Problems solved by technology

However, when the infrared camera is in a strong backlight situation, the pictures it collects are black. Therefore, when it is used as a monitor, it is often impossible to take a clear image because the light it is in is too strong, making it difficult for the monitors. After various illegal events (such as theft, robbery, etc.), useful information can be obtained through the images taken by it, thus losing its monitoring function. Therefore, how to make the infrared camera device adapt to different light and shoot clear images has become a basic Technical issues that technical personnel in the field need to solve urgently

Embodiment 1

[0017] The infrared imaging device capable of adapting to light of the present invention mainly includes: an infrared imaging device body, a light-shielding object, a photosensitive device, and a control unit.

[0018] The infrared camera body is used to shoot objects with infrared light to obtain corresponding images, for example, it can be an infrared camera with a supplementary light.

[0019] The shading object is installed on the surface of the image sensor of the infrared camera body, and is used to block the image sensor so that it cannot sense light. Please refer to Figure 1a and Figure 1b , in this embodiment, the shading object 11 can be an opaque square sheet, and when it does not block the image sensor 13, it is in a contracted state (such as Figure 1a shown), Figure 1b A schematic diagram of the image sensor 13 is partially covered. In addition, the image sensor can be a CCD device or a CMOS device, and the light-shielding object is not limited to this embodi...

Embodiment 2

[0023] Another infrared imaging device that can adapt to light of the present invention mainly includes: an infrared imaging device body, a light-shielding object, an analysis unit, and a control unit. unit to obtain the infrared light intensity in the scene of the infrared camera device, that is, the analysis unit is mainly used to analyze the infrared light intensity when shooting according to the pre-shot image of the infrared camera device body, when the pre-shot image is black , the analysis unit can determine that the intensity of infrared light in the scene where the infrared camera body is located is too strong, and accordingly it sends an instruction to the control unit to control the movement of the shading object to block part of the light from entering the infrared camera. The image sensor of the device body.

[0024] The photographing method that makes infrared imaging device adapt to light of the present invention mainly comprises the following steps:

Abstract

The invention relates to a method for enabling an infrared photography device to adapt to light, which comprises the following steps: firstly, presetting a shading object whose shading quantity can be adjusted on the surface of an image sensor of the infrared photography device, when the light intensity of the infrared photography device in a shooting scene, which is obtained from the measure of a photoreceptor or analyzing a pre-shot image by an analyzing unit, exceeds the preset value, confirming the ratio of the occupied area of a to-be shot object in the to-be formed image according to the focal distance of the infrared photography device, the clear and visual distance range of a corresponding lens, the optimum distance for imaging of the to-be shot object, then adjusting the shielding object according to the ratio and enabling the object to cover the corresponding part of the image sensor, which enables the uncovered part of the image sensor to induct infrared light reflected by the to-be shot object, thereby forming a corresponding clear image, preventing the defect of unclear images due to too strong light, reducing the monitoring risks exist in an existing infrared photography device for monitoring.

Description

technical field [0001] The invention relates to a shooting method and a corresponding device for making an infrared camera device adapt to light. Background technique [0002] The infrared camera device can use the infrared imaging principle to capture images in the dark environment, so it is widely used in various monitoring systems. However, when the infrared camera is in a strong backlight situation, the pictures it collects are black. Therefore, when it is used as a monitor, it is often impossible to take a clear image because the light it is in is too strong, making it difficult for the monitors. After various illegal events (such as theft, robbery, etc.), useful information can be obtained through the images taken by it, thus losing its monitoring function. Therefore, how to make the infrared camera device adapt to different light and shoot clear images has become a basic Technical issues to be solved urgently by those skilled in the art.
