IMAGE PROCESSING METHOD AND IMAGE PROCESSING DEVICE Russian patent published in 2014 - IPC H04N5/232

Abstract RU 2508604 C2

FIELD: physics.

SUBSTANCE: brightness distribution is determined for each of multiple image data portions, the characteristic value of each brightness distribution is calculated from said brightness distribution and a correcting value is found for tonal correction, which is carried out with respect to the combined image data based on the obtained characteristic value of brightness distribution.

EFFECT: carrying out tonal correction to obtain a combined image, having suitable brightness and contrast.
