The method of obtaining the histogram, and a method of dynamically adjusting the luminance of the image processing apparatus

The present invention discloses a method for obtaining a histogram, the histogram acquisition method comprising the steps of: acquiring pixel data of the luminance motion video picture; a first minimum luminance of the luminance data and the luminance data in the luminance value the maximum frequency of the luminance data in a second separate statistical processing, corresponding to the first histogram drawn after statistical processing luminance data. The present invention also discloses a method and apparatus for processing the image luminance dynamic adjustment. The present invention can more accurately and fully reflect the image quality characteristics.
