<p>A multispectral photoreceptive device and a sampling method thereof are provided. The method comprises: a first merging process, for pairwise merging and sampling among closely adjacent pixels in the same row and the different columns, the different rows and the same column or the different rows and different columns in a pixel array and obtaining the sampling data of a first merged pixel; a second merging process, for merging and sampling the sampling data of the first merged pixel obtained in the first merging process and obtaining the sampling data of a second merged pixel; and a third merging process, for obtaining the sampling data of a third merged pixel in a digital space by color changing and image zooming methods. The device and the method are applicable for the multi-pixel sharing reading and amplifying circuit of a single-layer colored photoreceptive chip, a single-surface double-layer multispectral photoreceptive chip and a double-surface double-layer multispectral photoreceptive chip. On the basis of an existing pixel reading circuit, the device and the method simply and directly realize the YUV format output of sub sampled images on the photoreceptive device while realizing high-performance sub sampling.</p> |
