| 20080260291 | Image downscaling by binning - The specification and drawings present a new method, apparatus and software product for image binning (downscaling) according to a predetermined procedure for a pre-selected color arrangement (e.g., a Bayer arrangement) by substantially maintaining a phase of channels (represented by selected colors) for reducing/elimination of artifacts in images taken by an electronic device. Several binning or scaling modes where the center points of each binned (e.g., averaged) pixel are arranged in the pre-selected color arrangement and maintain the phase of the channels are described. | 10-23-2008 |
| 20080297816 | Method and system for black-level correction on digital image data - The black level in raw image data captured from an image sensor does not always stay fixed at a constant level, but may change as a function of the analog gain and exposure time and may vary from one spatial location of the pixels to another. To carry out black-level correction on the raw image data, the black level of each of the color components is measured at one or more sampling locations. A look-up table is generated based on the measured black levels and a computation module is used to carry out black-level correction based on the information stored in the look-up table. The look up table may have information indicative of the analog gain level and the exposure time and the variations of black-levels in different spatial locations. | 12-04-2008 |

| 20100321511 | Lenslet camera with rotated sensors - At a digital imaging system, a first set of samples of a scene are digitally captured with a first array of image sensing nodes while simultaneously a second set of samples of the scene are digitally captured with a second array of image sensing nodes. Image sensing nodes of the second array are oriented in a rotated position relative to the image sensing nodes of the first array. The first and second sets of samples are integrated with one another while correcting for the rotated orientation of the image sensing nodes of the second array relative to the image sensing nodes of the first array, and from that integration is output a high resolution image. In specific embodiments, there may be additional arrays of image sensing nodes, different arrays may sample different size portions of the scene, and be also rotated relative to other sensing node arrays. | 12-23-2010 |
| 20100321542 | Gradient color filters for sub-diffraction limit sensors - An apparatus includes an array of sub-diffraction limit-sized light receptors formed in a substrate having a light receiving surface. Each receptor is configured to output an n-bit element and to change state based on the absorption of at least one photon (n is an integer >0). The apparatus includes an optical filter structure disposed over the light receiving surface, the structure having an array of filter pixels, each having an associated passband spectral characteristic. A data element obtained from the array of receptors is generated from a combination of a plurality of the n-bit elements output from a plurality of light receptors that underlie filter pixels having at least two different passband spectral characteristics. The filter pixels having at least two different passband spectral characteristics form a gradient filter wherein bandpass regions increase when moving from a central region of the gradient filter towards an edge region. | 12-23-2010 |
| 20100328456 | Lenslet camera parallax correction using distance information - An apparatus, method and software construct an image of a scene by determining distance information to an object in a scene; and using the distance information to correct parallax error when combining at least two images of the object which were captured from different viewpoints. A single image of the scene from the combining is then output, with the object corrected for parallax error. In one embodiment the distance information is input from an autofocus mechanism of a multi-camera imaging system, and in another the distance information is derived from one of an object recognition algorithm or a scene analysis algorithm. The two (or more) images that are combined are captured preferably on different lenslet cameras of the same multi-camera imaging system, each of which sees the object in the scene from a different viewpoint. | 12-30-2010 |
