A motion vector detecting unitdetects a motion vector Vof an input image X(n), and an interpolating vector generating unitgenerates an interpolating vector Vin accordance with the motion vector V. In a two-dimensional display mode, the input image X(n) is output as an original image, and an image generating unitgenerates an interpolated image X(n+0.5) in accordance with the interpolating vector V. In a three-dimensional display mode, the input image X(n) is output as a left-eye image L(n), and the image generating unitgenerates a right-eye image R(n+0.5) in accordance with a sum of the interpolating vector Vand a parallax vector Vinput from the outside. The image generating unit is shared in a frame rate conversion process and a three-dimensional conversion process, and the right-eye image is generated at the same location as the interpolated image in time axis. In this way, image quality is increased when a moving image is displayed with a small amount of circuit.

Image processing device, image processing method, image display apparatus, and image display method

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.
