An imaging device according to the present invention includes multiple pixels arranged in a row direction and a column direction, which are orthogonal to each other. The multiple pixels include distance measurement pixels each including multiple photo-electric converters arranged so as to be adjacent to each other in the row direction. When M and N denote integers not smaller than one, the pixels are arranged at positions shifted in the row direction for every M-number rows by an amount corresponding to a half of the pixel, color filters are arranged in the row direction in an array of N-number columns per cycle, and the color filters are arranged in the column direction in an array of 2MN-number rows per cycle.

A multi-color system for optically inspecting a surface of a specimen includes a multi-wavelength led array to illuminate the specimen with a multi-color light pattern including simultaneously emitted spatial intensity color image patterns, each of which has first areas in which light is emitted with a first light intensity and second areas in which the light is emitted with a second light intensity, the first light intensity being higher than the second light intensity, and corresponding first and second areas in each of the simultaneously emitted spatial intensity color image patterns being phase-shifted relative to each other. A multi-color sensor captures each of the simultaneously emitted spatial intensity color image patterns reflected from the surface of the specimen in a single wavelength-multiplexed sensor image, and a data processing apparatus in communication with the multi-color sensor determines properties of the surface based on an evaluation of the single wavelength-multiplexed sensor image.

An image signal processor (110) according to an embodiment inputs, as an input image, a mosaic image in which pixel blocks each of which is formed of a plurality of pixels of the same color sharing one lens (40) are arrayed. The image signal processor performs interpolation processing on the entire surface of the input image based on a pixel signal of a pixel of a predetermined color included in the input image to generate a first image signal. The image signal processor generates a second image signal, which has a difference based on a relative position of a pixel of interest with respect to the lens and has a lower resolution than the first image signal, based on the input image. The image signal processor generates a conversion pixel whose position after conversion corresponds to a position of the pixel of interest based on a component obtained by subtracting the second image signal from the first image signal.

The present technology relates to an imaging element, an imaging apparatus, and electronic equipment which are capable of accurately detecting phase difference. The imaging element includes a first light-receiving part that receives incident light entering through a first on-chip lens, a first phase detecting pixel which is placed between the first on-chip lens and the first light-receiving part and which has a shading film to limit an amount of light reaching the first light-receiving part, and a second phase detecting pixel which has a second light-receiving part to receive incident light entering through a second on-chip lens, with the second light-receiving part being divided into a plurality of light-receiving regions. The technique disclosed herein is applicable to imaging apparatuses having the autofocusing function.

A method includes capturing, by a camera disposed behind a display panel of an electronic device, an original image through a semi-transparent pixel region of the display panel. The original image includes one or more color components. The method further includes determining, for a plurality of pixel regions of the original image, a point spread function (PSF) for each of the one or more color components. The method further includes performing, for the plurality of pixel regions of the original image, a deconvolution of each of the one or more color components of the original image based at least in part on their respective PSFs. The method thus includes generating a reconstructed image corresponding to the original image based on the deconvolutions of the one or more color components of the plurality of pixel regions of the original image.

The present invention relates to an error correction unit for a time slice image. The present invention comprises: a stand having a length corresponding to the height of an object and standing upright; and a plurality of marker members, installed on the stand, for indicating a plurality of reference positions for setting an offset reference value, and providing the same shape in all directions. The present invention can readily set the offset reference value through the plurality of reference positions.

A system and method for generating high resolution images using a plenoptic camera, is provided. In one embodiment, the comprises capturing a first set of images in a first unexcited state of operation by using a birefringent medium disposed between a main lens and an array of lenses having a plurality of apertures. Each pixel of the first set of images is then mapped to a first set of apertures. The first unexcited state is then caused to become a second excited state by applying a voltage across said birefringent medium. A second set of images are captured in the second excited state and a second set of pixels of the second image is mapped to a second set of apertures. A value is calculated for each first and second set of images and the value associated with said first set of images is subtracted from at least two times the value calculated from said second set of image.

Systems and methods for improving target object visibility in captured images can include an imaging sensor for mounting on an aircraft at a fixed position and orientation. A predetermined portion of the aircraft can appear as a region of interest (ROI) at a predefined location across images captured by the imaging sensor. A processor can receive a first image signal captured by the imaging sensor and corresponding to a first image that includes the ROI. The processor can determine a first image intensity range of the ROI in the first image and gain and offset values for modifying the first image or a subsequent image. The processor can cause a second image signal, received from the imaging sensor, to be amplified according to the gain and offset values and cause the region of interest in a second image to have a second image intensity range different from the first image intensity range.

An imaging sensor includes a color filter, and DBPF that has a transmission characteristic in a visible-light band, a blocking characteristic in a first wavelength band adjacent to a long-wavelength side of the visible-light band, and a transmission characteristic in a second wavelength band that is a part of the first wavelength band. A transmission characteristic of DBPF and a transmission characteristic of each filter part of the color filter are set in such a manner that the second wavelength band of DBPF is included in a third wavelength band that is a wavelength band in which transmittance of the filter parts in colors is approximate to each other on a long-wavelength side of the visible-light band and a fourth wavelength band that is a wavelength band in which a filter part for infrared light has a transmission characteristic.

In a line sensor including color filters that are periodically disposed in a light-receiving-element row, a problem called a mixture of colors occurs. A mixture of colors occurs when light that has been transmitted through a color filter differing from a color filter corresponding to a light receiving element is incident upon the light receiving element.

In a CMOS sensor 107 including a light-receiving-element row in which a plurality of photodiodes 1204 are disposed side by side in a main scanning direction and a plurality of color filters 1202 that are disposed in correspondence with the plurality of photodiodes 1204, the center of each color filter 1202 is displaced in a direction of the center of the light-receiving-element row from the center of the photodiode 1204 corresponding to the color filter.
