Abstract: An imaging system is configured to identify an object represented by a plurality of preliminary images. The preliminary images are each associated with a different camera imaging channel, and include different image information. An object distance is determined based on the difference in preliminary image information. An object shift is determined based on the object distance and a pre-determined relationship between object shift and object distance. The object shift is applied to the portions of one or more preliminary images representing the object to form shifted preliminary images, and the shifted preliminary images are combined to form a final image.

Abstract: Spatial resolution can be improved in multi-lens digital cameras. Each lens can have the same or similar field of view, but can be associated with different geometric distortions defining, for example, a magnification at various field of view portions. A final image can be generated based on an initial image captured by each lens. Luminance information from the magnified portions of the initial images can be combined to form final image luminance information. Chrominance information from the initial images can be combined to form final image chrominance information. The final image can be generated based on the final image luminance information and the final image chrominance information.

Abstract: Imaging apparatus includes an image sensor, which is adapted to generate an input image in response to optical radiation. A processing engine is configured to apply a digital filter, having a kernel width greater than five pixels, to the input image to generate a filtered image. An optical assembly is arranged to focus the optical radiation onto the image sensor with a point spread function such that no more than a first threshold percentage of energy emitted from a point object and focused by the optical assembly falls within a first region of the image sensor having a first width five times the pitch of the image sensor, while at least a second threshold percentage of the energy emitted from the point object and focused by the optical assembly falls within a second region, which contains the first region and has a second width corresponding to the kernel width.

Abstract: One or more objects of interest from a scene are selected. Depth information of the one or more objects is calculated. Additionally, depth information of the scene is calculated. The calculated depth information of the one or more objects is compared with calculated depth information of the scene. Based on the comparison a blur is applied to an image that includes the scene.

Abstract: Spatial resolution can be improved in multi-lens digital cameras. Each lens can have the same or similar field of view, but can be associated with different modulation transfer functions defining varying sharpness based on location within the field of view. The image information received from each lens can be combined to form an image based on the sharpness of the image information received from each lens.

Abstract: The luminance information of an image captured by a multi-lens camera system can be improved by selecting a luminance information source for each portion of the captured image. Each lens of the camera system can capture an initial image. For each portion of a final image, a corresponding initial image portion can be selected as the luminance information source. The portions of the final image and initial images can be pixels, groups of pixels, or other image portions. The luminance information from the selected initial image portions is combined to form final image luminance information. Chrominance information can also be selected from the initial images to form final image chrominance information, and the final image chrominance information and the final image luminance information can be combined to form a final image.

Abstract: The exposure of pixel lines in one or more image sensor regions is substantially synchronized. Each image sensor region is associated with a different lens in a multi-lens camera system. For a first pixel line in a first image sensor region and a second pixel line in a second image sensor region corresponding to the same portion of a field of view, the first pixel line and the second pixel line are sequentially or substantially simultaneously exposed. After exposing the first pixel line and the second pixel line, image information associated with the exposures is combined and output on the same readout line.

Abstract: A method and system are for measuring and correcting shifts in the boresight, effective focal length, and focus of an optical system that are caused by temperature variations. The method can be used for systems which can be expected to operate in situations where the temperature variations are large, e.g. a FLIR system of a fighter plane, and also where the temperature variations can be very small however high accuracy is needed. The invention is based on placing radiation emitting sources before and as close as possible to the first optical element of the optical system and measuring the thermally induced shifts of the locations of the images of the radiation emitting sources on the surface of the detector of the optical system.
