Imaging control circuit of multipurpose space camera and multipurpose space camera

Abstract

The present invention provides an imaging control circuit of a multipurpose space camera and a multipurpose space camera, which include at least two control modules, each control module is used to independently control the corresponding CCD image sensor and CMOS image sensor; the control module includes a control unit and a digital transmission interface unit, the control unit includes a CCD image processing unit and a CMOS image processing unit, and the CCD image processing unit and the CMOS image processing unit respectively process and integrate the digital image data transmitted by the CCD image sensor and the CMOS image sensor to Generate parallel data; the data transmission interface unit converts parallel data into LVDS signal transmission. The beneficial effect of the present invention is that: each piece of CCD has a set of independent processing circuits, which can respectively set the camera parameters for each piece of detectors, and can minimize the inter-chip crosstalk and improve the imaging signal-to-noise ratio. Multiple independent control circuits improve reliability and reduce the problem of overload caused by sharing processing circuits.

Description

technical field [0001] The invention relates to the technical field of electronic applications, in particular to an imaging control circuit of a multi-occasion and multi-purpose space camera for space detection, and also relates to a multi-purpose space camera with the imaging control circuit. Background technique [0002] China currently refers to space exploration activities on celestial bodies beyond the earth as deep space exploration. With the improvement of the level and capability of human spaceflight technology, the concept of deep space exploration will gradually develop. In other words, the technological development in the field of deep space exploration and the connotation of the concept of deep space exploration are mutually reinforcing. [0003] Deep space exploration refers to the exploration of breaking away from the gravitational field of the earth and entering the space of the solar system and space. Then, naturally, the devices performing deep space explora...

Problems solved by technology

However, according to the requirements, TDI CCDs are often required to work at a higher line frequency, which leads to a certain high-frequency coupling between the spliced ​​TDI CCDs, and this coupling will be manifested in the final image. thereby affecting the quality of the image

The multiple TDI CCDs of traditional space cameras share a set of processing circuits, which makes it difficult to avoid coupling noise between adjacent CCDs. At the same time, due to the sharing of a set of processing circuits, the power consumption of multiple spliced ​​CCDs will also be concentrated in one set. processing circuitry, so thermally noisy
