Experts answer: The digital camera is the number of pixels? This problem in the digital camera can store one often heard. Obviously in the minds of many people to judge the most important factor is the camera good or bad pixels, maybe some people have objections, but anyway, pixel digital camera is indeed a measure of the important factors in grade One! Therefore become consumers and businesses frequently mention the vocabulary. That in the end what is the pixel resolution of what is it? , Bear with me to! 1. What is a pixel? In short, we often say the pixel is the CCD * CMOS on the number of optical sensing element, a photosensitive element After photographic, photoelectric signal conversion, A * D conversion step after the photos in output formed a Dian, if we Ba Fang Da image several times will find these colors Qi Shi Lian Xu is composed of many colors close of small square dots Suozu Cheng These constitute a small side point is the smallest unit of image "pixel" (Pix el). CCD pixels are divided into pixels and effective pixels, digital cameras on the market today marked the most part, not effective pixel CCD pixels. 2. What is the resolution? Said pixel resolution will have to talk about the. Because the two are inseparable! So-called "resolution" refers to unit length China, the expressed or the number of pixels captured. And the same pixel resolution is also divided into different categories. The most common is the image resolution, we usually say that the output of digital camera photos maximum resolution refers to the image resolution, the unit is ppi (PixelperInch) 3. Image pixel and sub- Identified the relationship between the rate of the definition of that pixel and resolution, let us look at the relationship between the two. Careful you might have found, pixels and resolution is directly proportional to the larger pixels, the higher the resolution. Let me illustrate! Because pixel and sub-pixel CCD pixels are usually effective for 2 million as Elements of digital cameras, the maximum image resolution is 1600 1200 = 192 million pixels, that is, the actual is 1.92 million effective pixels. Commonly referred to as 3 million pixel digital camera, the maximum video resolution is 2048 1536 = 3145728 pixels, ie Effective pixels 3.14 million. Other pixel digital camera, its effective pixel resolution and the conversion is also the same. Can be seen that the higher the pixels, maximum output of the higher image resolution. So when buying a digital camera, pixel is indeed an important consideration, the number of pixels specific needs, you can root According to their own needs.
