Digital zooming for color filter array-based image sensors
In this paper, zooming methods which operate directly on color filter array (CFA) data are proposed, analyzed, and evaluated. Under the proposed framework enlarged spatial resolution images are generated directly from the CFA-based image sensors. The reduced computational complexity of the proposed schemes makes them ideal for real-time surveillance systems, industrial strength computer vision ...
متن کاملHigh Sensitivity Color CMOS Image Sensor with WRGB Color Filter Array and Color Separation Process Using Edge Detection
We have developed a CMOS image sensor with a novel color filter array (CFA) where one of the green pixels of the Bayer pattern was replaced with a white pixel. A transparent layer has been fabricated on the white pixel instead of a color filter to realize over 95% transmission for visible light with wavelengths of 400-700 nm. Pixel pitch of the device was 3.3 um and the number of pixels was 2 m...
متن کاملColor filter array with sparse color sampling crosses for mobile phone image sensors
In order to solve the conflict between the size constraints of mobile phone cameras and image quality, it is an effective approach to improve the light sensitivity of imaging sensors. A color filter array comprising sparsely distributed crosses of color sampling blocks is proposed, in which nearly 69% of elements are transparent ones that detect luminance directly with a higher sensitivity than...
متن کاملPlasmonic color filters for CMOS image sensor applications.
We report on the optical properties of plasmonic hole arrays as they apply to requirements for plasmonic color filters designed for state-of-the-art Si CMOS image sensors. The hole arrays are composed of hexagonally packed subwavelength sized holes on a 150 nm Al film designed to operate at the primary colors of red, green, and blue. Hole array plasmonic filters show peak transmission in the 40...
متن کاملColor filter array patterns for small-pixel image sensors with substantial cross talk.
Digital image sensor outputs usually must be transformed to suit the human visual system. This color correction amplifies noise, thus reducing the signal-to-noise ratio (SNR) of the image. In subdiffraction-limit (SDL) pixels, where optical and carrier cross talk can be substantial, this problem can become significant when conventional color filter arrays (CFAs) such as the Bayer patterns (RGB ...
