<P>PROBLEM TO BE SOLVED: To provide an image processing device that carries out dynamic correction with a small circuit scale, simultaneously if plural corrections are included, without the need of direct processing by a CPU. <P>SOLUTION: An image processing device 10 that carries out correction of an input image using a correction curve comprises: a setting register part 20 that outputs an initial value of a parameter for determining a coefficient of the correction curve; a statistical analysis part 40 that statistically analyzes image data of the input image; a parameter generation part 30 that changes the initial value of the parameter based on statistical information obtained from the statistical analysis part; and a correction output part 50 that sets a coefficient of the correction curve based on the parameter changed by the parameter generation part, and corrects and outputs pixel values for respective pixels of the input image based on the correction curve. The correction curve is a function of the third order or more, and the parameter has less order than that of the correction curve. <P>COPYRIGHT: (C)2012,JPO&INPIT |
