It is inconvenient for a user that a UI for inputting a virtual focus position at the time of refocus and a UI for inputting a focus position at the time of image capturing exist separately from and independently of each other. An image processing device comprising a generation unit configured to generate combined image data obtained in a case of capturing an image with a second set value different from a first set value used in capturing an image with an image capturing device by using a plurality of pieces of captured image data obtained by the image capturing device, wherein the image capturing device is capable of capturing image data from a plurality of viewpoint positions and includes an operation unit for setting a set value of an image capturing parameter, and wherein the first and second set values are set via the operation unit.

An iris recognition system may include an optical system having an intentional amount of spherical aberration that results in an extended depth of field. A raw image of an iris captured by the optical system may be normalized. In some embodiments, the normalized raw image may be processed to enhance the MTF of the normalized iris image. An iris code may be generated from the normalized raw image or the enhanced normalized raw image. The iris code may be compared to known iris codes to determine if there is a match.

Imaging apparatus includes imaging unit that captures a subject image while changing an in-focus position to generate a plurality of pieces of image data, image processor that synthesizes the plurality of pieces of image data generated by the imaging unit to generate still image data having a deeper depth of field than a depth of field of each of the plurality of pieces of image data, and controller that controls the image processor. Controller causes image processor to detect a main subject from an image indicated by one image data in the plurality of pieces of image data, determine a range for synthesizing the plurality of pieces of image data based on a position of the detected main subject, and synthesize pieces of image data focused within the determined range to generate the still image data.

A dual-aperture zoom digital camera operable in both still and video modes. The camera includes Wide and Tele imaging sections with respective lens/sensor combinations and image signal processors and a camera controller operatively coupled to the Wide and Tele imaging sections. The Wide and Tele imaging sections provide respective image data. The controller is configured to combine in still mode at least some of the Wide and Tele image data to provide a fused output image from a particular point of view, and to provide without fusion continuous zoom video mode output images, each output image having a given output resolution, wherein the video mode output images are provided with a smooth transition when switching between a lower zoom factor (ZF) value and a higher ZF value or vice versa, and wherein at the lower ZF the output resolution is determined by the Wide sensor while at the higher ZF value the output resolution is determined by the Tele sensor.

An image sensor included in a camera system comprises: a plurality of photodiodes for processing optical signals which have passed through a lens included in the camera system; and at least one mask, disposed on the top of at least one photodiode among the plurality of photodiodes, for enabling the optical signals which have passed through an inner region of the lens included in the camera system to enter the at least one photodiode.

A phase filter 101 is configured to comprise an annular structure rotationally symmetrical about an optical axis, each annular zone including a cross-sectional shape of substantially parabola for uniformly extending incident rays of light on a focal plane and letting the rays overlap with each other.

First and second images are captured at first and second focal lengths, the second focal length being longer than the first focal length. Element sets are defined with a first element of the first image and a corresponding second element of the second image. Element sets are identified as background if the second element thereof is more in-focus than or as in-focus as the first element. Background elements are subtracted from further analysis. Comparisons are based on relative focus, e.g. whether image elements are more or less in-focus. Measurement of absolute focus is not necessary, nor is measurement of absolute focus change; images need not be in-focus. More than two images, multiple element sets, and/or multiple categories and relative focus relationships also may be used.

An image processing apparatus includes a memory that stores instructions and a processor that executes the instructions to cause the image processing apparatus to function as a refocused-image generating unit generating a refocused image having a focus position changed by using image data including information indicating a direction and an intensity of a light beam entered from an object, and a depth-of-field setting unit setting a depth of field of the refocused image to be used for reproduction of a moving image based on a type of reproduction mode relating to the reproduction of the moving image.

Systems, devices, apparatuses and methods for high quality imaging of objects in a wide field of view and broad spectral band with extended depth of field in the object space and with a pre-set parallax for objects located at different distances, for applications in photography, machine vision, optical inspection, and cinematography. Extension of the depth of field is achieved by imaging with a multi-focus optical system that simultaneously forms in its common image plane the images of the illuminated objects, which are spaced apart along the optical axis. Multifocality of the optical imaging system can be achieved with one or more multi-focus lenses made of birefringent optical materials, optical crystals or polymers with stress-induced birefringence, designed so the optic axis of the birefringent material of each of the multi-focus lenses forms an angle with its optical axis in the range from approximately 10 to approximately 90. The aplanatic and achromatic optical design of the multi-focus optical system, high image quality in a wide field of view and broad spectral band over the entire extended common object field is achieved.
