  • Publication number: 20120313842
    Abstract: The present invention is to provide an image device. The image device includes a plurality of sections. Each section includes a first pixel group, a second pixel group, a third pixel group and a fourth pixel group. The first pixel group comprises at least one first color dot and a second color dot or a fourth color dot, the second pixel group comprises at least one third color dot and the second color dot, the third pixel group comprises at least one fourth color dot and the second color dot, the fourth pixel group comprises at least one fifth color dot or at least one second color dot. Any four adjacent the first pixel group, the second pixel group, the third pixel group and the fourth pixel group arranged in a 2×2 matrix reach a white balance.

  • Publication number: 20120092237
    Abstract: An image device includes a plurality of pixel groups. Each pixel group includes a plurality of dots arranged in a predetermined identical matrix form, and each pixel group has at least one first color dot, at least one second color dot, at least one third color dot and at least one fourth color dot. Any repeated sequence of consecutive color dots in a row direction and in a column direction comprise at least one first color dot, at least one second color dot, at least one third color dot, at least one fourth color dot. The advantage of the invention is to provide all multi-primary colors in a single row or column so that by using subpixel rendering method, black and white lines can be formed in rows or columns, thus reducing the number of columns in a multi-primary colors display.

  • Publication number: 20120032947
    Abstract: A 3D/2D multiprimary color image device is provided with an optical unit to direct one image to the left eye and another image to the right eye. Each color dot of the multiprimary color image device comprises at least two color sections controlled independently. To display a 3D image, one section of a color dot is for displaying a left eye image while another section of the same color dot is for displaying a right eye image. To display a 2D image, both sections of a color dot for the left eye and for the right eye displaying the same image independently.

  • Patent number: 7742205
    Abstract: The invention relates to a color matching method for transforming a color representation of a first set of color primaries with a plurality of first signals to a second set of color primaries with a plurality of second signals in a first domain. The color matching method of the invention is to consider the characteristics of human visual perception. Since human is more sensitive to the luminous intensity than chrominance, the color matching method of the invention is considered to match the luminous intensity. The color matching method of the invention can minimize the intensity difference by utilizing the optimality of resource distribution. An additional step of smoothing the intensity difference among color primaries at the level of color primaries is appended. It enhances the visual quality especially for the images with a gradual change in numerous levels of color. Besides, when the color is outside the gamut, we keep the information of luminance by adding extra white.

  • Patent number: 7286136
    Abstract: The invention relates to a display and an image data processing system. According to the arrangement of the display, two color dots having lower light intensity than the other two color dots in a white balance status are disposed on diagonal positions of the pixel group. Therefore, the display of the invention can improve the color balance in the pixel group to avoid visible dark vertical line. The image data processing system of the invention utilizes the weighted dot rendering device for pre-compressing data. We can expect that the video compressed data size or the video transmission speed is reduced accordingly to a ratio of ? (¼ in the case of RGBW of 2×2 matrix arrangement because white (W) can be regenerated from the corresponding R, G, B), thus storage memory and transmission bandwidth can be reduced considerably without degrading the visual perception of the video quality on the proprietary VP display.
