An image processing apparatus includes: a light source to irradiate an object with at least invisible light: an image sensor having sensitivity to a visible light wavelength range and an invisible light wavelength range: an image processor to generate an image according to image information that is output by the image sensor: a switching unit to switch the image processor to a single-color image generation mode in which a single-color image is generated. the single-color image being an image of a single color: and a controller to control the switching unit to switch the image processor to the single-color image generation mode in response to selection of an operating mode in which the invisible light is emitted.

An image processing device includes a distance image generation circuit configured to generate a distance image, a grouping process circuit configured to generate grouping information, and an object recognition process circuit configured to perform an object recognition process based on the grouping information. The grouping information is generated by correcting a result of a first grouping process based on a result of a second grouping process. The first grouping process is based on distance information included in the distance image. In the second grouping process, the grouping process is performed such that when a value of a color difference between two pixels of a captured image that are adjacent to each other is equal to or smaller than a predetermined value, the two pixels belong to the same group.

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for providing content to user devices. One of the methods includes receiving user generated content from a user device; identifying an image associated with the user; identifying one or more key colors from the image; generating a gradient based on one of the one or more key colors; and generating content for delivery to user devices using the user generated content, the image, and the generated gradient.

Disclosed are systems and techniques efficient color conversion. The techniques include receiving a first lookup table (LUT), a corresponding first range, a second LUT, and a corresponding second range. The first range is less than the second range. The techniques include receiving, from a first computer system component, first color data of a first color space. The techniques include, responsive to determining that the first color data is within the first range corresponding to the first LUT, converting the first color data of the first color space to second color data of a second color space using the first LUT. The techniques include providing, to a second computer system component, the second color data of the second color space.

A video processing method and apparatus, a device and a medium are provided. The video processing method includes: decoding a non-linear video to acquire a corresponding non-linear video frame; processing the non-linear video frame to generate a corresponding linear video frame; acquiring a target linear effect resource having a color space consistent with a color space adopted by the linear video frame; and fusing the linear video frame and the target linear effect resource to generate a linear effect video frame. The color accuracy of the generated linear effect video frame is ensured, the added effect resource is more natural and the realism of the generated linear effect video frame is improved.

Disclosed are systems and techniques for image demosaicing with minimal artifacts. The techniques include computing a color value within a first color space for a first pixel of a plurality of pixels based at least on color values within the first color space of a first group of neighboring pixels of the first pixel and computing a first chrominance value within a second color space for the first pixel based at least on the computed color value within the first color space. The techniques include computing a luminance value within the second color space for the first pixel based at least on the first chrominance value within the second color space and converting the luminance value within the second color space and the first chrominance value within the second color space to an output pixel value within a third color space.
