In order to save time and cost, no matter which industry’s solution, once the main components are selected, they generally will not be changed at will. The same is true for the electronic colposcope industry. The selection of main components is very important. Is SONY HD camera module FCB-EV7520 equipped with 3G-SDI interface board an ideal solution for electronic colposcopy?
1. Camera movement
For the electronic colposcope solution, the camera movement is very important now, because if you want to change other movements after the solution is done, it will involve the change and replacement of interface board, wire, remote control, etc. For the choice of camera, Xuanzhan technology gives the following suggestions:
(1) Now the mainstream is high-definition camera, the definition is relatively high, for now it is enough, of course, you can also choose 4K ultra HD camera with higher definition and resolution, which is the direction of the future;
(2) When choosing the camera, we should pay attention to whether the selected movement will stop production soon? Need to pay attention to the official news;
(3) Automatic focus is a necessary function of the electronic colposcope camera, because if you have to focus every time, it is a waste of time;
(4) SONY FCB-EV7520 full HD camera is recommended by Xuanzhan Technology here. The movement is equipped with a 30 times optical zoom lens, with an effective pixel of about 2.13 million and a maximum output resolution of 1920*1080. Its wide dynamic and automatic focus function can quickly obtain high-definition pictures.

2. Interface board
(1) According to the more than ten years of experience of Xuanzhan Technology in high-definition video products, the electronic colposcope generally adopts SDI, HDMI and USB interface boards for high-definition camera movement, and users can choose them according to their actual needs;
(2) However, it should be noted that the wires of SDI and USB interface can be made into composite wires, and all of them can be hidden in the metal pipe of the fixed bracket. If you choose HDMI interface, you can not make a composite wire hidden in the pipe;
(3) If you choose 4K ultra HD camera movement, you must choose HDMI 4K interface board or the upcoming 12G-SDI interface board;
(4) FCB-EV7520 is a SONY full HD camera module, Xuanzhantechnology recommends the use of 3G-SDI interface board, 3G-SDI interface board is the use of coaxial cable will not compress the digital signal high-speed transmission, with real-time, no distortion, stable performance and other advantages.
For the electronic colposcopy solution with SONY FCB-EV7520 camera and 3G-SDI interface board, the cables include LVDS cable, RF cable, etc.
4. Remote control
(1) The remote control of the electronic colposcope can be developed into wired or wireless according to the needs of customers;
(2) The number of keys can also be defined as 8 keys, 10 keys or 12 keys, the number is not limited.
5. Collect cards
(1) The image acquisition card of the computer side of the electronic colposcopy can choose the built-in PCI/E interface or the external USB interface;
(2) The acquisition card is divided into three types: standard definition, high definition and 4K. FCB-EV7520 needs to choose SDI HD video acquisition card;
(3) For easy operation, foot switch can be selected. It is mainly used to control the camera to freeze and take pictures;
SDI HD video acquisition card
(1) The clarity of the display of the electronic colposcope is based on the highest resolution of the camera to select the display of the same resolution;
(2) As for the size, you can choose according to your own needs.
