With the popularity of the network, as a computer peripheral products camera quickly into millions of households. This major business opportunities but also to bring the camera industry flourishing. In the low barriers to entry, public mode rampant in the industry, camera product design, user applications, new features, technical specifications and other aspects did all articles on camera High pixel hype heat gradually calm when the camera manufacturers have started again "High frame" comparisons. From 15 frames / sec to 30 frames / second, to the current market to occupy the leading position of 60 frames / sec, camera Frame rate described as "Zhimakaihua - steadily high." Recently, more camera brand on the market hit a 120 frames / second, or even 150 frames / sec banner.

 Really as bad as some businesses publicity the case? Is not what we really need such a "fast" camera? Or this is a similar high-pixel camera hype? To this end, Xiao Bian specifically identified a number from the market of such products, a series of contrast, some of the following tests to uncover the camera for everyone "High frame" behind the secret and video effects for the users to seek the best choice.

What is the number of frames?

The so-called frame, that is, in a second transmission time, the number of images, the image processor can be understood as the number of times per second to refresh the image, usually fps ( Frames Per Second ) expressed. Each frame is a still image, the display frame in rapid succession will form a motion picture transmission. Image updates faster, the displayed image will be more smooth.

 We were able to use cameras to see a continuous image, because the image sensor constantly ingest and transfer to the screen onto the screen, when the transmission rate (ie the number of frames) reaches a certain level, the human eye can not distinguish between the screen time slot, so we can see the continuous dynamic picture.

 60 frames / sec video best choice

 Currently consumers are used to take pictures with the camera and video chat, and mainstream products currently on the market can achieve physical 130W pixels or more, for ordinary photos already well positioned to meet, (before the problem has been explored pixel); transmission in the picture , currently appearing on the market the camera images are mostly transmitted frame rate 15 frames / second, 30 frames /sec, 60 frames / sec and a handful of 120 frames / second camera products.

 Generally 30fps is acceptable, so the screen is not smooth to avoid the minimum frame rate of 30FPS . In addition to 30fps , some video formats such as AVI , second only provide 15 frames per second to transmit15 images. But for those who like to record video clips of my friends, at this stage, the bandwidth conditions, motion video reaches 60 frames / sec (320 * 240) screen, only the best video effects, video transmission also to achieve smooth, no blur blurred . Therefore, consumers in the purchase of camera products, the best choice 60 frames / second camera.

The actual effect of contrast

 Screens for different products transfer speeds, such as 30 frames / second, 60 frames / sec, 120 frames /sec products, small series from static camera, motion video and performance made ​​the following comparison between the three in order to better highlight differences and the pros and cons.
