The sensitivity of a CMOS sensor is usually 10 times lower than that of a CCD sensor. The human eye can see the Targets below 1 lux illumination (night of the full moon). The CCD sensor can usually see the Targets below 0.1 ~ The target with less than 3 lux illumination is 3 to 10 times the sensitivity of the CMOS sensor.The sensitivity of the CMOS sensor is generally within the range of 6 to 15 lux. The CMOS sensor has a fixed noise 10 times higher than that of the CCD sensor, fixed pattern noi

Industrial cameras are indeed expensive. Differences between industrial cameras and ordinary cameras (DSC: (1) Industrial cameras have very short shutter times and can capture fast moving objects. For example, if you stick your business card on the fan blade and rotate it at the maximum speed, capture an image with an

Motion (http://www.lavrsen.dk/foswiki/bin/view/Motion/) is a small, lightweight but powerful application that can be used to manipulate surveillance cameras on Linux. It works with any Linux-enabled camera, including all v4l webcams, many IP cameras, and the NCR (axis) camera, which also controls panning and tilting functions. Motion can record videos and snapshots in JPEG, PPM, and MPEG formats, and you ca

use the proposal to repair or replace, After all, many cameras are now free of drive, plug on it can be used, we can try to suit their own methods. 2. What to do with the built-in camera of the notebook computer? Now many people are accustomed to using laptops to chat online, many laptops also have built-in cameras, this built-in camera has a very small number of problems, the computer system has been in

In unity projects, we often encounter the ability to share pictures after a screenshot, in order to prevent the infringement of content and enhance the ability to spread, we need watermark function. In unity, this implementation: 1, need to have two orthogonal cameras 2, two cameras with different depth 3, depth smaller because the rendering time than large, so as the main map rendering 4, depth large r

source community also launched a Easycamera cloud camera, probably the working principle is that the camera will always be connected with the cloud monitoring platform of the public network, will be the camera every moment of audio and video data, alarm data, capture data, etc. are sent to the cloud, For storage, video, analysis, and playback, so much to break through the limitations of the network, whether the camera in the intranet, or exposure to the public network, as long as the camera can

Digital cameras, as an outstanding embodiment of digital technology, are becoming a new favorite of consumer electronic products with their superior quality of use. They have gradually begun to enter ordinary homes, however, it is expensive, so we should be cautious when choosing a digital camera.

In unity, this is implemented as follows: 1. Two Orthogonal cameras are required. 2. Two cameras use different depth3. depth is smaller because the rendering time is earlier than the previous one, so as the rendering of the main Image 4, dep

It is not hard to tell from the extensive publicity of canon that the story of Canon began in 1933, precisely because it was founded in November 1933 by the "Institute of precision optics ...... In that year, as the "camera country" of the world, Germany had two major brands-Leica/Leica and Conway's/contax. Both companies are producing 35mm focal plane shutter cameras that represent the highest technical level at that time. In the early 1930 s, Le
