGA, the compression algorithm of MJPEG or JPEG2000 is rewritten and optimizes by programming, realizes the video compression technology of MJPEG or JPEG2000, the compression ratio height, and handle very flexible; Multiple functional, low-light (level) is changed automatically; Minimal illumination reaches 0.1Lux/F1.2; High color reduction degree; High s/n ratio.Described fpga chip is a kind of high-performance digital processing chip, can buy.
At present on the market also directly can not be to 4K(4,096 * 2,400) image carries out in real time the chip of (more than per second 25 frames) MJPEG or JPEG2000 compression, adopt high performance general dsp also to have little time compression, Digital Image Processing module of the present utility model is a core with high performance fpga chip, characteristics by its hardware rewrite the compression algorithm of MJPEG or JPEG2000 and optimize, thereby realize above-mentioned functions.
