(57) ABSTRACT A system accesses an image with each pixel of the image having
luminance values each representative of a color component of the pixel. The system …

BACKGROUND Modern digital images frequently require the adjustment or reduction of the
dynamic range between lighter and darker areas. In some cases adjustment is required in …

Imaging and video capabilities have become the trend in consumer electronics. Digital
cameras, digital camcorders, and video cellular phones are common, and many other new …

BACKGROUND The present disclosure relates generally to image process ing and, more
particularly, to generating a high dynamic range (HDR) tone mapped, high-local-contrast …

Image tone adjustment using local tone curve computation may be utilized to adjust
luminance ranges for images. Image tone adjustment using local tone curve computation …

A method for tone mapping includes applying, by at least one processor, at least two tone
mapping functions to video data. The at least two tone mapping functions include a first tone …

A method for tone mapping includes configuring, by at least one processor, at least one tone
mapping function based on a measure of a distribution of luminance values within video …

A system accesses an image with each pixel of the image having luminance values each
representative of a color component of the pixel. The system generates a first histo gram for …

ABSTRACT A method for brightness and contrast enhancement includes computing a
luminance histogram of a digital image, com puting first distances from the luminance …

The present invention relates to an image processing device and a method for processing
an image. The image processing device includes a brightness improvement unit to improve …
