Image data is efficiently compressed without degrading image quality. An image processing apparatus includes a timing controller 2 and a source driver 3. The source driver 3 includes an RGB data receiving circuit 5, a YCC conversion circuit 6, a BTC encoding circuit 7, a frame memory 8, It has a BTC decoding circuit 9, an RGB conversion circuit 10, and an LCD drive circuit 11. Since the image data is encoded by selecting either the 2-level BTC algorithm or the 3-level algorithm according to the amount of activity in the pixel block, the image data can be efficiently compressed without degrading the image quality. In particular, even when the original image is a PC image generated by a PC, it is possible to generate encoded data that does not deteriorate image quality. [Selection] Figure 1 |
