Abstract
The invention provides an image processing device that reduces flickering on a screen by simplifying the structure of an image processing device. The image processing device can include a statistical value calculating unit, a correction parameter calculating unit, and an image correcting unit. The statistical value calculating unit can generate statistical value data. The correction parameter calculating unit equalizes the statistical value data using the low pass filter whose time constant changes according to whether change occurs in the scene, thereby generating the correction parameter. A look-up table is generated based on the correction parameter.
Claims10
An image processing device for performing image processing on image data, the image processing device comprising:
- a statistical value calculating device that performs statistical processing on the image data to generate statistical value data representing statistical values;
- a scene detecting device that detects whether a change occurs in a scene based on the image data;
- a correction parameter calculating device that weights the statistical value data of a plurality of frames in accordance with the detection result by the scene detecting device to calculate a correction parameter;
- and
- an image correcting device that performs image correction processing on the image data based on the correction parameter.
An image processing method of performing image processing on image data, the method comprising:
- performing statistical processing on the image data to generate statistical value data representing statistical values;
- detecting whether a change occurs in a scene based on the image data;
- calculating a correction parameter by weighting the statistical value data of a plurality of frames in accordance with the result of detecting scenes;
- and
- performing image correction processing on the image data based on the correction parameter.
An image processing program for performing image processing on image data that instructs a computer to:
- perform statistical processing on the image data to generate statistical value data representing statistical values;
- detect whether a change occurs in a scene based on the image data;
- weight the statistical value data of a plurality of frames based on the detection result to calculate a correction parameter;
- and
- perform image correction processing on the image data based on the correction parameter.
