Abstract

The invention provides a control method and system of removal filter, suitable for photoelectric imaging field, comprising setting work mode of removal filter; performing the command of turning on, off the removal filter or automatically switching the work state of the removal filter, based on the work mode of the filter. The invention can save the design cost of part of the periphery circuit and prevents the error action of removal filter resulted from the random fluctuation of illumination condition in short time, at the same time the work mode parameter of filter is set as automation mode, and the switching condition can be preset by user and when and how to switching the removal filter is flexibly realized, to satisfy the real requirement of the user.

Description

technical field [0001] The invention belongs to the field of photoelectric imaging, and in particular relates to a control method and system for moving an optical filter. Background technique [0002] The alias of the filter is Optical Low Pass Filter (OLPF), and its main function is to correct the incoming light of the Charge Coupled Device (CCD) and filter out the infrared light entering the color CCD. As far as the latter function of OLPF is concerned, CCD does not need to filter infrared rays under any circumstances. For example, when the lighting conditions are relatively poor, in order to obtain a clearer image, it is necessary to make the CCD feel as much light as possible to be able to perceive Infrared light, in this case, can no longer use filters; another opposite situation is when the lighting conditions are better, CCD can produce better images without infrared rays, in this case, if The CCD senses the infrared light, which will cause the color shift of the ima...
