Monitor the difference between the camera 720p and 1200 lines
720P is 1280 X 720 pixels short, usually also known as 100W like. Is a parameter of the clarity of the digital camera system.
P and line, are the unit of image clarity, but P is used in the digital system, the Chinese full name for the pixel, and the line is used in the simulation system, the Chinese full name for the TV line.
1200 lines, if simply literally on the analog camera system that represents the clarity of the 1200 TV line, but the current market, the emergence of the 1200 line, strictly speaking, is a mountain plug products, is a digital camera using 1080 X 1960 CMOS lens to convert products into analog cameras.
If the above, a little knowledgeable people, will be divided into digital systems or analog systems to use these two units, but the market there are many comrades of the three classes, and no matter what the system equipment, to 忽悠 on the 忽悠, so 1200 lines are also widely used in analog systems and digital systems, which is a bit messy.
Simply from the literal point of view, 1200 lines look better than 720P, but the actual effect, the 1200 line of the camera is through digital-analog conversion, and the effect of CMOS lens application in the simulation system, matching the problem (popular say acclimatized) , So the image of the 1200 line is much worse than the 720P image.
