20080204472 | Method and/or apparatus for color space reduction for transcoding subpicture elements - An apparatus including a first circuit, a second circuit and a third circuit. The first circuit may be configured to collect color statistics. The second circuit may be configured to sort colors based upon the color statistics collected by the first circuit. The third circuit may be configured to generate a mapping function between the sorted colors and a color space of a receiving standard. | 08-28-2008 |
20090021526 | DETERMINATION METHOD FOR WHITE-POINT AND CORRECTION METHOD OF THE WHITE BALANCE - A determination method for white-point and a correction method of the white balance are disclosed. In the determination method for white-point of the white balance, first gray cards with different reflection coefficients are detected according to the properties of an image sensing device. Next, the white-point gray line of a first color temperature and the white-point gray line of a second color temperature are intersected on a white-point plane to form a fan area, so as to set the white-point range of the low saturation of the image sensing device. Next, the vertical projection for an image datum is calculated to obtain a placement datum on the white-point plane, and a difference value between the image datum and the placement datum is calculated. Finally, whether the image datum is a white-point is determined according to the difference value and relationship between the placement datum and the fan area. | 01-22-2009 |
20090021527 | METHOD FOR DISPLAYING BITMAP WITH ADDITIONAL COLORS - An exemplary method for displaying bitmap with additional colors, includes: reading a bitmap and a first palette associated with the bitmap from a memory; dividing the bitmap into a color-unchanging portion and a color-changing portion; reading a second palette from the memory; associating the color-changing portion with the second palette; and displaying the color-unchanging portion using colors from the first palette and the color-changing portion using colors from the second palette. | 01-22-2009 |
20100321401 | SYSTEMS AND METHODS FOR COMBINING IMAGES INTO A FILE USING MULTIPLE COLOR PALETTES - Image data systems and methods combine a plurality of images into a single multiple-palette image data file, or generate a selected image from the multiple-palette image data file. An exemplary embodiment receives first pixel information for a first pixel of a first image, the first pixel having a first color; receives second pixel information for a like-located second pixel of a second image, the second pixel having a second color; and specifies a color palette location value that identifies a first color palette array element in a first color palette of the first image and identifies a second like-located color palette array element in a second color palette of the second image. First color information stored in the first color palette array element defines the first pixel color. Second color information stored in the second image data color palette array element defines the second pixel color. | 12-23-2010 |
20110157217 | METHODS AND SYSTEMS FOR SUB-PIXEL RENDERING WITH GAMMA ADJUSTMENT - Sub-pixel rendering with gamma adjustment allows the luminance for the sub-pixel arrangement to match the non-linear gamma response of the human eye's luminance channel, while the chrominance can match the linear response of the human eye's chrominance channels. The gamma correction allows the sub-pixel rendering to operate independently of the actual gamma of a display device. The sub-pixel rendering techniques with gamma adjustment may be optimized for the gamma transfer curve of a display device in order to improve response time, dot inversion balance, and contrast. | 06-30-2011 |
20120113132 | DEVICES AND METHODS FOR PROVIDING AN ENHANCED MONOCHROMATIC DISPLAY - A method for grayscale display of a desired output shade comprises transmitting an enhanced grayscale input signal for the desired output shade to an enhanced grayscale engine. The input signal including a plurality of shade bits and a plurality of select bits. The method further comprises decoding the plurality of shade bits and the plurality of select bits to select an intermediate shade from a plurality of intermediate shades. The method further comprises forming an enhanced grayscale display. The method further comprises receiving the enhanced grayscale display signal from the enhanced grayscale engine and displaying an enhanced grayscale image on an output display. Responsive to a first user input, a standard grayscale display signal is selected. The standard grayscale display signal is received and a standard grayscale image is displayed on the output display. | 05-10-2012 |
20120249574 | METHOD AND APPARATUS FOR REDUCED GATE COUNT GAMMA CORRECTION - A cubic, or other polynomial, approximation to a panel's gamma function. Embodiments contemplate a display system configured to apply a panel gamma function that is a third-order polynomial function, as well as its substantial inverse. This third order function is often easier to implement, and yields lower gate count than current power law gamma functions. | 10-04-2012 |
20130235072 | CONTENT METADATA ENHANCEMENT OF HIGH DYNAMIC RANGE IMAGES - Image data is encoded for distribution in a lower bit-depth format. The image data has a range that is less than a maximum range and is mapped to the lower bit depth format using a mapping such that a ratio of a range of the lower bit depth representation to a maximum range of the lower bit depth representation is greater than a ratio of the range of the image data is associated with lower bit depth representation. The metadata may be used downstream to reverse the mapping so that tonal detail is better reproduced. | 09-12-2013 |
20150325008 | SYSTEMS AND METHODS FOR ENHANCING DISPLAYED IMAGES - A method of enhancing an image includes displaying an image, receiving eye-tracking information associated with the displayed image, and identifying a region of interest in the displayed image using the eye tracking information. The method further includes enhancing the region of interest and displaying the enhanced region of interest adjacent to or superimposed upon an unenhanced region of the displayed image. | 11-12-2015 |
20150339966 | DISPLAY DEVICE AND IMAGE PROCESSING DEVICE - A display device includes an image processing unit that performs image processing on image data input from the outside, and performs display output corresponding to the image data on which image processing is performed by the image processing unit. The image processing unit includes a first processing circuit that simply replaces colors of an image to limit the number of colors used for the image to a predetermined number equal to or smaller than 16, a second processing circuit that performs image processing including arithmetic processing for improving luminance of a plurality of pixels constituting the image displayed on the display device corresponding to the image data; and a switching unit that causes the second processing circuit to perform image processing, and causes the first processing circuit to perform image processing when performing the image processing while saving more power than the second processing circuit. | 11-26-2015 |
