Abstract
A display apparatus includes: a backlight module; a first panel configured to transmit light irradiated from the backlight module; a second panel configured to display an image on a screen by transmitting the light transmitted through the first panel; and a control unit configured to control a transmittance of the first panel based on a second image generated by applying smoothing to at least a part of a first image. A strength of smoothing applied to a first region of the first image corresponding to a center of the screen is lower than a strength of smoothing applied to a second region of the first image, the second region being different from the first region.
Claims21
A display apparatus comprising:
- a backlight;
- a first panel configured to transmit light irradiated from the backlight;
- a second panel configured to display an image on a screen by transmitting the light transmitted through the first panel;
- and
- a control unit configured to control a transmittance of the first panel based on a second image generated by applying smoothing to at least a part of a first image, wherein
- the control unit performs processing to:
- divide the screen into at least a first region, corresponding to a center of the screen, and a second region, different from the first region, and
- differentiate a strength of the smoothing applied to a first image region of the first image corresponding to the first region of the screen and a second image region of the first image corresponding to the second region of the screen, such that the strength of smoothing applied to the first image region of the first image is lower than the strength of smoothing applied to the second image region of the first image.
