Abstract
When the fact that the display mode of motion picture data is a full screen mode is detected, the display control mode for sending a video signal generated by a graphics controller to an LCD is switched from a normal mode for sending the video signal to the LCD without interposition of a high quality video engine to a high quality mode for sending the video signal to the LCD with interposition of the high quality video engine. The high quality video engine enlarges the screen size of the video signal in either linear scaling mode or nonlinear scaling mode designated by a user. Scaling is validated only in the case were motion picture data are displayed in the full screen mode.
Claims13
An information processing apparatus comprising:
- a display device capable of displaying motion picture data;
- a display control portion which generates a video signal to form a display image to be displayed on the display device;
- a video processing portion which adjusts a quality of the video signal generated by the display control portion and scales a size of the video signal generated by the display control portion in either one of a linear scaling mode and nonlinear scaling mode;
- and
- a control unit which sets a display control mode for sending the video signal to the display device as a first mode for sending the video signal to the display device with interposition of the video processing portion when the quality of the video signal generated by the display control portion is adjusted, and the control unit which sets the display control mode for sending the video signal to the display device as a second mode for sending the video signal to the display device without interposition of the video processing portion when the quality of the video signal generated by the display control portion is not adjusted.
A display control method for displaying motion picture data on a display device of an information processing apparatus, the information processing apparatus including a display control portion which generates a video signal to form a display image to be displayed on the display device, and a video processing portion which adjusts the video signal generated by the display control portion and scales a size of the video signal generated by the display control portion in either one of a linear scaling mode and a nonlinear scaling mode, the display control method comprising:
- designating either one of the linear scaling mode and the nonlinear scaling mode as a scaling mode to be used by the video processing portion;
- setting a display control mode for sending the video signal to the display device as a first mode for sending the video signal to the display device with interposition of the video processing portion when the quality of the video signal generated by the display control portion is adjusted;
- and
- setting the display control mode as a second mode for sending the video signal to the display device without interposition of the video processing portion when the quality of the video signal generated by the display control portion is not adjusted.
An information processing apparatus comprising:
- a display device capable of displaying motion picture data;
- a display control portion which generates a video signal to form a display image to be displayed on the display device;
- a unit which designs either one of a linear scaling mode and a nonlinear scaling mode as a scaling mode for enlarging the motion picture data;
- a video processing portion which enlarges a screen size of the video signal generated by the display control portion in the designated mode;
- a judgment unit which judges whether display mode for displaying the motion picture data is a full screen mode or not;
- and
- a control unit which sets a display control mode for sending the video signal to the display device as a first mode for sending the video signal to the display device with interposition of the video processing portion when the display mode is judged as the full screen mode, and the control unit which sets the display control mode for sending the video signal to the display device as a second mode for sending the video signal to the display device without interposition of the video processing portion when the display mode is not judged as the full screen mode.
