Image data`s gamma correction value calculating method for image processing device, involves calculating gamma correction value based on image-specific statistical data, and using value on individual data during output of respective data

摘要

The method involves statically evaluating image data that represents individual data with respect to the brightness control of the individual data by a statistical unit (4), and allocating image-specific statistical data. A gamma correction value, which is adapted to the individual data, is calculated based on the statistical data by a gamma adaptation unit (8). The value, which is adjusted to the individual data, is utilized on the individual data during output of the respective data. The statistical data includes moment of brightness control of the respective individual data.
