Abstract
An image processing apparatus and an image processing method are provided. A storage unit of the image processing apparatus stores an image and a piece of intensity statistical information of the image. The piece of intensity statistical information records that the image has a first number of pixels having a first intensity value, a second number of pixels having a second intensity value, and a third number of pixels having a third intensity value. A micro-processing unit of the image processing unit calculates a centralization degree of the second intensity value in the image according to the first number, the second number, and the third number. If the centralization degree is greater than a threshold, the micro-processing unit adjusts the intensity value of a pixel having the second intensity value in the image according to the second intensity value and the intensity value of the at least one neighboring pixel of the pixel.
