Technique for Determining the Slope of a Field Pixel

Abstract: A technique for determining the slope of a field pixel is described. According to the technique, one or more sets of diagonal field pixels are downscaled (or downsampled) before they are provided to respective edge detector circuits. By downscaling the sets of diagonal field pixels before they are provided to respective detector circuits, the edge detector circuits detect diagonal edges and, in particular, shallow diagonal edges with greater accuracy. As such, the slopes assigned to the field pixels are more likely to be correct. This ultimately results in a high quality progressive video signal that can be used to generate an image that is completely or substantially free from objectionable artifacts.

Method and apparatus for mapping a multi-dimensional signal from one space to another space

Abstract: In a method of mapping data from a source space to a target space, a space transformation look-up table (LUT) that contains a plurality of locations storing information is maintained, wherein each of the plurality of locations includes information specifying a function to be evaluated. First data defined according to a multi-dimensional source space is input, and second data defined according to a multi-dimensional target space is generated, by applying information contained in the LUT to the first data.

Systems and methods for display device backlight compensation

Abstract: Systems and methods of controlling illumination of a display device are disclosed. These systems and methods can detect a plurality of luminance values in a digital image of the display device that correspond to a plurality of pixel positions of the display device. A first plurality of luminance values of the plurality of luminance values can be mapped to a first pixel position of the plurality of pixel positions of the display device, and a compensation mask value for the first pixel position can be determined based upon the first plurality of luminance values. The compensation mask value can correspond to an adjustment of a luminance value of the first pixel position. The compensation mask value can be provided to a display controller of the display device to permit the display controller to adjust a luminance value of the first pixel position to correspond more closely with luminance values associated with other pixel positions of the plurality of pixel positions of the display device based upon the compensation mask value.

3d display using partial screen illumination and synchronized shutter glass

Abstract: An electronic visual display system includes a display screen for displaying an image. The display screen has at least a first display region and at least a second display region that is approximately contiguous to the first display region. The image has at least a first portion that is displayed within the first display region and at least a second portion that is displayed within the second display region. The system further includes a first light source configured to illuminate substantially the first display region, a second light source configured to illuminate substantially the second display region, and a display device controller coupled to the first light source and the second light source which is configured to lessen an amount of light emanating from the first light source approximately when updating the first portion of the image.

Method and Apparatus for Content Adaptive Sharpness Enhancement

Abstract: A method and apparatus are provided for adaptive sharpness enhancement of image data. In on embodiment, a method for sharpness enhancement includes receiving image data for a first frame, performing linear sharpening enhancement of the image data, performing non-linear sharpening enhancement of the image data, and generating blending parameters based on the image data. The blending parameters may be generated based upon image data of the first frame, linear sharpened image data for the first frame, and non-linear sharpened image data for the first frame. The method may further include blending the image data of the first frame, the linear sharpened image data, and the non-linear sharpened image data based upon the blending parameters.
