摘要:
Aspects of the present invention relate to systems and methods for enhancing privacy in a multi-view display. Some aspects relate to creating an image mask dependent on the presence of text in an image displayed on the primary view of a multi-view display. The generated image mask may be displayed on the secondary views of a multi-view display to provide increased obscurity of the primary view image from unwanted onlookers, thereby enhancing primary viewer privacy.
摘要:
A display is backlit by a source having spatially modulated luminance to attenuate illumination of dark areas of images and increase the dynamic range of the display.
摘要:
A method for mapping/enhancing the color of an image to be displayed on a display includes receiving an image having a plurality of pixels where each of the pixels has a plurality of color components. The image is processed using a pair of gamut color mapping operations in combination with skin-tone pixels detection to modify the image in a suitable manner for presentation on the display, wherein the technique includes color temperature compensation.
摘要:
A method of processing an image includes receiving an image to be displayed. Then at least one selective region of the image that has a transition from at least one of dark to bright and bright to dark is determined. The image is modified to include additional information so as to increase the perceived dynamic range of the image proximate the transition when the image is displayed on a display.
摘要:
A method for enhancing the color of an image to be displayed on a display includes receiving an image having a plurality of pixels where each of the pixels has a plurality of color components. The image is filtered using a spatial filter in such a manner that the lower frequency content of the image is enhanced in such a manner that the color gamut of the lower frequency content is increased. The filtered image is modified such that the higher frequency content of the image to obtain a modified image that includes the higher frequency content and the lower frequency content.

Embodiments of the present invention provide systems and methods for converting a higher-resolution image to a lower-resolution image with reduced visible errors. These embodiments comprise splitting a higher-resolution opponent color domain (OCD) image into separate initial luminance and initial chrominance channels followed by sub-pixel sampling on said initial luminance channel thereby creating an additive color domain (ACD) luminance image. This ACD luminance image is then converted into an OCD luminance image and split into separate sub-pixel sampled (SPS) luminance and SPS chrominance channels. The SPS chrominance channels are high-pass filtered and the initial chrominance channels are low-pass filtered. The filtered initial chrominance channels are sub-sampled and combined with the high-pass filtered SPS chrominance channels. These combined chrominance channels are then combined with said SPS luminance channel to form an error-reduced lower-resolution image.
摘要:
A system encodes video by detecting the location of a facial region of a frame of the video. Sensitivity information is calculated for each of a plurality of locations within the video based upon the location of the facial region. The frame is encoded in manner that provides a substantially uniform apparent quality of the plurality of locations to the viewer when the viewer is observing the facial region of the video.
摘要:
A system for compressing and transmitting a digital image signal over a limited bandwidth communication channel, transform codes the image values and quantizes the transform coefficients according to a two-dimensional model of the sensitivity of the human visual system. The model of the human visual system is characterized by being less sensitive to diagonally oriented spatial frequencies than to horizontally or vertically oriented spatial frequencies, thereby achieving increased compression of the image.
摘要:
A display includes an integrated imaging sensor and a plurality of pixels. The imaging sensor integrated within the display includes a plurality of individual sensors each of which provides an output. The content of the display is modified based upon the sensed content.
