Speaking I is one of my friends to buy Sony Ericsson t618 camera cell phone contact. That was my first exposure to a camera cell phone, do not laugh at me Oh. Hey. With the rapid development of science and technology, just a few years. Camera cell phones, such as have sprung up, is not nothing new things. I think that camera cell phones and no much use until I buy the Nokia 7610. The megapixels publicity and fascinated him, in fact, tell the truth and did not really understand what millions of pixels, until one day I found the photos to enlarge or less clear on the computer.

Camera cell phones are 100 000 pixels, was developed to 300,000, and then as 7610 up to 1 million, now there are 2 million, 5 million. Cell phone pixel calculated in accordance with what it? Resolution he and the largest cell phone can shoot photos? What is VGA, QVGA lens? What is digital zoom? What is optical zoom? And so on, please continue to read. cell phone jammer  has the various sales channels and selling modes.
Pixel maximum resolution. A camera pixel of the cell phone is the cell phone can shoot the biggest photo that can be rendered on the pixels. Such as we usually 30 megapixel camera cell phone supports an image capture up to 640 * 480 resolution photos, the product of the maximum resolution of 640 * 480 307 200 pixels, that is the biggest shot 640 * 480 resolution camera display 307,200 pixels, which is 300 000 pixels how to. Generally, a 1.3 megapixel camera support to shoot a maximum resolution of 1280 * 960 photographs, 2 million pixel camera can shoot 1600 x 1200 resolution photos. cell phone jammer  uses the DC-DC converter input voltage.
The principle is the case. As for the other pixels, we can in accordance with the analogy to this reason. VGA, QVGA lens. Cell phone profile, we often see such a sentence, the machine uses a VGA camera. Our 7710 introduction is written like this: built-in support 2x digital zoom 1.3-megapixel VGA camera. . . . . .

So simple that the VGA camera, 300,000 pixel camera. But with the rapid development of science and technology, the cell phone camera pixels continuously improve and has now grown to one million, two million or more. Then relative to the VGA camera, QVGA but also what is it? QVGA full written English is QuarterVGA, fourth Quarter, the Chinese meaning of the word, he means is a quarter of the VGA size.
