Problems solved by technology

Traditional cameras only have a dynamic range of 3:1, and they only sample the entire image once in the process of capturing an image, which inevitably leads to overexposure of bright areas in the entire image, or underexposure of darker areas

Embodiment Construction

[0015] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0016] Such as figure 1 As shown, a novel SDI wide dynamic face capture camera includes a casing 2 and a lens 1, the lens 1 is connected with the casing 2 through a lens interface arranged on the front panel 5 of the casing, and the rear panel of the casing is provided with SDI interface.

[0017] The casing top 4 on the casing 2 is also provided with two fixing holes 3, and the two fixing holes 3 are used for fixing the camera on other objects.

[0018] The said SDI interface is a BNC connector, which can realize coaxial cable power supply.

[0019] The SDI interface mentioned above is a 3G-SDI interface, which uses the SDI interface to transmit video signals, without compressing and packaging the video signals for transmission over the ...

Abstract

The invention discloses a novel SDI wide dynamic range (WDR) human face capturing camera which includes a housing (2) and a lens (1), wherein the lens (1) is connected with the housing (2) through a lens interface arranged on a housing front panel (5); a control module, a WDR processing module, a wireless communication module, an SDI transmitting module, a CCD sensor and a color filter are arranged in the housing (2); the control module is respectively connected with the WDR processing module, the wireless communication module and the SDI transmitting module; the WDR processing module is also connected with the CCD sensor; the CCD senor is connected with the lens through the color filter; an SDI interface is arranged on a housing rear panel; the SDI interface is connected with the SDI transmitting module. The novel SDI WDR human face capturing camera provided by the invention adopts the SDI interface to transmit video signals, and can obtain clear images in a sharp contrast environment.

Description

technical field [0001] The invention relates to a camera, in particular to a novel SDI wide dynamic face capture camera. Background technique [0002] The SDI interface is a "digital component serial interface", and the HD-SDI interface is a broadcast-level high-definition digital input and output port, where HD means high-definition signal. Since the SDI interface cannot directly transmit compressed digital signals, the compressed signals recorded by digital video recorders, hard disks and other equipment must be decompressed and output through the SDI interface before they can enter the SDI system. Repeated decompression and compression will inevitably cause image quality degradation and delay increase. For this reason, various digital video recorders and non-linear editing systems in different formats have stipulated their own interfaces for direct transmission of compressed digital signals. 3G-SDI is the third generation of SDI. With the advent of high-definition (HD) v...
