摘要

The invention seeks to reduce flickering on a screen by simplifying the structure of an image processing device. An image processing device 100 includes a statistical value calculating unit 10, a correction parameter calculating unit 20, and an image correcting unit 30. The statistical value calculating unit 10 generates statistical value data 10A. The correction parameter calculating unit 20 generates a control signal in accordance with the degree of change in the scene thereby generating a correction parameter by using a low pass filter whose time constant changes based on the control signal and equalizing the statistical value data 10A. A look-up table is generated based on the correction parameter.
