摘要： A light sensitive imaging system adapted for determining a crosstalk value of an OB (optically black) pixel arranged in a pixel array, the system comprising at least one image sensor comprising at least one pixel array, and processing means. The pixel array comprises a plurality of color channel pixels (CP 1 , … ,CP n ) and at least one OB pixel (OB 1 , … ,OB n ). The processing means is adapted for detecting an intensity value (IVOB 1 ) of a color channel of an OB pixel (OB 1 ), detecting an intensity value (IV 1 ) of a neighboring color channel pixel (CP 1 ), and calculating a crosstalk value (CV 1 ) for the OB pixel (OB 1 ) based on the intensity values (IVOB 1 ; IV 1 ).

摘要： A system for optimized image stabilization, wherein a focus lock of a camera unit having an image stabilizer is detected (415) and in response to this detection, the image stabilization is suspended (425). A target position for the image stabilizer is determined (435) and the image stabilizer is driven to the target position (440). In response to a detected shutter release (445), the image stabilization is continued (455).

摘要： A method and apparatus are disclosed for digital camera image error detection, especially for fixed pattern noise detection (312) and elimination (314). Images cast onto an image sensor through a lens system are varied using a force element when the lens system is optically connected to the image sensor so that the image sensor takes a blurred reference image. The image sensor comprises a plurality of image capture pixels, each image capture pixel being configured to produce a pixel output signal indicative of the intensity of light that falls on the image capture pixel in question at a given frequency range. Faulty image capture pixels are detected by finding pixel values that differ significantly (312) from neighboring pixel values in the blurred reference image. An indication of the faulty or defective pixels is stored in a memory (322). The blurred reference image may be formed by defocusing or by optically dithering (306) the image falling on the image sensor.

摘要： A color filter apparatus includes a two-dimensional array of an N x M pattern of light sensitive elements with a plurality of I x J pixel groups. A 2 x 2 pixel group includes a first color filter of a first color that is a primary color and a second color filter of a second color that consists of green content and one other color. When the first color is green, the second color includes another primary color, but not a third primary color. When the first color is not green, the second color includes the first color.

摘要： A color filter apparatus includes a two-dimensional array of an N x M pattern of light sensitive elements. A 2 x 2 pixel group of the N x M pattern includes at least one pixel of a first color having a narrow spectrum response, aligned on a diagonal of the 2 x 2 pixel group. At least one pixel of a second color having a wide spectrum response is aligned on a second diagonal in the 2 x 2 pixel group. The second diagonal in the 2 x 2 pixel group is perpendicular to the first diagonal. An arrangement of at least one pixel of the first color in one 2x2 pixel group of the N x M pattern is disposed perpendicularly to an arrangement of at least one pixel of a first color in another 2 x 2 pixel group of the N x M pattern.
