Determining color information using a binary sensor

Abstract

The invention relates to forming an image using binary pixels. Binary pixels are pixels that have only two states, a white state when the pixel is exposed and a black state when the pixel is not exposed. The binary pixels have color filters on top of them, and the setup of color filters may be known to some degree. A setup making use of a statistical approach may be used to determine the color of incoming light to produce output images. Consequently, the approach may be used with the binary pixel array to produce images from the input images that the binary pixel array records.

Description

Background technique [0001] Binary image sensors may include, for example, more than 10 9 a single optical detector. Each individual optical detector has two possible states: an unexposed "black" state and an exposed "white" state. Therefore, separate detectors do not reproduce different grayscale gradients. The local brightness of the image can be determined, for example, by the local spatial density of white pixels. The size of the individual optical detectors of the binary image sensor can be smaller than the smallest size of the focus spot provided by the imaging optics of the digital camera. [0002] However, storing or transmitting such binary digital images may be difficult or impossible due to the large data volume. The resulting image data may even be so large that it becomes impractical to store and process binary digital images on a digital camera or even on a desktop computer. [0003] So, for a practical solution, a solution that improves the applicability of...
