Abstract
A video processing method for a video processing circuit includes receiving a first video source corresponding to a first pixel rate and a second video source corresponding to a second pixel rate, wherein a processing data rate of a video processing path is greater than or equal to a sum of the first pixel rate and the second pixel rate, and using the processing data rate to sequentially perform an image processing to a first image of the first video source and a second image of the second video source corresponding to the same display time, to generate a first processed image and a second processed image.
Claims10
A video processing method, for a video processing circuit, comprising:
- receiving a first video source corresponding to a first pixel rate and a second video source corresponding to a second pixel rate, wherein a processing data rate of a video processing path is greater than or equal to a sum of the first pixel rate and the second pixel rate;
- and
- using the processing data rate to sequentially perform image processing to a first image of the first video source and a second image of the second video source corresponding to a same display time, to generate a first processing image and a second processing image.
A video processing circuit, comprising:
- a first memory access unit configured to read a first video source corresponding to a first pixel rate and a second video source corresponding to a second pixel rate, wherein a processing data rate of a video processing path is greater than or equal to a sum of the first pixel rate and the second pixel rate;
- and
- an image processing unit, coupled to the first memory access unit, and configured to use the processing data rate to sequentially perform image processing to a first image of the first video source and a second image of the second video source corresponding to a same display time, to generate a first processing image and a second processing image.
