An imaging system serving as an image generation device is provided with: a random optical filter array that has a plurality of types of optical filters and a scattering unit; photodiodes that receive light transmitted through the random optical filter array; an AD conversion unit that converts the light received by the photodiodes, into digital data; and a color image generation circuit that generates an image, using the digital data and modulation information of the random optical filter array, in which the scattering unit is located between the plurality of types of optical filters and the photodiodes, and in which the scattering unit includes a material having a first refractive index, and a material having a second refractive index that is different from the first refractive index.

An image sensor can be present within an optical capture device. Two lenses that capture and direct light from a real world environment upon the image sensor. The image sensor converts light from the real world environment into electronic signals. A separator can be positioned between optical pathways of light from the lenses. The separators can absorb light from a region surrounding the image circle to prevent optical distortions from the image circles which are in close proximity to each other.

An image processing method is provided. The method is configured to process the color-block image output by the image sensor. The high-frequency region of the color-block image is determined. A part of the color-block image within the high-frequency region is converted into a first image using a first interpolation algorithm. A part of the color-block image beyond the high-frequency region is converted into a second image using a second interpolation algorithm. The complexity of the second interpolation algorithm is less than that of the first interpolation algorithm. The first image and the second image are merged into a simulation image corresponding to the color-block image. An image processing apparatus and an electronic device are provided.

An image sensor includes a substrate, a first set of sensor pixels formed on the substrate, and a second set of sensor pixels formed on the substrate. The sensor pixels of the first set are arranged in rows and columns and are configured to detect light within a first range of wavelengths (e.g., white light). The sensor pixels of the second set are arranged in rows and columns and are each configured to detect light within one of a set of ranges of wavelengths (e.g., red, green, and blue). Each range of wavelengths of the set of ranges of wavelengths is a subrange of said first range of wavelengths, and each pixel of the second set of pixels is smaller than each pixel of the first set of pixels.

According to one embodiment, a processing device includes a memory and a circuit coupled with the memory. The circuit acquires a first image of a first color component and a second image of a second color component. The first image has a non-point-symmetric blur function and captures a first object. The second image has a point-symmetric blur function and captures the first object. The circuit determines whether the first object is on a near side of a first position or on a deep side of the first position when viewed from a capture position based on the first image and the second image.

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 plurality of adjacent pixels is provided adjacently in a plurality of directions to a first pixel. A direction with a highest correlation is derived from signals of the plurality of pixels, and the direction with the highest correlation is reflected to interpolation processing to be performed on the signal of first pixel.

A plenoptic imaging device according to the invention comprises an image multiplier (130) for obtaining a multitude of optical images of an object or scene and a pick-up system (140) for imaging at least some of the multitude of images to a common image sensor (170) during the same exposure of the sensor.

An in-liquid state of a mobile device is detected by processing color components indicative of an intensity of the ambient light at different wavelengths and a pressure data indicative of ambient pressure. A first plausibility index indicates a likelihood of an air/liquid transition as a function of variations of at least two color components. A second plausibility index indicates a likelihood of an air/liquid transition as a function of variations of said ambient pressure. If both the first and the second plausibility indices indicate a likely air/liquid transition event, an in-liquid state signal is generated.

A system for multispectral imaging and ranging is provided. The system comprises at least one light illumination source, and a focal plane detector array configured to support both passive imaging and active imaging at multiple wavelengths. The focal plane detector array includes a plurality of pixels, wherein each of the pixels comprises a plurality of detectors. The detectors are configured to collect passive light to support passive imaging; collect retro-reflected light, transmitted by the at least one light illumination source, to support active illuminated imaging; and collect retro-reflected light, transmitted by the at least one light illumination source, to support active illuminated ranging.
