Abstract: Optics systems presented are arranged as high-performance imagers particularly characterized by their exceptional compactness in view of image quality. A plurality of lens and let's and or doublets are configured to cooperate with related mount systems optimized for compactness. To achieve very high resolution imaging despite somewhat abbreviated compound lens design, these systems include use of lens array elements proximate to an imaging plane. So placed lens array devices may be designed with lens elements which invariably operate on incident wave planes with radial dependence. That is, the focusing strength of lenses from which these lens arrays are comprised may depend upon its distance from system optic axis. This enables an imaging correction function that counters distortion and other undesirable imaging errors typically present in a simplified compound lens systems.

Abstract: Systems are presented with special mechanical means to switch a set of lens elements to form a compound lens from a storage position to an imaging position. In the storage mode, these arrangements offer highly efficient space saving schemes suitable for use in application where space is a premium. In the imaging mode, a plurality of lens singlets are brought together on a common imagine axis whereby they operate to form very high quality images at a single image plane. Singlet lenses are held in a lens mount device of a disk element. A plurality of similar cooperating disk elements move against adjacent coupled disks to cause well-regulated desirable motion and positioning. Specifically, portions of the disk include a cam system which permits smooth movement as disk elements are counter rotated with respect to each other thus driving the preferred positioning.

Abstract: A device having a camera module, installed on the housing of the device such that the position of the camera module relative to the housing can be changed. One of the positions, an exposure position, involves optical elements which are oriented so as to be able to project light onto light-sensitive elements in order to produce an image on one or more sensors. A second position involves being flush against, and as close as possible to, the housing of the mobile device, by means of folding. The overall thickness of the camera module is structurally limited by the thickness of the thickest optical or light-sensitive element. The device contains structural elements for processing a digital representation of an image obtained from the light-sensitive elements. The camera module includes optical elements in the form of a set of thin lenses and/or mirrors, and one or a plurality of light-sensitive elements, namely sensors consisting of light-sensitive pixels.

Abstract: A digital method for removing optical aberrations from the image is disclosed. The method includes the initial profiling of an optical system and using the obtained information to correct the optical aberrations introduces to the image by the same or identical optical system.

Abstract: A collapsible imaging system having a compound lens and a lenslet array, which is coupled with an image sensor. The collapsible imaging system can be transitioned between the imaging and storage modes by moving compound lens elements along the optical axis and off the optical axis of the system. In the storage mode, the compound lens elements are tightly packed in a flat volume.

Abstract: A method of processing of photo and video images is disclosed which searches for a minimum of cost functions carried out at an N-number of image detail levels, from coarser to finer, and at each image detail level the image is divided into regions; each region is assigned a single segmentation value by a ?-number of successive iterations. The value of the cost function for the seams at the region boundaries is calculated with different types of image segmentation, and for every region a segmentation value is chosen which minimizes the sum of the cost functions of the seams and data. The technical result is the segmentation of an image with little use of the memory resources of a mobile device while maintaining both resistance to image noise and operating speed.

Abstract: A method and a digital filter, for use with photo and video images, includes using a camera or video camera equipped with sensors and an electronic shutter to capture a plurality of frames of low resolution and producing one frame of high resolution. A plurality of frames are exposed. Initial images are in the form of a continuous sequence of frames with high-speed capture. The frequency of the frames is inversely proportional to the magnitude of that part of the light-sensitive region of the sensor that is being scanned. The initial images are aligned and an enhanced image is produced. The enhanced image is filtered using a nonlinear filter which includes a neural network that is pretrained using a test image including radial and sinusoidal test charts, as well as reference points.

Abstract: A method for producing high-quality photographic images in low-light conditions and in the absence of large-aperture optics. The method includes, upon photographing, first obtaining a plurality of frames of the image with exposures which either partially overlap in time or with an insignificant pause between them. The best result can be obtained in the case when the pause between the exposures represents less than 1/20 of the overall exposure time. The method further includes separating out the initial images from a group of exposures and filtering the images having the smallest exposure interval using the images having the largest exposure interval. The final image is obtained by combining initial images having different exposure intervals from the same group.
