摘要

A three-dimensional noise reduction processing unit perform as a recursive noise reduction process to an input image X(n), using a motion vector MV detected by a motion vector detecting unit. A three-dimensional noise reduced image B(n) is output as a corrected original image Y(n). A two-dimensional noise reduction filter processing unit applies a two-dimensional noise reduction filter to the input image X(n). Using the motion vector MV, an interpolated image generating unit generates an interpolated image Y(n+0.5) based on a two-dimensional noise reduced image A(n). Significant degradation of an interpolated image due to false detection of a motion vector is prevented by generating the interpolated image based on the image resulted without performing the recursive noise reduction process.

1. An image processing device for performing a frame rate conversion process and a recursive noise reduction process, the device comprising:
a motion vector detecting unit configured to detect a motion vector from input images that are input consecutively; a first noise reduction processing unit configured to perform the recursive noise reduction process to the input image using the motion vector; a second noise reduction processing unit configured to apply a noise reduction filter to the input image; and an interpolated image generating unit configured to generate an interpolated image using the motion vector and based on a reference image, wherein a corrected original image obtained by a predetermined method and the interpolated image generated based on the reference image are output, the reference image being obtained by a method different from that for the corrected original image.
