We know that the point-to-point image display effect is the best. After reducing the image, if only ordinary graphics processing technology or general FPGA graphics processing algorithm is used, the edges of the image will appear jagged, and even pixels will be missing. The brightness will also decrease. High-end image processing chips or FPGA systems that use complex graphics processing algorithms will maximize the display effect of reduced images.
