Embodiment Construction

[0028] 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.

[0029] In the following embodiments of the present invention, the unit color restoration modules are arranged in three directions to increase the degree of freedom in image sampling, and realize the acquisition of details in more directions, so as to achieve high frequency without loss of image signals. In the case of details, there has been a lack of sampling phenomenon.

[0030] figure 1 It is a schematic plan view of a pixel array with three degrees of freedom according to an embodiment of the present invention. In order to illustrate the structure of the pixel array more clearly, structural parts such as lenses and filters are omitted, so detail...

Abstract

The invention discloses a pixel array with a novel structure, which belongs to the field of integrated circuits. A pixel array with a new structure has three degrees of freedom, including: a plurality of unit color restoration modules respectively arranged along the first direction, the second direction and the third direction; among the plurality of unit color restoration modules, each unit The color restoration module includes magenta sub-pixels, cyan sub-pixels, yellow sub-pixels and green sub-pixels, and the magenta sub-pixels, cyan sub-pixels and yellow sub-pixels are arranged around the green sub-pixels. By configuring the unit color restoration module in three directions to increase the degree of freedom in image sampling and to achieve the acquisition of details in more directions, so as to achieve the lack of sampling phenomenon without losing the high-frequency details of the image signal .

Description

technical field [0001] The invention belongs to the field of integrated circuits, and in particular relates to a pixel array with a new structure. 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 CCD may be sup...
