| Abstract: | A method of acquiring data and displaying the image of a CCD camera that has multi taps is proposed in this paper Data for the CCD camera are stored in a hard disk in real time by using the multi thread technique The data are broken into several blocks and the blocks are stored sequentially in the hard disk by adopting a timer interrupter The acquired data of the CCD camera are transformed into standard image formats and displayed In the paper, the CCD camera has 5 taps and the data transmission frequency for each tap used is 10MBit/s The method is verified using experiments |
| Keywords: | charge coupled devices(CCD) linear CCD image process multi thread technique |
