Abstract
An image adjusting method is applied to a display with an ambient light sensor. The image adjusting method includes utilizing the ambient light sensor to detect surrounding illumination of the display, adjusting backlight brightness of the display according to the surrounding illumination, adjusting intensity of pixels with specific gray-scale values on the display via a first amending function, and adjusting intensity of other pixels excluding the foresaid pixels having the specific gray-scale values on the display via a second amending function. The first amending function is varied according to the surrounding illumination, and the second amending function is not varied according to the surrounding illumination.
Claims16
An image adjusting method is applied to a display with an ambient light sensor, the image adjusting method comprising:
- utilizing the ambient light sensor to detect surrounding illumination of the display;
- adjusting backlight brightness of the display according to the surrounding illumination;
- adjusting intensity of pixels with specific gray-scale values on the display via a first amending function, wherein the first amending function is varied according to the surrounding illumination;
- and
- adjusting intensity of other pixels excluding the foresaid pixels having the specific gray-scale values on the display via a second amending function, wherein the second amending function is not varied according to the surrounding illumination.
A display with an automatic image optimizing function, the display comprising:
- a panel unit adapted to display an image;
- an ambient light sensor disposed by the panel unit and adapted to detect surrounding illumination of the panel unit;
- a storing unit adapted to store a plurality of amending functions;
- and
- a processing unit electrically connected to the panel unit, the ambient light sensor and the storing unit, the processing unit being adapted to read the surrounding illumination acquired by the ambient light sensor, to adjust backlight brightness of the panel unit according to the surrounding illumination, to adjust intensity of the pixels with the specific gray-scale values on the panel unit via a first amending function of the amending functions, and to adjust intensity of other pixels excluding the foresaid pixels having the specific gray-scale values on the panel unit via a second amending function of the amending functions, wherein the first amending function is varied according to the surrounding illumination and the second amending function is not varied according to the surrounding illumination.
