  • Patent number: 11022858
    Abstract: A disclosed apparatus includes a plurality of camera units. Control logic, operatively coupled to each camera unit, is operative to perform a parallax operation using at least two image frames from at least two camera units to determine a common focus distance, subsequent to completing independent auto-focus operations and respective lens position adjustments for the at least two camera units. The control logic provides a control signal to at least one of the camera units to adjust its actuator to adjust lens position in response to the determined common focus distance. A test procedure is used to map focus distance to lens position for each camera unit and to generate a lookup table. The control logic uses the lookup table unique to each camera unit to adjust the lens settings according to the determined common focus distance. The parallax operation is iterated until the common focus distance converges.

  • Patent number: 10735711
    Abstract: A method, system, and computer program product for generating a three-dimensional image from a captured two-dimensional image. The method includes capturing, via a wide-angle camera sensor of an image capturing device, a two-dimensional image of a scene. The method further includes determining depth information of the scene. The method further includes generating, from the depth information, a depth map that depicts a depth of the scene in a third dimension. The method further includes generating a wide-angle three-dimensional image by merging the depth map and the two-dimensional image.

  • Patent number: 9741117
    Abstract: An apparatus includes a plurality of camera units where each camera unit has a lens, a sensor that can detect at least three colors, and camera unit calibration data for each camera unit is stored in non-volatile, non-transitory memory. The apparatus also includes multi-camera auto white balance synchronization logic that is operatively coupled to each camera unit. The multi-camera auto white balance synchronization logic is operative to determine common white balance results based on the camera unit white balance results per frame and the camera calibration data. The common white balance results are provided to image signal processing pipelines such that a merged frame can be obtained by combining the frames of each camera after performing white balance and color correction using the common white balance results.

  • Patent number: 8018504
    Abstract: Noise is reduced in a digital image generated by an imaging device utilizing information which specifies noise level as a function of position for the digital image. A noise reducing algorithm is applied to the digital image while one or more parameters of the noise reducing algorithm are varied. The one or more parameters are varied as a function of field position in the digital image based on the obtained noise level as a function of field position. In this way, noise is substantially reduced and is spatially equalized in the digital image.

  • Patent number: 7683950
    Abstract: A method, and digital capture apparatus for use therewith, is described for correcting a channel dependent color aberration in a digital image, where the digital image is composed of a plurality of color channels. The method includes capturing an image comprising the color channels, where one of the color channels is a blurred color channel due to a channel dependent color aberration affecting that channel. Then, one of the other color channels, other than the blurred color channel, is used as an indication of an aim sharpness, and the sharpness of the blurred color channel is adjusted, at least partially, toward the aim sharpness.

  • Publication number: 20090096915
    Abstract: A filter system for an imaging apparatus including a high resolution mode of operation and a low resolution mode of operation is provided. The filter system includes a low pass filter associated with an optical path of the imaging apparatus. The low pass filter is moveable into the optical path of the imaging apparatus when the imaging apparatus is in the low resolution mode of operation and is moveable out of the optical path of the imaging apparatus when the imaging apparatus is in the high resolution mode of operation.

  • Patent number: 7443431

  • Publication number: 20080159644
    Abstract: Blur is reduced in an image generated by an imaging device by determining values of one or more atmospheric variables for the image, the one or more atmospheric variables characterizing conditions under which the image is generated. With these values, a sharpening filter is determined for the image. The sharpening filter is derived from a modulation transfer function of the imaging device at conditions characterized by the values of the one or more atmospheric variables determined for the image. The sharpening filter is subsequently applied to the image.

  • Patent number: 7092017
    Abstract: CMOS imagers can possess higher levels of imager noise than their predecessors, CCDs. This noise can be of the form of temporal variation and fixed pattern. The fixed pattern component of this noise can be removed, which is known already in the art. The invention in this disclosure is that proper correction can be developed for all imager conditions (imager integration time and imager temperature) using a single FPN (fixed pattern noise) dark map, a single FPN PRNU (pixel response nonuniformity) map, imager integration time and imager temperature. Without this invention, a dark frame capture and a flat field capture (integrating sphere), are required before every image capture, a practical impossibility in typical picture taking.

  • Patent number: 6628329
    Abstract: Images are sharpened and corrected for position dependent blur by providing a sharpening function which is adapted to operate upon signals corresponding to a selected number of pixels, providing a plurality of values which are a function of the position dependent blur; and applying the plurality of values to the sharpening function to modify the sharpening function so that after the modified sharpening function is applied to the image, a sharpened image will be provided which has been corrected for the position dependent blur.
