摘要： An image collection device for light splitting and fusion is provided. In the image collection device, a light splitter splits incident light into a visible light and a non-visible light; a visible spectrum imaging module performs photosensitive imaging according to the visible light split by the light splitter to form a first visible light image; a non-visible spectrum imaging module performs photosensitive imaging according to the non-visible light split by the light splitter to form a first non-visible light image; a registration unit performs position registration on the first visible light image and the first non-visible light image to obtain a target visible light image and a second non-visible light image; a pre-processing synthesizing unit performs brightness adjustment on the second non-visible light image to obtain a target non-visible light image; a fusion unit performs image fusion on the target visible light image and the target non-visible light image to obtain a fused image. By this solution, the color accuracy of the fused image can be ensured effectively.

摘要： Conversion between different projection formats of a 360-degree video may be performed in a uniform way. The geometric characteristics of the different projection formats may be considered when applying 3D-to-2D and 2D-to-3D mapping. Parameters reflective of the geometric characteristics of the different projection formats may be determined and used in the mapping and/or conversion. The parameters may include a normal vector that is perpendicular to a projection plane, a reference point in the projection plane, and/or unit vectors defined in the projection plane. An architecture with consolidated modules for handling the various projection formats may be provided.

摘要： Processing raw image data in a camera includes computing a luminance image from the raw image data, and computing a chrominance image corresponding to at least one of the sensor's image colors from the raw image data. The luminance image and chrominance image(s) can represent the same range of colors able to be represented in the raw image data. The chrominance image can have a lower resolution than that of the luminance image. A camera for performing the method is also disclosed.

摘要： An information processing device that includes an exposure control unit alternately repeats a first frame and a second frame. An infrared light irradiation control unit performs irradiation of infrared light in a predetermined infrared light irradiation period which is equal to or less than an aggregate period of the first frame and the second frame. An image signal acquisition unit acquires a first image signal which is the image signal in the first frame and a second image signal which is the image signal in the second frame. An extraction unit extracts a visible light intensity per unit time and an infrared light intensity per unit time from the first image signal and the second image signal. A generation unit generates an image signal corresponding to visible light and an image signal corresponding to the infrared light.

摘要： An image processing apparatus includes an image data acquiring means for acquiring image data that expresses a captured image of biological tissue, and a YC separation processing means for performing signal processing in which a luminance signal and color signals are generated based on the RGB signal of the image data. The ratio of the R component of the RGB signal included in the luminance signal is greater than the ratio of the G component and the ratio of the B component.

摘要： An image signal corresponding to infrared light is separated from an image signal corresponding to visible light, the visible light including an infrared light signal, even when imaging is performed while performing the infrared light irradiation. An exposure control unit alternately repeats a first frame in which an exposure time is set to a predetermined first exposure time and a second frame in which the exposure time is set to a second exposure time longer than the first exposure time. An infrared light irradiation control unit performs irradiation of infrared light in a predetermined infrared light irradiation period which is equal to or less than an aggregate period of the first frame and the second frame. An image signal acquisition unit acquires a first image signal which is the image signal in the first frame and a second image signal which is the image signal in the second frame. An extraction unit extracts a visible light intensity per unit time and an infrared light intensity per unit time from the first image signal and the second image signal. A generation unit generates an image signal corresponding to visible light and an image signal corresponding to the infrared light on the basis of the visible light intensity per unit time and the infrared light intensity per unit time.
