Image processing apparatus, image processing method and image display system

摘要

An image processing apparatus for generating an intermediate frame according to a previous frame and a next frame is provided. The apparatus includes a determining module and a selecting module. The intermediate frame includes a plurality of intermediate image blocks, each of which corresponds to a motion vector. For each intermediate image block, the determining module determines whether an interpolated image generated according to the motion vector meets a correctness requirement. According to whether the interpolated image meets the correctness requirement, the selecting module selects the interpolated image or a substitutive image different from the interpolated image to represent the intermediate image block.

1. An image processing apparatus, for generating an intermediate frame according to a previous frame and a next frame, the intermediate frame comprising a plurality of intermediate image blocks each corresponding to a motion vector, the image processing apparatus comprising:
a determining module, for determining whether each interpolated image, for each intermediate image block, generated according to the motion vectors meets a correctness requirement to generate a correctness signal; a selecting module, for selecting the interpolated image to represent the intermediate image block when the interpolated image meets the correctness requirement, and selecting a substitutive image different from the interpolated image to represent the intermediate image block when the interpolated image block fails to meet the correctness requirement, each of the intermediate image blocks corresponding to a previous image block in the previous frame and a next image block in the next frame, the image processing apparatus further comprising: an interpolating module, for generating the interpolated image corresponding to the intermediate image block according to the motion vector corresponding to the intermediate image block; a mixing module, for mixing image data of the previous image block and the next image block according to a ratio to generate a mixed image; and a weighting module, for adding a product of multiplying image data of the mixed image with a first weighting and a product of multiplying image data of the interpolated image by a second weighting to generate the substitutive image corresponding to the intermediate image block.
