    摘要： Provided is an endoscope device capable of performing appropriate NR processing in both of a white illumination light imaging system and a narrow band imaging system and a noise reduction processing method. An endoscope device 1 is provided with a noise reducing unit which selects a pixel of interest based on used filter information determined according to light emitted by a light source unit 3 and a characteristic of each filter forming a color filter 202a and detects motion between images captured at different times by using an electric signal output by the pixel of interest, thereby reducing a noise component included in the image signal.

    摘要： An imaging system color image acquisition including: an image sensor; a tunable spectral filter arranged in an optical path of light propagation towards the image sensor; and a controller connected to the image sensor and to the tunable spectral filter. The controller is configured and operable for generating a colored image by sequentially operating the tunable spectral filter for sequentially filtering light passing towards the image sensor with three or more different spectral filtering curves during three or more corresponding integration time durations. The tunable spectral filter is configured, as an etalon and includes a pair of reflective surfaces. At least one of the reflective surfaces includes a layer of high refractive index of at least n=2.3 or even higher than 3, or a layer of low refractive index, smaller than n=1. The configuration of the etalon provide wide transmission peaks of the spectral curves with full-width-half maximum (FWHM) in the range of about 50 to 80 nm, free spectral range (FSR) of at least 300 nm, and thickness of the etalon in the order to 1 mm or even less.

    摘要： Techniques are disclosed for providing compressed three-dimensional (3D) graphics rendering exploiting psychovisual properties of the human eye. In some embodiments, the techniques can be used to render one red-green-blue (RGB) channel per pixel location. In some example such cases, green pixels are rendered at one-half resolution, whereas red and blue pixels are rendered at one-quarter resolution. In some other embodiments, multiple RGB channels can be rendered at a given pixel location. In some example such cases, green pixels are rendered at full (e.g., actual) resolution, whereas red and blue pixels are rendered at one-quarter resolution. Missing RGB channel components can be interpolated using statistical and/or frequency domain properties of color spectra, in accordance with some embodiments. The techniques can be used, for example, to improve the power efficiency and/or rendered graphics quality of a graphics processing unit (GPU) or other rendering engine, in accordance with some embodiments.

    摘要： There are provided an apparatus and a method which generate an RGB image having less color noise and fewer false colors by inputting an RGBW image. The apparatus has an image sensor having an RGBW array, and an image processing unit which performs image processing by inputting a sensor image formed of an RGBW pixel signal output from the image sensor. The image sensor has a periodic array of a unit composition formed of each RGBW pixel, and has an array in which composition ratios of each RGB pixel within the unit composition are adapted to be the same as each other. The image processing unit converts a pixel array of the sensor image formed of the RGBW pixel signal, and performs at least either array conversion processing for generating an RGB array image or signal processing for generating each RGB image signal in which all RGB pixel values are set for each pixel position of the sensor image.
