Abstract
Embodiments of the invention relate to a display operable in 2D and 3D display modes. Methods and apparatus are provided for adjusting the colors and brightness of the image data and/or intensity of the display backlight based on the current display mode and/or color-grading of the image data. For example, when switching to a 3D display mode a color mapping may be performed on left and right eye image data to increase color saturation in particular regions, and/or the backlight intensity may be increased in particular regions to compensate for lower light levels in 3D display mode.
Claims30
A method for operating a display having a 2D display mode and a 3D display mode, the method comprising:
- displaying first image data in the 2D display mode;
- and,
- switching to the 3D display mode wherein switching to the 3D display mode comprises:
- displaying left and right image data for viewing respectively by viewers' left and right eyes;
- and
- performing a color mapping on the left and right image data prior to displaying the left and right image data.
A display comprising:
- an input for receiving image data;
- a color mapping unit connected to perform color mapping on received image data;
- display driver circuitry connected to display images according to image data processed by the color mapping unit;
- and
- a controller, wherein the controller is configured to control switching between a 2D display mode and a 3D display mode, wherein in controlling switching the controller is configured to:
- change color mapping parameters for the color mapping unit;
- and
- switch from displaying first image data to displaying left and right image data for viewing respectively by a viewer's left and right eyes.
An image processor for processing input image data for a display capable of switching between a 2D display mode and a 3D display mode, the image processor comprising:
- a transform unit configured to adjust colors in the image data based at least in part on whether the display is in the 2D display mode or the 3D display mode;
- and
- a mapping unit configured to map input values in the image data to output values based on one or more of the capabilities of the display and the characteristics of the image data.
