Embodiment Construction

[0036]Several embodiments of the invention will be described below in the context of binary pixel arrays. However, it will be noted that the invention is not limited to binary pixel arrays. In fact, the different example embodiments have broad application in any environment where an implementation maps input pixel values ​​to output pixel values ​​through a process that is not determined in part.

[0037] now refer to Figure 1a , the image transmission sense applied in example embodiments may be a binary image sensor arranged to provide a binary image IMG1. An image sensor may include a two-dimensional array of photodetectors such that the output of each photodetector has only two logic states. The logic states are referred to herein as the "black" state and the "white" state. The image sensor can be initialized so that all detectors are initially in a black state. By exposing them to light, individual detectors can be switched to a white state. Thus, the binary image IMG...

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 initially unknown. A setup making use of a statistical approach may be used to determine the color filter setup to produce correct output images. Subsequently, the color filter information 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] A binary image sensor may include, for example, more than 10 9 a single photodetector. Each individual photodetector has two possible states: an unexposed "black" state and an exposed "white" state. Therefore, a single detector does not reproduce different shades of gray. The local brightness of the image can eg be determined by the local spatial density of white pixels. The size of the individual photodetectors of the binary image sensor can be smaller than the smallest size of the focal spot that can be 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 size. The resulting image data can be so large that it becomes impractical to store and process the binary digital image in a digital camera or even in a desktop computer. [0003] Therefore, a solution is needed to improve the application of binary digital image sensors...
