Patent number: 8687014Abstract: A process and circuit for blending a foreground image (B) with a background image (A), said foreground and background images being arranged in pixels and having color representations (R, G, B). The foreground foreground image (A) has a transparency parameter (T(x,y)) in accordance with a so-called alpha plane representative of the transparency profile to apply to the foreground image. The process involves the steps of: -applying a dithering method on said alpha plane in order to convert said transparency parameter (T) into a one-bit transparency parameter (T?); -use said one-bit transparency parameter (T?) for controlling a multiplexing unit having two inputs respectively receiving the foreground image (A) and the background image (B). In one embodiment, the one-bit transparency parameter T? into the two extreme values of a range of continuous values, for instance coded on 8 bits.Type: GrantFiled: December 29, 2009Date of Patent: April 1, 2014Assignee: ST-Ericsson SAInventors: David Coupe, Gilles Spinelli

Patent number: 8687010Abstract: Arbitrary size texture palettes. A texture palette storage embodied in a computer readable medium is provided. The texture palette storage is partitioned into texture palette tables of arbitrary size. Texel data is stored for each of the texture palette tables in the texture palette storage. Another aspect is a palette memory that receives a texture index value of y-bits. The palette memory comprises subtables of different length. Each sub-table has a range with a start address and a length. The start address is a multiple of m. Each range is of a length addressable by y-bits. The palette memory also includes a sub-table index value of x-bits.Type: GrantFiled: May 14, 2004Date of Patent: April 1, 2014Assignee: Nvidia CorporationInventor: Jim Battle

Patent number: 8605111Abstract: Disclosed is a method for correcting color in a portable image projector in consideration of an effect of a background color when the portable image projector projects images. The method corrects the effect of the background color to be projected, using color constancy technique, and thereby represents high-quality image which can be projected on a white screen. The method includes the steps of determining if a background color exists on a projection screen using a portable camera, converting the size of a mask image in order to connect a spatial position of an original image and an image photographed by a camera, correcting brightness of the mask image in order to correct non-homogeneity of the brightness of the projected image due to the distribution of different brightness values of the background color, and correcting the background color in order to correct color distortion of the image projected in different colors on the background color.Type: GrantFiled: September 26, 2007Date of Patent: December 10, 2013Assignees: Samsung Electronics Co., Ltd., Kyungpook National University Industry-Aademic Cooperation FoundationInventors: Jae-Won Moon, Sung-Dae Cho, Young-Min Jeong, Jong-Man Kim, Yun-Je Oh, Young-Ho Ha, Chul-Hee Lee, Chang-Hwan Son, In-Su Jang
