Abstract
This image processing method for the conversion of an image with a first number of bits per pixel, for example 16 bits per pixel, into an image with a second number of bits per pixel, for example 18 bits per pixel, includes generating additional coding bit values for the components (Ri, Gi, Bi) of each pixel starting from the component values of adjacent pixels and generating the converted signal from the additional coding bits.
Claims22
An image processing method for conversion, within an electronic device, of an image with a first number of bits per pixel into an image with a second number of bits per pixel greater than the first number of bits per pixel, the signal to be converted and the converted signal respectively comprising a set of pixels each associated with red, green and blue component values forming a frame with the first number of pixels and a frame with the second number of pixels, the method comprising:
- generating additional bit values, via an image processing device of the electronic device, for coding component values of each pixel starting from component values of adjacent pixels;
- and
- using the additional bit values for generating the converted signal with the image processing device.
An electronic device comprising:
- a frame memory;
- and
- an image processing device cooperating with said frame memory for conversion of a signal with a first number of bits per pixel into a signal with a second number of bits per pixel greater than the first number of bits per pixel, the signal to be converted and the converted signal comprising a set of pixels each associated with red, green and blue component values forming a frame with the first number of bits and a frame with the second number of bits, respectively;
- said image processing device generating additional bit values for coding the components of each pixel starting from the component values of adjacent pixels, and generating the converted signal starting from the coding bits for the values of the red, green and blue components of the signal to be converted and from the additional bits.
