FIELD: physics, computer engineering.
SUBSTANCE: invention relates to multispectral reading photosensitive devices for reading sub-sampled data of photosensitive pixels in large-scale array photosensitive chips. The multispectral photosensitive device and pixel sampling method include: a first merging process for merging and sampling two adjacent pixels in the same row and the different columns, or in different rows and the same column or different rows and different columns in a pixel array to obtain 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 to obtain sampling data of a second merged pixel; and a third merging process; sampling data of a third merged pixel are obtained in a digital space by colour changing and image zooming methods.
EFFECT: enabling sub-sampling with high output and efficient image processing.
