Broadband CCD imager

Abstract

The invention relates to imaging technology and provides a broadband CCD imager. The broadband CCD imager has a filter-disc switching control circuit (101), a CCD optically coupled circuit (102) and a CCD imaging processing circuit (103). A working method of a provided broadband imaging processing circuit (104) comprises the following steps of: receiving a button switch command or a 485 external control command from an imager; outputting a filter-disc switching control command to the filter-disc switching control circuit after an analysis is carried out; and receiving an analogue image which is output by the CCD processing circuit, starting corresponding working states, namely an original drawing state, a fog-transmitting state and a strengthened fog-transmitting state according to a control command instruction code and outputting a corresponding image mode. An input-output interface circuit (105) is provided and arranged at a rear panel in an imager main body. The broadband imaging processing circuit has an imager main body control mode and an external control mode. The broadband CCD imager breaks through the limits and overcomes the deflects of the realization of control mode of the conventional CCD fog-transmitting products in use.

Description

technical field [0001] The invention relates to imaging technology, and mainly proposes a wide-band CCD imager. Background technique [0002] With the development of digital imaging technology, the use of CCD imaging technology to achieve real-time monitoring of observation targets has been widely used in various fields of social life and industry applications. However, the quality of CCD imaging is greatly affected by the atmospheric environment, especially in environments with poor visibility such as smoke, fog, water vapor, and haze. [0003] The imaging quality of the CCD is greatly affected by the visibility of the environment. When the visibility is poor, the direct impact on the CCD is the decrease of image contrast and the increase of noise, which leads to a sharp decline in image quality, or even normal imaging at all. [0004] At present, the realization of CCD imaging technology has the following two ways. [0005] Color to black CCD camera working band is 0.4μm...

AI Technical Summary

Problems solved by technology

[0011] To sum up, the conditions for the use of the CCD fog penetration imaging system are limited to a certain extent, because the connection of the control cable must be provided between the central control module and the fog penetration processing module to complete the transmission of control commands, so the system can only It is used in some specific working environments. For example, the site must provide a control cable for control command transmission. If the connection of the control cable is not provided on site in some daily use environments, the CCD fog penetration imaging system cannot normally switch the working mode.
