20080225135Imaging Device Element - characteristic are improved. An imaging device having a hybrid RGBYC color filter using a primary color system RGB filter and a complementary color system YC filter is composed. Four G filters that directly relate to resolution and that is close to a luminance signal that human eyes sense are arrayed in a checker shape so that the number of the G filters is four times larger than the number of filters of each of the other colors. An array shown in FIG. 09-18-2008
20080240203Method of and apparatus for analyzing noise in a signal processing system - A fast accurate multi-channel frequency dependent scheme for analyzing noise in a signal processing system is described herein. Noise is decomposed within each channel into frequency bands and sub-band noise is propagated. To avoid the computational complexity of a convolution, traditional methods either assume the noise to be white, at any point in the signal processing pipeline, or they just ignore spatial operations. By assuming the noise to be white within each frequency band, it is possible to propagate any type of noise (white, colored, Gaussian, non-Gaussian and others) across a spatial transformation in a very fast and accurate manner. To demonstrate the efficacy of this technique, noise propagation is considered across various spatial operations in an image processing pipeline. Furthermore, the computational complexity is a very small fraction of the computational cost of propagating an image through a signal processing system.10-02-2008

20090160988DRIVE METHOD FOR SOLID-STATE IMAGING DEVICE, SOLID-STATE IMAGING DEVICE, AND IMAGING APPARATUS - A solid-state imaging device having: (a) a pixel array with an oblique pixel pattern in which pixels are obliquely disposed, an odd-numbered row vertical signal line in an odd-numbered row vertical signal line group being connected to each column of odd-numbered row pixels and an even-numbered row vertical signal line in an even-numbered row vertical signal line group being connected to each column of even-numbered row pixels; (b) a row selector for separately selecting an odd-numbered row and an even-numbered row of the oblique pixel pattern; (c) an odd-numbered row column processing circuit group including column processing circuits and connected to the odd-numbered row vertical signal line group, for adding signals of the odd-numbered row pixels between columns; (d) an even-numbered row column processing circuit group including column processing circuits and connected to the even-numbered row vertical signal line group, for adding signals of the even-numbered row pixels in pixel columns; and (d) a column selector for selecting the column processing circuits of the odd-numbered row column processing circuit group and the column processing circuits of the even-numbered row column processing circuit group.06-25-2009
20090213251IMAGING APPARATUS AND IMAGING DEVICE - An imaging device having five color filters. The five color filters include three color filters of a R (red) filter, a G (green) filter, and a B (blue) filter of a primary color system and two color filters of a Y (yellow) filter and a C (cyan) filter of a complementary system. The G filter has a checker shape G filter so that the space information of green is obtained four times larger than that of each of the other colors.08-27-2009
20100231745IMAGING DEVICE AND SIGNAL PROCESSING METHOD - The present invention provides an imaging device that generates, for, each of a red color, a green color, and a blue color, an image signal having pixels arranged adjacent to each other in a two-dimensional array, including a red color imaging element that senses incident light to output a red color signal (09-16-2010
