To operate properly, the Gamma LUT IP must be configured for the actual input and output image frame size. To gather the frame size information from the image video stream, the IP can be connected to the Video In to AXI4-Stream input and the Video Timing Controller core. The timing detector logic in the Video Timing Controller gathers the video timing signals. The AXI4-Lite control interface on the Video Timing Controller allows the system processor to read out the measured frame dimensions and program all downstream cores, such as the Gamma LUT , with the appropriate image dimensions.
