Problems solved by technology

[0003] In order to smoothly switch between two different glass sheets in the existing imaging device, it is necessary to set up an active filter switching module, and design enough space for the two sheets of glass to switch freely. The volume is large. In addition, since the filter switching module slides and switches through the cooperation of the chute and the guide post, the structure will age after long-term use, affecting the sliding effect, slowing down the response, or inaccurate sliding positioning. It will make the position between the two different pieces of glass that the lens is aimed at, which cannot play the role of normal filter switching, which affects the normal shooting location.
In addition, the existing imaging device only installs a manual filter switching module on the imaging module. The filter switching module needs to be manually activated to switch the filter elements after artificially judging the light conditions, and requires additional imaging. The battery power configured in the device operates

Embodiment 1

[0022] Example 1: Please refer to the attached figure 1 , the imaging device 10 shown therein includes an imaging module, a filter switching module 12 and a light sensing control module 13, the filter switching module 12 is located on the imaging module, between the filter switching module 12 The lens 14 of the imaging device 10 on the top, the filter switching module 12 includes a base 121 and a filter element 122, the base 121 includes a bottom plate 1211 and a side plate 1212 formed on the bottom plate 1211, the bottom plate 1211 has a receiving cavity 1211 ', the side plate 1212 is surrounded by a light hole 1212', the light hole 1212' communicates with the receiving cavity 1211', the filter element 122 is arranged in the receiving cavity 1211' of the bottom plate 1211, the filter The element 122 includes an electrochromic glass 1221 and an external circuit 1222. The electrochromic glass 1221 is located on one side of the light hole 1212'. The external circuit 1222 is elec...

Embodiment 2

[0028] Embodiment 2: The technical solution of this embodiment is substantially the same as that of Embodiment 1, the difference is that the imaging device includes an imaging module 21 and a filter switching module 22, and the filter switching module 22 is located in the imaging module On the group 21, above the filter switching module is the lens 24 of the imaging device 20, the filter switching module includes a base 221 and a filter element 222, and the filter element includes an electrochromic glass 2221 and an external circuit 2222, the external circuit 2222 is electrically connected to the electrochromic glass 2221. It is a control switch that controls the electrical connection circuit between the external line 2222 and the electrochromic glass 2221. By turning on / off the control switch, the different states of the electrochromic glass 2221 are activated. At this time, the filter The unit is powered by the battery provided.

Abstract

The invention discloses an imaging device and a filtering switching module of the imaging device. The imaging device comprises an imaging module, the filtering switching module and a light sensing control module, a base comprises a bottom plate and a side plate formed on the bottom plate, the bottom plate is provided with a containing cavity, a light passing hole is formed by the side plate in a defined mode and communicated with the containing cavity, a filtering element is arranged in the containing cavity of the bottom plate and comprises electrochromic glass and an external circuit, and the light sensing control module for controlling filtering switching is arranged in the filtering switching module. The invention further provides the filtering switching module. According to the imaging device and the filtering switching module of the imaging device, the intensity of light can be automatically detected, the electrochromic glass is controlled to be switched through the circuit, and therefore manual control of an operator is omitted.

Description

technical field [0001] The invention relates to the field of imaging equipment, in particular to an imaging device capable of shooting under conditions of different light intensities. Background technique [0002] In the existing photographing equipment, in order to meet the requirement of photographing in a dark environment, a filter switcher is arranged in the photographing equipment. The filter switcher can make the shooting device switch between a daytime shooting mode and a nighttime shooting mode. The filter switch generally includes a visible light glass plate for daytime shooting mode and an infrared light glass plate for nighttime shooting mode. The filter switcher is generally placed between the camera lens and the image sensor of the shooting device. When the light is sufficient, the filter switcher sets the visible light filter between the lens and the image sensor. Between the light paths, the shooting device can take normal color images at this time; when the...
