The present disclosure relates to image capture systems and methods. The image capture method may include obtaining first color image data including color information with an infrared light source off. The image capture method may also include obtaining first luminance image data including luminance information with the infrared light source on. The image capture method may also include generating a first enhanced image based on the first color image data and the first luminance image data.

A device includes a digital camera positioned underneath a display of the device that captures images through the display. When capturing images using the digital camera, light emitted by the display can get into the digital camera, interfering with or corrupting the captured images. An enhanced output image is generated from a captured image that mitigates the interference from the display. The enhanced output image is generated, for example, by capturing a different calibration image for each pixel type (e.g., Red, Green, and Blue) included in the display. When an image is subsequently captured, an amount of color emitted by the pixels on the display for the currently displayed image is determined and one or more subtraction images are generated and subtracted from the captured image to mitigate the interference from the display.

Disclosed is an electronic device which includes a dynamic vision sensor that includes a first pixel sensing a change in light intensity and generates an event signal based on the sensed change in light intensity, an illuminance estimator that estimates illuminance of a light, and a time delay compensator that calculates a time delay between a first time at which the change in light intensity occurs and a second time at which the first pixel senses the change in light intensity, based on the illuminance of the light, and to compensate for the time delay.

Embodiments relate to processing of pixels captured by a quadra image sensor. A quadra image sensor includes a plurality of pixel tiles, each having a plurality of pixels corresponding to the same color. A lens shading correction (LSC) circuit receives, for each of a plurality of colors, a set of gain tables. Each gain table corresponds to a different channel associated with the color. Each gain table includes a set of gain values, each associated with a location. The LSC circuit determines a pixel gain value for each pixel in a pixel tile and scales the pixels in the pixel tile based on the determined pixel gain values.

An image processing apparatus includes a first acquisition unit that acquires a first pixel signal output from a first pixel, a second acquisition unit that acquires a second pixel signal output from a second pixel having a size smaller than that of the first pixel, a temperature detection unit that detects temperature; a composition gain determination unit that determines a composition gain corresponding to the detected temperature, and a composition unit that composes the first pixel signal and the second pixel signal multiplied by the composition gain.

An imaging device includes a pixel array, a first converter, a second converter, a first ramp signal generation circuit that is disposed closer to the first converter than to the second converter and supplies a first ramp signal to the first converter and the second converter, a first connection line having one end connected to an output terminal of the first ramp signal generation circuit and including a portion extending away from an input terminal of the first converter in a path from the one end to the other end of the first connection line, and a second connection line having one end connected to the other end of the first connection line and the other end connected to the input terminal and including a portion extending closer to the input terminal in a path from the one end to the other end of the second connection line.

There is provided an image processing apparatus, an image processing method, and a 3D model data generation method capable of easily adjusting an image capturing environment. The image processing apparatus includes an adjustment unit that adjusts camera parameters on the basis of a comparison result between a reference image based on images obtained by capturing images of a predetermined subject at different timings, and a captured image obtained by capturing an image of the same subject in a current environment. The present disclosure is applicable to, for example, an image processing system that performs image capturing for generating a 3D model.

An imaging system includes a processor, a memory, a visible light camera configured to record a first image of a scene, and an infrared camera configured to record a second image of the scene. The processor configured to execute instructions stored in the memory to input the first image and the second image into a neural network. The neural network relights the first image, based on characteristics of the second image, to correspond to an image of the scene under canonical illumination conditions.
