摘要： The present invention overcomes the limitations of the prior art by providing a system and method for halftoning using time-variable halftone patterns. Successive frames that are presented to the output device are individually halftoned. The halftone pattern is changed from frame to frame. The different halftone patterns can be generated in real time, or they can be calculated prior to halftoning and stored in memory. Additionally, the halftone patterns can be generated using any conventional halftoning technique. The same halftoning technique can used to create each halftone pattern, or the halftoning techniques can be varied when creating halftone patterns. The halftoned frames are then viewed in a sequence in time. Because the halftone pattern is changing from frame to frame, the visibility of the pattern is reduced when compared with the patterns produced by prior art halftoning methods.

摘要： A method and apparatus is described for providing a consistent visual appearance of pixels of a display screen with respect to a viewing position. Variations between perceived pixel level values associated with the pixels and corresponding pixel level values may be compensated for. Variations are associated with a viewing angle between pixel location and the viewing position and compensated for by applying a respective different correction factor to each of the corresponding pixel level values based on a respective viewing angle. Accordingly different non-linear correction curves corresponding to locations may be established relating a range of pixel level values to a corresponding range of corrected pixel level values associated with the viewing position. A calibration pattern may be further be displayed and user inputs associated with locations received responsive to calibration pattern. Viewing position and non-linear correction curves may thereby be established for locations relative to the viewing position and based on user inputs. User inputs are stored with an association to a user identity. A user input is processed to obtain user identity and stored user inputs and viewing position and non-linear correction curves established based on the user inputs. Change is detected in a relative orientation between a display orientation and the viewing position and a second respective different correction factor applied to each corresponding pixel level value based on the change. Second different non-linear correction curves are established relating pixel level values to corrected values associated with relative orientations. Interpolation or an analytical function is applied to arrive at corrected pixel values. To detect changes, one or more sensors are read. A viewing position sensor senses the position of a remote device coupled to the viewer. The viewer feature tracking sensor includes a camera and means for analyzing an image for features associated with the viewer.

摘要： Methods and data processing systems are disclosed for color management in a multiple display system. In one embodiment, a computer-implemented method includes color managing media based on a color gamut of a first display. Then, the method mirrors the media in a mirrored mode onto the first display and a second display. Then, the method processes the media for the second display through a gamma information for the second display. The gamma information is for a non-mirrored mode for the second display. The first and second displays may have different color gamuts. These color gamuts can be used for generating or modifying the gamma information for the second display. The gamma information may provide a color management for the second display that is based on the second display and is independent of the first display.

摘要： Methods and data processing systems are disclosed for automatically calibrating display devices. In one embodiment, a data processing system includes a display device having a built-in image capturing device and a mirror system with at least one mirror that is operatively coupled to the image capturing device. The mirror system reflects one or more reference images in a first region of the display device and one or more references images in a second region of the display device to the image capturing device. The references images captured by the image capturing device allow a calibration of colors output from the display device. A reference image in the first region may be compared to different references images in the second region until a match is obtained. In another embodiment, an adjustable mirror system includes at least one adjustable mirror to allow adjustment of the mirror angle for the display calibration.

摘要： An automated RAW image processing method and system are disclosed. A computer receives a RAW image and metadata from a camera and interpolates an interpolated image from the RAW image so that the interpolated image is in a first color space. Predefined characterization matrices associated with the camera are obtained. Each of the characteristic matrices is associated with a different illuminant. A conversion matrix is interpolated from the characterization matrices and a white balance of the RAW image. The interpolated image is converted with the conversion matrix into a second color space. A resulting image in a rendered color space is produced from the converted image, and the resulting image is made available to an application program.

摘要： Successive frames or images of an input image that are presented to the output device are individually halftoned. A starting location within the input image for tiling one of one or more halftone techniques over the frame or image is determined. The starting location is then offset from the previously used starting location after a certain number of frames or images have been halftoned. Any halftoning technique may be used to halftone the frames or images. The halftoned frames or images are then viewed in a sequence in time.

摘要： Methods and apparatuses for color correction that includes gamma correction. One embodiment of the present invention pre-processes the native device information of a color device (e.g., a color display device) to generate pseudo-native device information such that when a single, unique function is applied on the pseudo-native device information, a customized look up table for gamma correction in a video card is generated. The customized look up table is calibrated for the optimization of color rendering for skin tone in one region in a color space while maintaining the gray colors for the user interface elements in another region in the color space.
