Abstract: When television screen setting is not set and thus a television screen setting completion flag is not set, and a terminals-connection judgment pin takes a low level, an i/p selection screen is initially displayed on a progressive display device. However, the i/p selection screen is not displayed on an interlaced display device. When processing performed for the i/p selection screen is completed, or when the terminals-connection judgment pin takes a high level, indicating that the video input D-terminal of the display device is not connected to the video output D-terminal, an aspect ratio setting screen is displayed. After aspect ratio setting is completed, the television screen setting completion flag is set. This eliminates the need to perform the television screen setting again.

When the first video data is video data of two successive frame images having different brightness, the conversion unit performs a first frame rate converting process for converting the first video data to the second video data by outputting a frame image group made of two successive frame images in the first video data “n” times in a row at the second frame rate. Consequently, the frame rate converting process can be performed without deteriorating a visual effect such as an HDR effect, and viewing environment comfortable for the user can be realized.

Abstract: One embodiment of an edge-preserving vertical interpolation system constructs a de-interlaced video frame on a pixel-by-pixel basis using an edge-preserving vertical interpolation technique. Pixels within a pixel window centered about a selected pixel determine the direction of an intensity gradient associated with the selected pixel. A first pixel is constructed by interpolating between pixels that are perpendicular to the direction of the intensity gradient and a confidence factor is computed that indicates the likelihood that there is only one edge within the pixel window. A second pixel is constructed using a non-edge-preserving vertical interpolation technique. Interpolating between the first pixel and the second pixel based on the confidence factor generates a pixel in the de-interlaced video frame corresponding to the selected pixel.

Abstract: A method and apparatus for detecting and correcting motion artifacts in interlaced video signal converted for progressive video display. A correction is applied where interlaced video material is determined to originate from film source, thereby having been converted to video using a process known as 3-2 pulldown. Where the video material is not a result of the 3-2 pulldown process, a check is made for the presence of “pixel motion” so that corrections may be applied to smooth out the pixel motion. To determine 3-2 pulldown or field motion, a video field is compared to the field prior to the previous field to generate field error. Field errors are generated for five consecutive fields and a local minimum error repeated every five fields indicate the origination of the video material from film source using the 3-2 pulldown process.

Abstract: A content-dependent scan rate converter with adaptive noise reduction that provides a highly integrated, implementation efficient de-interlacer. By identifying and using redundant information from the image (motion values and edge directions), this scan rate converter is able to perform the tasks of film-mode detection, motion-adaptive scan rate conversion, and content-dependent video noise reduction. Adaptive video noise reduction is incorporated in the process where temporal noise reduction is performed on the still parts of the image, thus preserving high detail spatial information, and data-adaptive spatial noise reduction is performed on the moving parts of the image. A low-pass filter is used in flat fields to smooth out Gaussian noise and a direction-dependent median filter is used in the presence of impulsive noise or an edge. Therefore, the selected spatial filter is optimized for the particular pixel that is being processed to maintain crisp edges.
