Image processing apparatus and image processing method
The feature amount of each pixel of an image is received. If the frequency value of the feature amount is registered in the second memory accessible at higher speed than the first memory which stores frequency values of respective feature amounts, the frequency value in the second memory is increased. If the frequency value is not registered, the frequency value is read out from the first memory into the second memory, and increased. With this processing, a histogram of the feature amounts of the respective pixels of the image is generated. The bins of the histogram are rearranged so that bins with high frequency values are close to each other in the histogram.
