Abstract: A method and processing device for image demosaicing is provided. The processing device comprises memory and a processor. The processor is configured to, for a pixel of a Bayer image which filters an acquired image using three color components, determine directional color difference weightings in a horizontal direction and a vertical direction, determine a color difference between the first color component and the second color component and a color difference between the second color component and the third color component based on the directional color difference weightings, interpolate a color value of the pixel from the one color component and the color differences and provide a color image for display.

Abstract: Devices, methods, and systems for detecting false color in an image. An edge preserving filter is applied to an image sensor output to generate a first demosaiced image. A low pass filter is applied to the image sensor output to generate a second demosaiced image. A hue difference between the first demosaiced image and the second demosaiced image is calculated. A false color region is detected responsive to the hue difference exceeding a threshold hue difference.

Abstract: A method and apparatus of performing processing in an image capturing device includes receiving an image by the image capturing device. The image is filtered to generate a first visible light component and a second infrared component. A decontamination is performed on the infrared component to generate a decontaminated infrared component, and an interpolation is performed on the visible component to generate an interpolated visible component, both of which are provided to an image signal processor (ISP) for further processing.
