Abstract
Described herein are systems and methods that reduce power consumption for an electronics device including a display. The systems and methods alter video information in a display area and reduce power for a display device when a graphics item is enlarged and the enlargement threatens to increase perceived luminance for the graphics item or increase aggregate luminance for the display area. Altering the video information reduces the luminance of video information in at least the graphics item when enlarged. This may offset perceived luminance gained by human visual processing when an item increases in size. If the graphics item is smaller than the display area after enlargement, then other video information in the display area may also be altered to conserve power.
Claims20
A portable communication device comprising:
- a display including an organic light emitting diode display;
- and
- at least one processor configured to:
- identify color information of an image, the color information corresponding to at least one of a red pixel, a green pixel, or a blue pixel in relation with displaying of the image via the display,
- detect whether the color information is within a specified range determined based on a size of the image,
- adjust the color information of the image based at least in part on a result of the detection, and
- display the image according to the adjusted color information via the display such that a power consumption required to display the image is less than a power consumption required without the adjusting.
A portable communication device comprising:
- a display including an organic light emitting diode display;
- and
- at least one processor configured to:
- identify color information of a screen, the color information corresponding to at least one of a red pixel, a green pixel, or a blue pixel in relation with displaying of the screen via the display,
- detect whether the color information is within a specified range determined based on a size of the screen,
- adjust the color information of the screen based at least in part on a result of the detection, and
- display the screen according to the adjusted color information via the display such that luminance required to present the screen is less than luminance required without the adjusting.
A non-transitory machine-readable storage device storing instructions that, when executed by one or more processors, cause the one or more processors to perform operations comprising:
- identifying color information of a screen, the color information corresponding to at least one of a red pixel, a green pixel, or a blue pixel in relation with displaying of the screen via an organic light emitting diode (OLED) display;
- detecting whether the color information is within a specified range determined based on a size of the screen;
- adjusting the color information of the screen based at least in part on a result of the detection;
- and
- displaying the screen according to the adjusted color information via the OLED display such that luminance required to present the screen is less than luminance required without the adjusting.
