Camera with built-in polarizer switching mechanism

Abstract

The invention discloses a camera with a built-in polarizer switching mechanism, which comprises a polarizer switching mechanism and a camera body. The mechanism is located at the rear of the front cover and inside the camera body. A CCD image sensor is arranged behind the polarizer switching mechanism. The CCD image sensor is facing the light hole. The CCD image sensor is fixed on the CCD circuit board. The rear portion of the camera body is attached to the heat sink, and a main circuit board is also installed in the camera body, and the main circuit board is electrically connected to the CCD circuit board. The invention integrates the polarizer switching mechanism inside the camera, which is beneficial to reduce the volume of the switching mechanism and the camera. And the built-in design of the polarizer switching mechanism is that the overall structure is isolated from the outside world, so that the aging of plastic parts in the switching mechanism can be delayed, and the problem of dustproof of the polarizer is also solved.

Description

technical field [0001] The invention relates to a camera, in particular to a camera with a polarizer switching mechanism. Background technique [0002] When using a camera to shoot scenes, especially when shooting reflective objects, such as reflective metal surfaces, glass surfaces, etc., it is necessary to install a polarizer to obtain a clearer image. For some cameras, it is necessary to set a polarizer switching mechanism. When the camera needs to use a polarizer, the polarizer can be automatically added to the imaging optical path through the switching mechanism; The polarizer is removed, so the polarizer switching mechanism can realize the switching between the filter and the polarizer. [0003] The polarizers (or polarizer switching mechanisms) of existing cameras are all placed outside the lens, which leads to a complex overall structure of the camera, thereby reducing the reliability of the system and increasing the workload of system failure maintenance; and becau...

Problems solved by technology

[0003] The polarizers (or polarizer switching mechanisms) of existing cameras are all placed outside the lens, which leads to a complex overall structure of the camera, thereby reducing the reliability of the system and increasing the workload of system failure maintenance; and because the polarizer is arranged on the lens In addition, to match the size of the objective lens of the lens or even larger, the required polarizer area is larger, which also makes the switching mechanism more bulky and difficult to install
