Embodiment 1

[0033] Such as Figure 1 to Figure 5 As shown, the broadcast-level high-speed high-definition camera of this embodiment includes a casing 1 and a lens bayonet 2. The inside of the casing 1 is provided with an image sensor 3, a circuit board 4 and a sensor panel 5, and the lens passes through the lens bayonet 2. The adapter ring 6 is fixed on the front of the casing 1 and is connected to the image sensor 3; the circuit board 4 is installed inside the casing 1 through a fixing screw column 7, including a storage device 8, an FPGA (Field-Programmable Gate Array, field programmable gate array) data acquisition board 9, main board 10 and image signal processor 11;

[0034] The storage device 8 adopts a solid state drive (Solid State Drives, SSD) with a PCI-E interface, and its capacity is more than 300GB. It is a standard PCI-E2.08X board card, and its external dimensions are 168.55*68.91*17.14mm , since there is a large amount of storage space, a large amount of video data collec...

Embodiment 2

[0056] The main feature of this embodiment is: the storage device 8, the FPGA data acquisition board 9 and the main board 10 can be set independently instead of being set in a box. All the other are with embodiment 1.

[0057] In addition, those skilled in the art should know that the above-mentioned storage device 8, FPGA data acquisition board 9, main board 10, image signal processor 11, etc. can also use other hardware of the same type.

[0058] To sum up, the broadcast-level high-speed high-definition camera of the present invention has a simple structure and is easy to operate and use. By using an FPGA chip with a PCI-E hard core, a stable PCI-E X8 system can be efficiently developed, thereby realizing broadcast-level high-definition video High-speed data acquisition, transmission, storage and playback.

Abstract

The invention discloses a broadcast-quality high-speed high-definition camera, comprising a machine case and a lens mount, wherein an image sensor and a circuit board are arranged in the machine case; a lens is fixed at the front part of the machine case via an adapter ring of the lens mount and is connected with the image sensor; the circuit board comprises a storage device, an FPGA data acquisition board, a main board and an image signal processor; the FPGA data acquisition board uses an FPGA chip with a PCI-E hard core and is connected with the image sensor and the image signal processor via SPI interfaces; the image sensor is connected with a staticizer on the FPGA data acquisition board via a low voltage difference signaling (LVDS) receiver; the main board is connected with the storage device and the FPGA data acquisition board via PCI-E interfaces. The broadcast-quality high-speed high-definition camera of the invention is simple in structure, convenient for operating and using, and can be used for collecting, transmitting, storing and playing broadcast-quality high-definition video data with high speed.

Description

technical field [0001] The invention relates to a broadcast-level camera, in particular to a broadcast-level high-speed high-definition camera, belonging to the field of camera technology. Background technique [0002] The basic working principle of the camera is to convert the optical image signal into an electrical signal for collection, editing, storage or transmission; when the user uses the camera to shoot an object, the external scene and the light reflected on the object are collected by the camera lens, Through the optical path system, it is focused on the light-receiving surface of the imaging device (such as the target surface of the imaging chip), and then the brightness and darkness of the light are converted into electrical signals of different sizes through the semiconductor imaging device, that is, the so-called "video signal". Since the photoelectric signal obtained by the photosensitive chip is very weak, the electrical signal must first be amplified by the ...
