Single pixel color image sensor system and color image acquiring method thereof

Abstract

The invention discloses a single pixel color image sensor system which includes a pixel array which is composed of a plurality of sub-pixel units, a read-out circuit and a Y address which are separately and electrically connected to the pixel array, an A / D converter which is electrically connected to an output end of the read-out circuit, an image balancing processor which is electrically connected to an output end of the A / D converter, an image output controller which is electrically connected to the output end of the image balancing processor and a LED radiating controller which is intended for radiating a to-be-acquired target. The sub-pixel units correspond to pixel points one by one and a filter is not provided. The LED radiating controller includes a red LED controller, a blue LED controller and a green LED controller. The read-out circuit is also electrically connected to an X address. According to the invention, the system herein has novel design, simple theory, is easy to produce, has high application value and wide promotion prospect.

Description

technical field [0001] The invention relates to a color sensor, in particular to a single-pixel color image sensor system and a color image acquisition method thereof. Background technique [0002] Currently, existing color image sensor circuits such as figure 1 As shown, among them, the pixel unit is used as the photoelectric conversion unit. In order to realize the acquisition of color images, each pixel unit contains four sub-pixel units, and red, green, blue, and green filters are placed on the four sub-pixel units, as shown in figure 2 , image 3 with Figure 4 As shown, in this way, the spectrum of the three color components of red, green and blue can be collected to obtain the most original color image data. If each pixel contains only one sub-pixel unit, without adding red, green, blue, and green filters, the sampled image is a black and white image. Although the image collected by this color image sensor in the prior art is clear, the manufacturing process of t...
