Multi-linear-array image sensor and image processing method

Abstract

The invention discloses a multi-linear-array image sensor and an image processing method. The multi-linear-array image sensor comprises a control unit, a group of column parallel ADCs, N pixel arrays and M output circuits, the group of column parallel ADCs comprises M ADCs, and the M ADCs are connected with the M output circuits in a one-to-one correspondence manner; the control unit is suitable for generating D groups of electrode signals of a first time sequence and respectively inputting the D groups of electrode signals to the corresponding pixel arrays and the output circuit, so that a first image output under the control of the D groups of electrode signals has preset sub-pixel displacement relative to a reference image; wherein the output circuit for inputting the electrode signal and the first time sequence are determined according to the preset sub-pixel displacement and the physical spacing between the pixel arrays. According to the scheme, the multi-linear-array image sensor is utilized, so that a plurality of images which are about the same scene and have the preset sub-pixel displacement can be obtained more flexibly.

Description

technical field [0001] The invention relates to the field of sensors, in particular to a multi-line array 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 way 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] Wherein, in an area array image sensor, pixels are arranged in a two-dimensional area array. For each exposure, a complete frame of image can be obtained. In the linear 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 the 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.
