The primary issue regarding the transmission of digital video to automobiles is limited bandwidth. To help combat bandwidth issues, compression techniques have been developed to reduce the high bit rate required for transmission and storage. However, methods for improving the perceived quality of digital imagery, particularly at low bit rates, are critical. The present invention discloses a technique that will improve the perceived quality of digital imagery to the viewer by using selective post-processing of decompressed digital video. The human visual system (HVS) is very sensitive to human eyes and faces. Regions of interest (ROI), such as human eyes or faces, are selectively post-processed in appropriate video frames prior to being displayed to the viewer. If a subject's eyes are sharp, the viewer will perceive good image quality, despite poor rendition elsewhere. If the subject's eyes are blurry or poorly rendered, the frame will appear poor to the viewer, despite sharpness elsewhere.

As the number of contents which a user can access (TV programs, images stored on HDD or Internet news) is increasing, the contents a viewer wishes to view is becoming increasingly diverse, and consequently the question of how to view these contents efficiently is now a major problem.
