Embodiment Construction

[0040] The implementation of the present invention will be described in detail below in conjunction with the drawings and examples, so that the realization process of how to use technical means to solve technical problems and achieve technical effects in the present invention can be fully understood and implemented accordingly.

[0041]In the following embodiments of the present invention, by configuring the unit color restoration module whose sampling center deviates from the geometric center to form a dithered sampling pixel array, when a part of the color is suppressed, it is compensated by suppressing another color, avoiding The color shift after image reconstruction overcomes the phenomenon of lack of sampling, and at the same time, the high-frequency details of the image signal are preserved because no low-pass filtering is required.

[0042] figure 1 It is a schematic diagram of a pixel array for dithering sampling in Embodiment 1 of the present invention. Such as fig...

Abstract

The invention discloses a dithering sampling pixel array, which belongs to the field of integrated circuits. The pixel array includes: a plurality of unit color restoration modules along the horizontal direction and vertical direction respectively; among the plurality of unit color restoration modules, each unit color restoration module includes two red sub-pixels, two blue sub-pixels, two a green sub-pixel, the sampling center of each unit color restoration module has an offset vector from the geometric center of the same unit color restoration module; the unit color restoration module in the plurality of unit color restoration modules is offset according to the sampling center The shift vectors are divided into several categories, and arranged according to the rule that the average sampling interval between the unit color restoration modules in two adjacent rows is constant, and the average sampling interval between the unit color restoration modules in two adjacent columns is constant. The invention avoids color shift after image reconstruction, thereby overcoming the lack of sampling phenomenon.

Description

technical field [0001] The invention belongs to the field of integrated circuits, and in particular relates to a dithering sampling pixel array. Background technique [0002] Image sensors are widely used in civil and commercial applications. Currently, the image sensor consists of a CMOS image sensor (CMOS IMAGE SENSOR, hereinafter referred to as CIS) and a charge-coupled image sensor (Charge-coupled Device, hereinafter referred to as CCD). For CCDs, on the one hand, in professional scientific research and industrial fields, CCDs with high signal-to-noise ratio are the first choice; on the other hand, in the field of high-end photography, CCDs that can provide high image quality are also popular. For CIS, it is widely used in network cameras and mobile phone camera modules. Compared with CIS, CCD has higher power consumption and greater difficulty in integration, while the latter has low power consumption, easy integration and higher resolution. Although it is said that ...
