Yesterday, according to the API provided by Flex, a USB camera was obtained. But when I plug in multiple cameras on the same computer, I can only get one of them. According to the flex API, the method for obtaining multiple cameras is as follows: VaR arrayofcams: array = camera. names; VaR askcam1: Camera = camera. getcamera (arrayofcams [0]); VaR askcam1: Camera = camera. getcamera (arrayofcams [1]);

Seeing this picture represents my VS2015 cross-platform Moblie development tool was installed successfully.After the installation was successful last week, I wanted to see the fun of cross-platform development, but I couldn't find the right entrance. This week again, adjusting supervised a little bit. The results found an entrance. So write a Hello world and share it with everyone. Let's take a look at the protagonist, that's Apache Cordova.Apache Cordova is a set of device APIs that allow mobil

Give the photographer a detailed explanation to share the effective pixel of the Canon 650D camera. Analytical sharing: Canon 650D has about 18 million effective pixel CMOS image sensors both high quality and low noise, the overall balance of outstanding, can be detailed performance scenery, but also smooth reproduction of the character skin level. The image can be printed on a large size, and some images will not be lost as a sense of interpretation. Compared with small digital

Digital camera is a relatively delicate machine, especially the lens and LCD screen. For friends who like to go out shooting, after going out, will inevitably be stained with dust. Every time we travel out of the shooting, we should first the digital camera lens, LCD screen and the fuselage to clean and maintain, lest the cumulative after the LCD screen and lens scratches.Dust is a big taboo of digital equipment, the use of digital video cameras must

Digital cameras are currently one of the fastest growing peripherals, and their configuration in Linux is very simple. The gphoto2 software package supports digital cameras. Generally, you only need to install and configure the gphoto2 package to use a digital camera in Linux. Gphoto2 of the latest version 2.1.6 supports more than 616 types of digital cameras fro

Low-and middle-end digital cameras generally have three flash modes: Automatic Flash, red eye elimination, and flashlight closure. A more advanced product also provides "Force flash" or even "Slow flash. So what are their differences? What are the points of attention during actual shooting? I also want to hear from you. For more information, see. 1. Automatic Flash In general, the flashlight mode is preset in the "auto flash" mode without any configu

USB cameras are cheap and easy to use, while opencv also contains API functions for reading USB camera video data. In Windows XP, this API function is implemented using the Windows VFW module. Below, I will give Reference code: # Include "stdafx. H"# Include "cv. H"# Include "highgui. H"# Include "iostream"Using namespace STD; Int main (INT argc, char * argv []){Cvcapture * Cap = cvcreatecameracapture (0); // initialize the pointer captured by the ca

In the previous article "Python: monitoring functions implemented by cameras", I suddenly thought that I could upload the images I collected to Weibo directly, and then I could use my mobile phone to view the desired location in real time, the implementation idea is as follows: A. program a collects and stores images every 30 s through the camera; B. Program B uploads the collected images to Sina Weibo every 30 s; The implementation is as follows: 1.

Ubuntu VirtualBox Virtual Machine to install XP settings, USB devices and cameras are enabled in LINUX, sometimes it is inevitable to use some windows programs, such as QQ or shopping, the best option for the moment is to install the XP Virtual Machine. The following are some specific configurations. First, install the Virtual Machine Software and install the XP Virtual System. These are very simple: 1: install the enhancement package of the virtual m

Currently, there are four types of consumer-Level Digital Cameras: 2/3 inch, 1/1. 8 inch, 1/2. 7 inch, and 1/3. 2 inch. The larger the size of CCD/CMOS, the larger the photosensitive area, the better the imaging effect. The effect of a 1/1-8 inch 3 million-pixel camera is usually better than that of a 1/2-7 inch 4 million-pixel camera (the latter's photosensitive area is only 55% of the former ).

In cocos2dx, the horizontal version of the game sorts out how cameras move When playing a horizontal version game, it is inevitable to use the camera to move, and generally in a 2D horizontal version game to simulate some 3D effects, the method of stratified movement is used (that is, the moving speed of each layer is different, to simulate the slow moving of objects in 3D. In cocos2d, parallaxNode is provided to achieve different levels of moving spe

How to implement real-time monitoring of haikang cameras in HTML? Recently, the company has arranged for CCFA to implement real-time monitoring of a webpage playback camera. Baidu has been on the Internet for a long time, and many of them are directly implemented using the vlc plug-in. However, currently mainstream browsers do not support the vlc plug-in, and it has not been successful for a long time. Most of the online implementations are as follows

I will give you a detailed analysis of the valid pixels of the Canon 500D camera.Analysis and sharing:Canon 500D valid pixels are 15.1 million pixels.All right, the above information is all the details of the effective pixel resolution shared by Canon 500D cameras for photography enthusiasts, I believe that you are very clear about the effective pixels of the camera. I hope that the effective pixel information provided above will help you.
