Experts answer:. What is a pixel? In short, we often say the pixel is the CCD * CMOS optical sensors on the number of components, a photo sensor through the photographic, photoelectric signal conversion, A * D conversion step after the output of the photo on the formation of a point If we put the image Great times, will find these continuous color tone is made up of many small square dots of similar composition, these small parties that constitute the image point of the smallest unit of "Pixel" (Pixel). CCD pixels are divided into pixels and effective pixels, digital cameras on the market today marked the most part, not the pixels CCD Effective 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 units of length, expressed or retrieve the number of pixels. And the same pixel resolution is also divided into different categories. The most common is the image resolution, we pass Often said that the biggest digital camera photos Output resolution refers to the image resolution, the unit is ppi (PixelperInch) print resolution is a very common name suggests, is the printer or printing equipment, output resolution, the unit is dpi ( dotperinc h) display resolution is the size of the Windows Desktop. Common settings are 640x480, 800x600, 1024x768 ... and so on. Screen font resolution: PC font resolution is 96dpi, Mac font resolution of 72dpi. Of course, there will be Other output device resolution. As the variety, in which no details, interested friends can go online to search on their own. 3. The relationship between image resolution and pixel resolution finished the pixel and the definition, let us look at the relationship between the two. Careful friend may have been found, pixels and sub- Classification rate is directly proportional to the larger pixels, the higher the resolution. Let us illustrate! As mentioned earlier, sub-pixel CCD pixels effective pixels and is 2 million pixels is usually a digital camera, the maximum video resolution is 1600 1200 = 192 million pixels, that is, the actual effective Pixel is 1.92 million. Commonly referred to as 3 million pixel digital camera, the maximum video resolution is 2048 1536 = 3145728 pixels, ie 3.14 million effective pixels. Other pixel digital camera, its effective pixel resolution and a conversion as well. Can be seen , The higher the pixels, maximum output of the higher image resolution. 4. The relationship between print resolution and pixel print resolution, related to the size of our photo prints, and therefore more important. In fact, calculation is very simple: 200 megapixel digital camera, 1.92 million effective pixels, maximum output 1600 1200 photo width: 1600Pixels * 300dpi = 5.3 "high: 1200Pixels * 300dpi = 4" means that if printing with 300dpi output resolution, up to 5.3 4-inch print photos, usually photos Size: 5 inches: 5 3.56 inch: 6 4 is clear to see, 200 million pixels able to effect 300dpi maximum 5-inch photo print. (Note: The human eye can tell the maximum resolution of 300dpi, beyond this resolution, the human eye can not see the difference, that is, Say 300dpi and 600dpi in the human sight is no difference, so now the largest printing equipment, the design of output resolution is 300dpi, of course, everyone asked for the definition is not the same, in general, can make to achieve 200dpi Most people are satisfied with 2 000 000-pixel prints 6-inch photos, in most people it seems very clear. ) Summary: As mentioned above, the "Print Size" and the image resolution is closely related, as long as the image resolution to change the print size will be followed by changes in the pixel and image resolution, a direct relationship there, so the three can With each conversion. The most fundamental of which is pixels. So when buying a digital camera, pixel, or an important consideration, the number of pixels specific needs, according to their needs.
