Document Type and Number:
Japanese Patent JP4201602
Kind Code:
B2
Abstract:
An image processing apparatus ( 100 ) for improving images comprising a classification unit ( 102 ) for setting classification values to various regions of the images, and an improvement unit ( 104 ) for improving the image based on the classification values of the regions. The classification unit ( 102 ) takes into account only those pixels of the image that have a color value which is substantially equal to one of the color values from a predetermined range of color values. Based on these pixels the classification unit ( 102 ) determines whether the pixels belong to texture or to flat regions by comparing 2 histograms, one taking into account all the pixels with the color in the predetermined range of color values, the second one counting only these same pixels if their luminance value differs more than a given threshold form the luminance of their neighbor.
