Abstract
Embodiments of the present invention comprise systems, methods and devices for display-mode-dependent adjustment of image code values.
Claims21
A method for display mode-dependent adjustment of image code values, said method comprising:
- detecting a display mode for a display, wherein said display comprises a display source light and a plurality of light valves modulated to form a display image based on image code values of an input image and wherein said display mode relates to a source light illumination level for said display source light;
- adjusting said source light to said source light illumination level corresponding to said display mode when said display mode meets a criterion;
- and
- adjusting code values in an input image to be displayed on said display using said display mode and said source light illumination level such that said adjusting code values compensates for said adjusting said source light to said source light illumination level when said display mode meets said criterion.

A method for display mode-dependent adjustment of image code values, said method comprising:
- detecting a display mode for a display, wherein said display comprises a display source light and a plurality of light valves modulated to form a display image based on image code values of an input image and wherein said display mode relates to a source light illumination level for said display source light;
- adjusting said source light to a first source light illumination level corresponding to said display mode when said display mode meets a first criterion;
- applying a first tone scale adjustment model to code values of an input image to compensate for said adjusting said source light to said first source light illumination level when said display mode meets a first criterion;
- and
- adjusting said source light to a second source light illumination level corresponding to said display mode when said display mode meets a second criterion;
- and
- applying a second tone scale adjustment model to code values of said input image to compensate for said adjusting said to said second source light illumination level when said display mode meets said second criterion.

An apparatus for display-mode-dependent adjustment of image code values, said apparatus comprising:
- a display, wherein said display comprises a display source light and a plurality of light valves modulated to form a display image based on image code values of an input image and wherein said display comprises a plurality of display modes related to source light illumination levels for said display source light
- a detector for detecting a current display mode for said display;
- a source light adjuster for adjusting said source light to a source light illumination level corresponding to said current display mode when said current display mode meets a criterion;
- a tone scale adjustment model for adjusting image code values;
- and
- an image adjuster for adjusting code values in an input image to be displayed on said display using said current display mode and said source light illumination level such that said adjusting code values compensates for said adjusting said source light to said source light illumination level when said current display mode meets said criterion and wherein said adjusting code values comprises applying said tone scale adjustment model.

A method for display-mode-dependent, coordinated adjustment of image code values and a display source light, said method comprising:
- detecting a display mode for a display, wherein said display comprises a display source light and a plurality of light valves modulated to form a display image based on image code values of an input image and wherein said display mode relates an input image content type and a corresponding source light illumination level for said display source light;
- adjusting said source light to said source light illumination level corresponding to said display mode when said display mode meets a criterion;
- and
- adjusting code values in an input image to be displayed on said display using said display mode and said source light illumination level such that said adjusting code values compensates for said adjusting said source light to said source light illumination level by increasing code value brightness when said source light illumination level decreases, said adjusting code values occurring when said display mode meets said criterion.
1 more element
An apparatus for display mode-dependent, coordinated adjustment of image code values and a display source light illumination level, said apparatus comprising:
- a display, wherein said display comprises a display source light and a plurality of light valves modulated to form a display image based on image code values of an input image and wherein said display employs a plurality of display modes related to input image content types and corresponding source light illumination levels for said display source light;
- a detector for detecting a current display mode for said display;
- a source light adjuster for adjusting said source light to a source light illumination level corresponding to said current display mode when said current display mode meets a criterion;
- a tone scale adjustment model for adjusting image code values;
- and
- an image adjuster for adjusting code values in an input image to be displayed on said display using said current display mode and said source light illumination level such that said adjusting code values compensates for said adjusting said source light to said source light illumination level by increasing code value brightness when said source ht illumination level decreases said adjusting code values occurring when said current display mode meets said criterion and wherein said adjusting code values comprises applying said tone scale adjustment model.
