Summary of the invention
At the problems referred to above, the present invention propose a kind of easy and simple to handle, read the video camera automatic gaining effect checkout gear of image immediately.
For solving this technical problem, the present invention takes following scheme: a kind of video camera automatic gaining effect checkout gear, comprise casing, adaptation board, pictute plate, monitor, a plurality of controlled light sources and back of the body power supply, described casing is the hollow reservoir that two ends are provided with opening, described pictute plate is located on the opening of casing one side, adaptation board is located on the opening of casing opposite side, adaptation board is provided with loophole, camera lens to be measured is located on the adaptation board loophole, monitor is connected with camera lens to be measured and is used to obtain captured image, described each controlled light source is located at respectively between described pictute plate of box inside and the camera lens to be measured, and backlight is located near the opposite side of pictute plate away from camera lens to be measured.
Further improve and be: be provided with shading sleeve between described adaptation board and the camera lens to be measured.
Further improve and be: described backlight is a lamphouse light source.
By adopting the aforementioned techniques scheme, the invention has the beneficial effects as follows: form low-light (level) by changing each controlled light source, if need to form a high illumination, the contrast technique known, checkout gear of the present invention only need be opened backlight just can obtain a high illumination, the device that adopts is easy, and simple to operate.
When utilizing above-mentioned detection device to carry out the detection of video camera automatic gaining effect, may further comprise the steps:
(1), the camera lens with video camera to be measured is connected with the perforate of adaptation board; If there are certain printing opacity slit in the camera lens of video camera to be measured and the perforate of adaptation board, shading sleeve can be located between adaptation board and the camera lens to be measured;
(2), regulate and control each controlled light source and backlight so that change the illuminance on the pictute plate, the image that forms on the monitor on the contrast video camera output can detect the automatic gaining effect of video camera to be measured immediately.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention.
Embodiment
Now the present invention is further described with specific embodiment in conjunction with the accompanying drawings.
With reference to figure 1, present embodiment discloses a kind of video camera automatic gaining effect checkout gear, and it comprises casing 1, opening 11, opening 12, adaptation board 2, shading sleeve 3, camera lens 4, pictute plate 5, monitor 6, power supply 7, controlled source 81, controlled source 82 and lamp box power supply 83, wherein:
The madial wall employing black of casing 1 not reflectorized material is made, and makes embodiments of the invention in the detecting operation process, and the change of illuminance obtains the most real reflection; Described casing 1 is provided with the hollow reservoir of opening 11 and opening 12 for two ends, described pictute plate 5 is located on the left surface of opening 11 of casing 1, adaptation board 2 is located on the opening 12 of casing 1, and adaptation board 2 can fold, change, so that casing 1 adaptive different video camera, adaptation board 2 is provided with loophole, camera lens 4 is located on adaptation board 2 loopholes, described shading sleeve 3 is located between described adaptation board 2 and the camera lens 4, shading sleeve 3 adopts the opaque flexible material of black to make, be used to guarantee form in the casing 1 a lighttight confined space, guarantee the normal operation of checkout gear in testing process of the embodiment of the invention, obtain the most real testing result; Monitor 6 is connected with camera lens 4 and is used to obtain captured image, and power supply 7 electrically connects with camera lens 4 and is camera lens 4 power supplies.Described controlled source 81 and controlled source 82 are located at respectively between casing 1 inboard described pictute plate 5 and the camera lens 4, the intensity of illumination of described controlled source 81 is slightly larger than controlled source 82, controlled source 81 and controlled source 82 provide the illumination that forms low-light (level) source for the checkout gear of the embodiment of the invention, lamphouse light source 83 is located at the left surface of pictute plate 5, distance should not be far away excessively, and lamphouse light source 83 provides the illumination that forms high illumination source for the checkout gear of the embodiment of the invention.
When utilizing above-mentioned detection device to carry out the detection of video camera automatic gaining effect, the perforate of camera lens 4 with adaptation board 2 is connected, for the printing opacity slit that the perforate that prevents camera lens 4 and adaptation board 2 exists certain naked eyes to observe, shading sleeve 3 is located between adaptation board 2 and the camera lens 4.
When forming the illumination gradient, open controlled source 81, its light opening 12 by casing 1 that projects on the pictute plate 5 reflexes on the camera lens 4, obtains an illuminance 1; Same, to open controlled source 82 and obtain an illuminance 2, illuminance 2 intensities of illumination are a little more than illuminance 1.By that analogy, thereby obtain illuminance different and that strengthen successively: illuminance 1, illuminance 2, illuminance 3, illuminance 4, illuminance 5, illuminance 6, illuminance 7 obtain the gradient of an illuminance.Following table is in the testing process, an illumination gradient that draws by the embodiment of the invention:
| Illuminance | Controlled |
