Embodiment 1

[0046] Such as figure 1 As shown, the embodiment of the present invention provides a super starlight camera, comprising: a lens 1 and a body; the lens 1 is fixed on the body, and the aperture value of the lens 1 is F0.68 to F0.78; for example, the aperture value is Lens 1 of F0.68, the focal length of lens 1 is 5mm, and the light diameter of lens 1 is 7.35mm. After experiments, the use of a large aperture lens with an aperture value of F0.68 to F0.78 can not only meet the shooting environment at night, but also ensure the imaging effect of the image. Compared with the existing lenses with aperture values ​​of F1 and F1.6, and shooting in a uniform low-light environment, the brightness value of the picture captured by F0.68 lens 1 is 5.43; the brightness value of the picture captured by the F1 lens is 2.52 ; The brightness value of the picture captured by the F1 lens is 1. And setting the ultra-large aperture lens 1 from F0.68 to F0.78 can greatly increase the light transmiss...

Embodiment 2

[0058] Such as figure 2 As shown, the embodiment of the present invention provides a super starlight camera control method, which is applied to the super starlight camera provided in the above embodiment, and the method includes:

[0059] S1: Receive target brightness value, brightness tolerance and brightness change rate threshold.

[0060] S2: Acquire the first brightness value at the first moment.

[0061] It is judged according to the target brightness value whether the first brightness value exceeds the brightness tolerance value.

[0062] If yes, execute step S3.

[0063] S3: Obtain the second brightness value at the second moment.

[0064] It is judged according to the target brightness value whether the second brightness value exceeds the brightness tolerance value.

[0065] If yes, execute step S4.

[0066] S4: Calculate the brightness change rate from the first moment to the second moment according to the first brightness value and the second brightness value. ...

Embodiment 3

[0086] An embodiment of the present invention provides a computer-readable storage medium. The computer-readable storage medium stores machine-executable instructions. When the computer-executable instructions are invoked and executed by a processor, the computer-executable instructions prompt the processor to run. Embodiment 2 provides Methods.

[0087] It should be noted that like numerals and letters denote similar items in the following figures, therefore, once an item is defined in one figure, it does not require further definition and explanation in subsequent figures.

Abstract

The invention provides a super starlight camera and a control method thereof, belongs to the technical field of monitoring equipment, and solves the technical problem of poor monitoring image effect in a dark environment in the prior art. The super starlight camera comprises a lens and a camera body, the lens is fixed on the machine body, and the aperture value of the lens is F0.68 to F0.78; an image sensor and a video codec are arranged on the machine body; the image sensor is a 1 / 1.8 inch image sensor; the lens is used for collecting images, the images passing through the lens are collected on the image sensor, the image sensor is used for converting image optical signals into image electric signals and sending the image electric signals to the video codec, and the video codec is used for decoding the image electric signals to form images.

Description

technical field [0001] The invention relates to the technical field of monitoring equipment, in particular to a super starlight camera and a control method thereof. Background technique [0002] With the development of electronic technology in the monitoring field, all kinds of monitoring products are developing in the direction of high sensitivity. At night, in low-light environments, existing monitoring equipment has dark images, large color noise, and details and colors of monitoring scenes. Unclear problems affect the effect of night monitoring. [0003] Therefore, the prior art has the problem of poor monitoring image effect in dark environments. Contents of the invention [0004] The purpose of the present invention is to provide a super starlight camera and its control method, so as to alleviate the technical problem of poor monitoring image effect in the dark environment in the prior art. [0005] In the first aspect, a super starlight camera provided by the pres...
