    摘要: A super resolution (SR) method or system with database-free texture synthesis is disclosed. An input image is up-sampled to result in an up-sampled image. It is determined whether the input image possesses a smooth region. Edges of the up-sampled image are enhanced, and the enhancing edges step is bypassed if the smooth region has been detected. The enhanced or unenhanced up-sampled image is texture synthesized by taking the input image as texture example, thereby resulting in a synthesized image.

    摘要: An overdrive system adaptable for a dynamic gamma generator is disclosed. A current gray-to-voltage converter (G/V) converts image data of a current frame from gray code to voltage level, and a previous gray-to-voltage converter (G/V) converts image data of a previous frame from gray code to voltage level. The voltage level of current frame and the voltage level of previous frame are inputted to an overdrive-voltage lookup table to retrieve an overdrive voltage level. Afterwards, a voltage-to-gray converter (V/G) converts the retrieved overdrive voltage level from voltage level back to gray code, resulting in an overdrive gray code. Accordingly, the overdrive gray code is compensated. Alternatively, the overdrive gray code is used to update an overdrive-gray-code lookup table, an output gray code of which is fed to the source driver.

    摘要: An image processing method applied in an image processor for processing an image including first pixels each having a corresponding pixel value. The pixel values of first pixels are distributed within a first distribution range. Second pixels comprise a region and are obtained from first pixels when a difference between pixel values of adjacent second pixels is less than a predetermined value. Gained pixel values are obtained after applying a gain to the image. An amount of distortion is obtained by summing up weighted differences between a reference pixel value and gained pixel value of first pixels having gained pixel value not distributed within first distribution range. A weighting factor does not equal to 1 when first pixel is within the region, and equals to 1 when first pixel is outside the region. The gain is updated according to the distortion. Processed image is obtained by applying the updated gain.
