Honored Contributori m doing a project in which the video in is connected to a camera
cmos JK 807A CAMERA: number of pixel: 628(h)x582(v)<PAL>, Resolution:380 lines. scaning frequency:50 Hz to display real time video on a vga monitor connected to DE2 board i want to know what is the process is there any change required in ITU656 format of DE2_TV program.
Honored ContributorHi arunkupradhan,
the DE2-TV application has been written for NTSC. If you want to update it for PAL you need to initialize the Analog Devices video codec for the PAL format. You will also have to update the verilog description for the screen size and 50Hz rate. In contrary to the DE2-TV design, you will not directly be able to change the frame rate to 50Hz for both the video camera and the VGA screen. Your VGA controller will probably have to work at 60Hz (or higher). --- Quote Start --- cmos JK 807A CAMERA: number of pixel: 628(h)x582(v)<PAL>, Resolution:380 lines. scaning frequency:50 Hz to display real time video on a vga monitor connected to DE2 board i want to know what is the process is there any change required in ITU656 format of DE2_TV program. --- Quote End ---Honored Contributorthanks 4 ur reply,that means i need to change the camera or any alternative solution is available.
