Abstract
The invention provides an optical filter device arranged between a camera lens and an image sensor. The optical filter device comprises the camera lens, the optical filter and an image sensor assembly; the optical filter device is characterized in that the camera lens is arranged on the image sensor assembly; and the optical filter is arranged between the camera lens and the sensor. The optical filter device is used for arranging the optical fiber between the camera lens and the image sensor, so that the problem that the product space design is limited as the conventional optical fiber is arranged in front of the camera lens is avoided.
Description
Technical field
The present invention relates to a kind of lens assembly, especially a kind of optical filter device that is installed between camera lens and the imageing sensor.
Background technology
At present, video technique maturation is applied to each side, and as safety monitoring, they be unable to do without camera.The quality of camera directly influences the quality of imaging, and special cam lens also will install optical filter additional and filter specific light.As filtering infrared ray, colored CCD or CMOS also can respond to infrared ray, but infrared ray can cause D.S.P can't calculate correct object color, therefore must install a tablet filter additional, and the light middle infrared (Mid-IR) is partly filtered out.
Common thermal camera or infrared camera by day or under the well-lighted situation, are to take chromatic image or photograph by available light; At night, be to take black-and-white image or photograph by the infrared lamp light filling, this just requires thermal camera or infrared camera to install additional can follow the filtering apparatus that automaticallyes switch according to light, by day or under the well-lighted environment, the optical filter unlatching work of can automaticallying switch of this device, to shoot more video display or the photograph of the colour of good quality, at night or insufficient light, when needing by the shooting of infrared lamp light filling, this device optical filter that can automatically switch is closed, and allows thermal camera or infrared camera can photograph infrared image or the photograph of black and white.
Yet optical filter is the plane, and common automatic switching control equipment is to place camera lens the place ahead, like this, when product design, need consider the space of this device institute temporary, can limit to product design, especially use wide-angle lens, the inconvenience that this point brings is more outstanding.
Summary of the invention
The present invention namely is the weak point that exists at optical filter in the prior art, and a kind of optical filter device that is installed between camera lens and the imageing sensor is provided.
For addressing the above problem, the technical solution used in the present invention is: a kind of optical filter device that is installed between camera lens and the imageing sensor, comprise camera lens, optical filter and image sensor module, it is characterized in that: described camera lens is installed on the described image sensor module, and described optical filter places between camera lens and the sensor.
Further, described optical filtering comprises automatic switching control equipment.
Further, described camera lens comprises at least one imaging len.
Further, described camera lens can be wide-angle lens.
Further, described image sensor module comprises printed circuit board (PCB) and the sensor chip that is installed on the described printed circuit board (PCB).
The beneficial effect that adopts technique scheme to produce is: optical filter is installed between camera lens and the imageing sensor, and having solved common optical filter is to place camera lens the place ahead to limit the problem of product space design.

Wherein, 1 is camera lens, and 2 is optical filter, and 3 is image sensor module.
Embodiment
Below in conjunction with accompanying drawing; a kind of optical filter device that is installed between camera lens and the imageing sensor of the present invention is described; purpose is better to understand technology contents of the present invention for the public; rather than to the restriction of described technology contents; in fact; in initiative spirit essence of the present invention, to the improvement of described apparatus structure, comprise the increase and decrease of corresponding components and parts and replace all within the present invention's technical scheme required for protection.
As shown in Figure 1, a kind of optical filter device that is installed between camera lens and the imageing sensor, comprise camera lens 1, optical filter 2 and image sensor module 3, it is characterized in that: described camera lens 1 is installed on the described image sensor module 3, and described optical filter 2 places between camera lens and the sensor.
Described camera lens comprises at least one imaging len.
Described camera lens can be wide-angle lens.
Described image sensor module comprises printed circuit board (PCB) and the sensor chip that is installed on the described printed circuit board (PCB).
Described a kind of optical filter device that is installed between camera lens and the imageing sensor, optical filter is installed between camera lens and the imageing sensor, and having solved common optical filter is to place camera lens the place ahead to limit the problem of product space design.
