Abstract: A color filter apparatus includes a two-dimensional array of an N×M pattern of light sensitive elements with a plurality of I×J pixel groups. A 2×2 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.

Abstract: In one example, at least a portion of a digital raw image frame captured by a digital image sensor is accessed. The accessed at least a portion of the digital raw image frame is de-noised without substantially modifying defective pixel values when present. In response to determining that at least one image frame pixel in the de-noised at least a portion of the digital raw image frame has a defective pixel value: the locations of each of the at least one image frame pixel having a defective pixel value are detected, and each defective pixel value in each detected location is corrected in the de-noised at least a portion of the digital raw image frame or the originally accessed at least a portion of the digital raw image frame.

Abstract: An apparatus including a plurality of sensor elements, configured in an arrangement having a repeating pattern of sensor elements, the plurality of sensor elements including first monochromatic sensor elements configured to sense visible light of a first color; second monochromatic sensor elements configured to sense visible light of a second color; and panchromatic sensor elements configured to sense visible light of at least the first color and the second color, wherein the majority of the plurality of sensor elements are panchromatic sensor elements.

Abstract: In one example, luminance information related to a digital raw image frame captured via a color filter array is obtained. Chrominance information related to the digital raw image frame is obtained. The obtained luminance information and chrominance information are downscaled to a target resolution, such that one of pixel data of the captured digital raw image frame and the obtained chrominance information has been demosaiced before the downscaling. The downscaled chrominance information is reverse-demosaiced.

Abstract: An image sensor system comprises a plurality of image sensing pixels which are arranged in lines. Control circuitry in the image sensor system is configured, when capturing a single image, to set an exposure time for the image sensing pixels in a line such that a first group of pixels in the line has a first exposure time and a second group of pixels in the same line has a second exposure time.

Abstract: A system for optimized image stabilization, wherein a focus lock of a camera unit having an image stabilizer is detected and in response to this detection, the image stabilization is suspended. A target position for the image stabilizer is determined and the image stabilizer is driven to the target position. In response to a detected shutter release, the image stabilization is continued.

Abstract: An apparatus, method and computer program, in which there is provided an apparatus with a body, which apparatus has a set of camera modules mounted on the body, each camera module configured to take images with a first field of view and an adjustment mechanism configured to move the camera modules between a first configuration and a second configuration. In the first configuration, each camera module shares a substantially common field of view that covers a first view area. In the second configuration, the fields of view of the camera modules collectively form a second view area that is continuous and covers a second view area. A zoom-in image is formed in the first configuration using super-resolution combining of the images taken by the camera modules.

Abstract: A method for providing an output image based on an input image, the method comprising determining a location of an output pixel with respect to an input image, determining values of elements of a filter array such that the effective width of the filter array depends on the density of exposed input pixels within the input image, and determining the value of the output pixel by performing a sum-of-products operation between non-zero values of the elements of the filter array and the values of input pixels of the input image located at respective positions, when the filter array is superimposed on the input image such that the center of the filter array corresponds to the location of the output pixel.

Abstract: An improved system and method for providing information concerning the level of focus of objects appearing on a viewfinder for a digital camera system. The present invention analyzes a plurality of objects or regions of an image that is being shown to a user through a viewfinder of an electronic device. The system creates an overview map that matches the objects within the image, and colors are applied to objects within the overview map, representing the focus quality levels of the respective objects. The overview map is superimposed over the image, providing the user with information concerning the relative focus quality of the respective objects.
