Webcam: Key Features

Webcam. digital photo, video camera Fixing the image in real time. A webcam, as a rule, is used to transmit video over the Internet, through special clients (programs), for example. Skype.

Main features of the webcam

You can evaluate the quality of a webcam by its parameters: matrix type, resolution, focusing, viewing angle, frame rate, optical zoom, connection interface and cable length.

Matrix type

Perhaps one of the most important parameters for choosing a webcam. The quality of the image when transferring photos, video data depends entirely on the type of matrix, since the bandwidth of the Internet channel does not always decide everything. As a rule, manufacturers equip webcams with CCD and CMOS matrices. The most widespread, in the segment of private webcams, is the CMOS matrix, since it is a cheaper analogue of the CCD matrix. Webcams equipped with CCD-matrices have: high image quality, improved color reproduction and low noise. Video cameras with CCD-matrixes are mainly used in video surveillance systems. Lee, you shouldn’t be negative about the CMOS matrix, since they have almost caught up with the image quality of the CCD matrix.

Resolution

The parameter indicates what maximum photo and video resolution the webcam has. In the matter of choosing this external device, this is just the case when you should not chase high performance. A perfectly acceptable resolution for video conferencing is 640×480, and for photo mode. 1280×1024.

Focusing

The second most important parameter of the webcam. There are two types of focusing: automatic and manual.

  • Automatic focusing. The principle of autofocus operation is as follows: if the subject accidentally leaves the field of focus, the system automatically adjusts the optics so that the picture becomes sharp again. The autofocus webcam transmits the best quality image. Autofocus is usually absent in inexpensive webcam models.
  • Manual focus. The word “manual” speaks for itself, the focus has to be adjusted manually by rotating the lens ring.

Viewing angle

The angle of view indicates how much area will be captured in the frame and depends on the physical size of the sensor and the optics of the webcam lens. The higher the viewing angle, the more freedom of movement in front of the webcam during the Videoconference.

Frame frequency

A parameter that determines the quality of video broadcasting, the range of which is 9.90 Hz. A webcam with a low frame rate is capable of transmitting, at best, a blurry image, at worst, transforming communication into a voiced slideshow. Too high a frame rate can lead to no picture at all if the Internet channel is not fast enough to support video broadcasts at that frequency. The most rational choice, in this situation, would be a webcam with an average frame rate of about 40.70 Hz.

Optical zoom

The presence of a zoom allows you to zoom in or out of the subject, which is very useful, since the webcam can be installed too close or far away in the process of organizing a workplace or leisure place. The optical zoom ratio indicates how many times you can change the scale of the survey.

Connection interface

Typically, a USB interface is used to connect a webcam to a PC. There are also: Wi-Fi cameras and IP web cameras. are connected to network equipment, since, having on board a built-in network card. The higher the USB version, the faster the data transfer rate. Therefore, if you have a good speed of the Internet channel, you can arrange high-definition video conferencing at a high frequency, which will provide the best picture quality.

Length of cable

A factor that affects the usability of the webcam, which gives the freedom to choose the location of the camera. The length of the cable may be limited by the version of the PC connection interface. So for USB version 2.0, the length varies from 0.5 to 2 meters.

When communicating with friends or colleagues through video conferencing, everyone wants to look attractive in the eyes of the other person. With the right approach, this can be easily achieved, even if you have the cheapest webcam at your disposal. Let’s find out what can cause problems for the image and how to improve the quality of the WEB-camera.

Main problems and ways to solve them

Color problem

  • The light that the computer monitor emits, despite NOT its low intensity, can distort the picture that is broadcast in the chat. Your face will be painted the same color as prevailing on the monitor.

Decision

  • To improve the situation, you need to interrupt the lighting from the monitor, turn on the desk lamp and place it on the side of the computer. So the webcam will display colors more correctly.

The problem is in the light

  • The light from the lamp was so strong that the face became almost white.

Decision

  • You can improve the image with a little Scattering of lighting. If your lamp has comments on the power regulator, a tracing paper letter will come to the rescue. Tape it to the lampshade and the light will soften. Things will be much easier if you are sitting in front of a webcam next to a light wall. You just need to turn the lamp away from your face and point it at the wall. in the light that will be reflected from it, there will be enough strength to cope with the monitor effect, and the picture quality will become clearer and more balanced.

Glasses problem

  • If you wear glasses, the monitor will reflect into the lens during video conferences.

Decision

  • To avoid this, in the monitor settings, you need to reduce its brightness. As a rule, if you decrease the brightness by 25-30%, the reflection in the glasses disappears. It will take 2-3 minutes to get used to a slightly darkened image.

The problem is white

  • Despite all the efforts, your face, for some reason, is painted in the wrong color. This could happen due to the peculiarities of the webcam itself. It’s all about the “white balance”. to correctly display the color gamut, any digital camera needs to know what white looks like. And if it is not there, then the brightest spot is taken as a standard of whiteness in automatic mode, and not depend on what color it is. Because of this, the display quality of other colors suffers.

Decision

  • If there is no real white in the webcam’s field of view, you can correct the situation by wearing a white T-shirt or shirt. So the standard of snow-white will appear in the cameras, and all colors, including the color of your face, will return to normal.

As you can see, it is not at all necessary to be a technical genius in order to improve the quality of a webcam and feel comfortable during a video conference. Have a nice chat.
