Abstract
A television receiver apparatus in an embodiment includes: a video processing module configured to perform signal processing for input video signals and to output display video signals to a display panel; a selector configured to turn ON/OFF operation of low-delay processing that involves a short delay time of the display video signals with respect to the video signals as the signal processing; and a controller configured to control the video processing module to perform scaling processing conformable to the display panel when the operation of the low-delay processing is ON and when OFF according to the selector.
Claims15
A video display apparatus comprising:
- a video processing module configured to perform signal processing for input video signals and to output display video signals to a display module;
- a selector configured to turn ON/OFF operation of low-delay processing in which a delay time of the display video signals with respect to the video signals is reduced, as the signal processing;
- a frame memory configured to store the video signals for at least one frame;
- and
- a controller configured to control the video processing module to perform scaling processing conformable to the display module when the operation of the low-delay processing is ON and when OFF according to the selector, wherein
- the video processing module performs signal processing for the video signals stored in the frame memory and outputs the display video signals, and
- when the low-delay processing is ON, the controller controls the video processing module to start the signal processing after a lapse of a predetermined time from start of storage processing of storing the video signals for the at least one frame in the frame memory and before completion of the storage processing.
A video processing method for performing signal processing for input video signals to convert the video signals into display video signals to be displayed on a display module, the method comprising:
- starting storage processing of storing the video signals for one frame in a frame memory;
- performing processing selection in which operation of low-delay processing, in which a delay time of the display video signals with respect to the video signals is reduced, is turned ON/OFF as a signal processing mode;
- performing signal processing of the video signals being stored in the frame memory in which the signal processing is started after a lapse of a predetermined time from start of the storage processing and before the completion of the storage processing when the low-delay processing is ON;
- and
- performing signal processing in which scaling processing conformable to the display module is performed in either case where the low-delay processing is ON or OFF.
