Abstract: In order to reduce the risk of a linear array CCD camera being damaged due to repeated debugging, the characteristics and timing of the camera were analyzed, and a CCD camera simulator based on field programmable gate array (FPGA) was designed. The whole system uses FPGA as the core device. A ROM is opened inside the FPGA to store the grayscale value of a standard image. The grayscale value is output at the falling edge of the pixel clock, and the pixel clock is counted to generate an external line synchronization signal and a line valid signal. The simulation results show that the simulation process of this linear array CCD camera simulator meets the output timing requirements of the actual camera. The design of the simulator shortens the debugging time in the project and provides a guarantee for the later acquisition and storage processing. [Author Abstract]
