Abstract
According to one embodiment, an image processing apparatus includes a panel luminance controller, a calculation module and a conversion module. The panel luminance controller is configured to control panel luminance of a self-emission type device based on intensity of ambient light. The calculation module is configured to calculate a gradation conversion function based on a characteristic amount of an input image and the panel luminance, the gradation conversion function having been provided to correct appearance of the input image. The conversion module is configured to apply the gradation conversion function to the input image, to generate an output image.
Claims14
An image processing apparatus comprising:
- a panel luminance controller configured to control panel luminance of a self-emission-type device based on intensity of ambient light;
- a calculator configured to calculate a gradation conversion function for changing the appearance of an input image, wherein the gradation conversion function is based on the panel luminance and a factor relating to the brightness or darkness of the input image;
- and
- a converter configured to apply the gradation conversion function to the input image, to generate an output image.
An image processing apparatus comprising:
- a panel luminance controller configured to
- control panel luminance of a self-emission type device based on intensity of ambient light, and
- set a gradation conversion parameter based on the intensity of the ambient light and an input gradation value and corresponding to the panel luminance;
- a calculator configured to
- calculate peak luminance to allocate to an input image, based on the panel luminance and a factor relating to the brightness or darkness of the input image,
- calculate a gradation correction function for correcting the input gradation value to a value less than or equal to the peak luminance, and
- calculate a gradation conversion function based on the corrected input gradation value;
- and
- a converter configured to apply the gradation conversion function to the input image, to generate an output image.
