  • Patent number: 7953282
    Abstract: Encoded picture data is input to an MPEG decoding circuit. Decoded picture data is generated according to motion information. The decoded picture data is output to a motion adaptive picture processor. The MPEG decoding circuit supplies the motion information to a time axis compensation circuit. The time axis compensation circuit supplies the motion information to the motion adaptive picture processor at a timing in which decoded picture data that contains the motion information is supplied from the MPEG decoding circuit to the motion adaptive picture processor. The motion adaptive picture processor determines whether picture data that is being processed is a moving picture or a still picture according to the motion information, selects a corresponding picture process, and executes the selected picture process.

  • Patent number: 5539425
    Abstract: A display unit in which a black level is set to a predetermined level in a first display screen having a first aspect ratio and a black level is set to a predetermined level in a second display screen having a second aspect ratio is provided. A darkest signal of a video signal is detected from an image area corresponding to the second display screen. The darkest signal is lowered to a predetermined level in an image area corresponding to the first display screen. In accordance with the principles of the present invention, the situation where a video signal of the second display screen that is to be lowered will not be lowered can be prevented.
