Description

Technical Field

[0001] This utility model relates to the field of camera technology, and in particular to a camera color accuracy reproduction device based on a color temperature sensor. Background Technology

[0002] In the field of camera technology, in order to achieve accurate color reproduction of captured images, cameras equipped with color temperature sensors are usually used for shooting. The core principle of this type of device is to use the color temperature sensor to detect the color temperature of the environment in real time, and then dynamically adjust the color parameters of the camera based on the detected color temperature data, so that the images captured by the camera can more realistically reflect the colors of the objects themselves. Currently, most color temperature sensors in such devices on the market are installed below the camera. This installation method creates a certain parallax between the color temperature sensor and the camera. Due to the parallax, the ambient color temperature data read by the color temperature sensor cannot accurately reflect the light source conditions at the location of the subject being photographed by the camera. Consequently, when the camera adjusts its color based on this inaccurate data, it produces incorrect color reproduction results, affecting the camera's shooting quality and thus having limitations.

[0003] The reason for this problem is that parallax causes the field of view of the color temperature sensor and the camera to not be completely consistent. When the camera is pointing at the subject, the color temperature sensor detects the light source in the area below the subject, rather than the light source in front of the subject. In actual shooting scenarios, the light sources in different areas are different. The camera adjusts the color based on the data below, which cannot accurately reproduce the true color of the subject, resulting in color deviation in the captured image. Utility Model Content

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] This utility model provides, for example Figure 1 The illustrated device for accurate color reproduction of a camera based on a color temperature sensor includes a camera 1. The camera 1 contains a color reproduction unit 2, which includes a light guide tube 21, a color temperature sensor 22, and a PCB board 23. PCB board 23 is fixedly mounted inside camera 1. Color temperature sensor 22 is fixedly mounted on PCB board 23. PCB board 23 is electrically connected to color temperature sensor 22. Light guide tube 21 is L-shaped. The turning point of light guide tube 21 is cut and polished into a 45-degree bevel, and a reflective film is coated on the bevel. One end of light guide tube 21 is connected to color temperature sensor 22, and the other end of light guide tube 21 is connected to camera 1.

[0017] Example 1: In this example, when the device is in use, the lens group 25 of the camera 1 is aimed at the subject being photographed. Ambient light enters through the lens group 25, while some light enters the light guide tube 21 through the micro light guide hole on the protective cover plate 24. Since the light guide tube 21 is L-shaped and the 45-degree inclined surface at the bend is coated with a reflective film, the light is reflected inside the light guide tube 21 and accurately transmitted to the color temperature sensor 22. The color temperature sensor 22 transmits the detected color temperature data to the PCB board 23. The PCB board 23 transmits the data to the image processor 27. The image processor 27 processes the image data captured by the lens group 25 in combination with the color temperature data and adjusts the color parameters of the camera 1, thereby achieving accurate color reproduction of the captured image.

[0018] like Figures 2 to 3 The illustrated device for accurate color reproduction of a camera based on a color temperature sensor includes a camera 1. The camera 1 contains a color reproduction unit 2, which includes a light guide tube 21, a color temperature sensor 22, and a PCB board 23. PCB board 23 is fixedly mounted inside camera 1. Color temperature sensor 22 is fixedly mounted on PCB board 23. PCB board 23 is electrically connected to color temperature sensor 22. Light guide tube 21 is L-shaped. The turning point of light guide tube 21 is cut and polished into a 45-degree bevel, and a reflective film is coated on the bevel. One end of light guide tube 21 is connected to color temperature sensor 22, and the other end of light guide tube 21 is connected to camera 1.

[0019] A protective cover 24 is fixedly mounted on one side of the camera 1. The protective cover 24 has a trapezoidal structure and a micro light guide hole inside. The light guide tube 21 is connected to the micro light guide hole. A lens assembly 25 is provided on one side of the protective cover 24 and is fixedly mounted to the protective cover 24.

A power cord is connected to the bottom of the camera 1 and is electrically connected to the PCB board 23.

[0020] Example 2: In this example, when installing the protective cover 24, it is necessary to ensure precise alignment between the micro light guide hole and the light guide tube 21 to avoid light leakage. The protective cover 24 is made of high-strength plastic, which ensures both protection and reduces the overall weight of the device. A flexible connecting strip 26 is fixedly mounted on one side of the lens assembly 25, and the lens assembly 25 is electrically connected to the PCB board 23 through the flexible connecting strip 26. The flexible connecting strip 26 is made of ribbon cable with good bending resistance. During the connection process, it is ensured that the ribbon cable is in close contact with the interface of the lens assembly 25 and the PCB board 23 to avoid poor contact. The image processor 27 uses a high-performance dedicated image processing chip. During assembly, it needs to be fixed to the PCB board 23 by soldering, and the solder joints must be firm to prevent cold solder joints, so as to ensure the normal operation of the image processor 27. A light shield 28 is sleeved on the outer surface of the light guide tube 21, and the light shield 28 is fixedly mounted to the color temperature sensor 22. The light-shielding tube 28 is made of a black plastic tube to enhance the light-shielding effect. When connecting the tubes, it is necessary to ensure that the light-shielding tube 28 completely covers the outer surface of the light guide tube 21 and is tightly fixed to the color temperature sensor 22 to prevent the light-shielding tube 28 from becoming loose and affecting the light-shielding effect. The bottom of the camera 1 is connected to a power cord, which is electrically connected to the PCB board 23. The power cord is made of copper core wire with good insulation properties. When connecting, the connector of the power cord must be firmly connected to the power interface on the PCB board 23 and insulation treatment should be done to prevent short circuits.
