Image processing method
A novel image processing method is provided. In a display device in which a video signal is individually supplied to a screen divided into two, the entire screen is subjected to up-conversion processing after being divided, and another up-conversion processing is performed for a boundary portion of the screen divided into two. The divided up-conversion processing for the entire screen and the up-conversion processing for the boundary portion are performed in parallel with the use of a plurality of arithmetic units. The divided up-conversion processing for the entire screen and the up-conversion processing for the boundary portion can be performed using different algorithms.
