A ccd drive sequence processing device

Abstract

The invention provides a charge coupled device (CCD) driving schedule processing device. The CCD driving schedule processing device comprises a timing sequence management module, a timing sequence storage module and a timing sequence output module, wherein the timing sequence storage module is used for storing a CCD driving schedule scale. The CCD driving schedule scale comprises a plurality of data lines, wherein each data line comprises CCD jumping sequential data. The timing sequence output module is connected with the timing sequence storage module and used for reading the CCD jumping sequential data in each data line from the CCD driving schedule scale of the memory module, and corresponding CCD driving schedule signals output by the CCD jumping sequential data are transmitted to a CCD device. The CCD driving schedule processing device not only solves the complicated problems of implementation scheme in the prior art, but also solves the problems that the CCD driving schedule updates and renews difficultly, and meanwhile implementation cost is low.

Description

technical field [0001] The invention relates to imaging technology, in particular to a CCD driving timing processing device. Background technique [0002] For the imaging device CCD of the camera, its work requires a corresponding driving sequence. Using FPGA can easily generate CCD driving timing. In the current prior art, a counter is usually used to control the signal edge change of the CCD driving timing. [0003] Please refer to figure 1 , which shows part of the screenshots of the CCD drive timing of the model ICX625AQA sold by Sony. Among them, the "VΦ1" signal "has 9 rising edges + 9 falling edges" in the counting interval from "0 to 6123" (only up to 4865). Generally, the following logic is used to implement: [0004] If (counter value=count value 1)||(counter value=count value 2)||...||((counter value=count value 9)), then the "VΦ1" signal rises to a high level; [0005] If (counter value=count value 1')||(counter value=count value 2')||...||((counter value=c...

Problems solved by technology

[0012] Compared with the prior art, the present invention not only solves the problem of the prior art by storing the CCD jump sequence data corresponding to the CCD drive timing signal, and then reading the data rhythmically through the jump interval parameter to generate the CCD drive timing signal. The problem of complex implementation schemes in the system also solves the problem of difficulty in upgrading and updating the timing sequence of the CCD drive, and at the same time the implementation cost of the present invention is lower
