Multi-line array image sensor and image processing method

Abstract

A multi-line array image sensor and an image processing method. The multi-line image sensor includes: a control unit, a group of column-parallel ADCs, N pixel arrays and M output circuits; the group of column-parallel ADCs includes M ADCs, the M ADCs and M output circuits One-to-one correspondence; the control unit is adapted to generate the D group electrode signals of the first timing sequence, and input the D group electrode signals to the corresponding pixel arrays and output circuits respectively, so that the D group electrode signals control the output The first image of , has a preset sub-pixel displacement relative to the reference image; wherein, the output circuit for inputting the electrode signal and the first timing are based on the preset sub-pixel displacement and the physical distance between the pixel arrays determined. With the above solution, using the multi-line image sensor, multiple images with preset sub-pixel displacements about the same scene can be obtained more flexibly.

Description

technical field [0001] The invention relates to the field of sensors, in particular to a multi-line image sensor and an image processing method. Background technique [0002] The imaging principle of the solid-state image sensor is: convert the incident light signal into a charge signal, then convert the charge signal into a voltage or current signal, and finally output the converted electrical signal. According to the form in which the pixels of the solid-state image sensor are arranged in the chip, the solid-state image sensor can be divided into an area array image sensor and a line array image sensor. [0003] Among them, in the area array image sensor, the pixels are arranged in the form of a two-dimensional area array. For each exposure, a complete image can be obtained. In a line array image sensor, the pixels are arranged in a linear array, and only one line of image information can be obtained for each exposure, and a complete two-dimensional image information can...

Problems solved by technology

[0005] When using a multi-line array image sensor to obtain multiple images of the same scene with preset sub-pixel displacements, it is achieved by only adjusting the physical spacing between pixel arrays in the multi-line array image sensor, which is less flexible.
