Camera, the higher the pixels the better?
The higher the pixels the better?
This is a lot of people will ask in buying a digital camera, "you see is not the 6-megapixel 3-megapixel camera than the much better?", "Is not the 8-megapixel digital camera a good way?" And so on. For the purchase of error should be noted that according to need to buy is the right way. In pursuit of the principle for the purchase of high-pixel, not necessarily to buy a good digital camera.
Some digital cameras advertised a product that up to 600 million pixels of resolution, while the price is relatively low, the temptation for the average consumer is undoubtedly very great. The camera's manual carefully, not difficult to find so-called six-megapixel resolution, but is obtained through hardware interpolation, but the actual 3.3 million total pixels, but without a valid output pixel interpolation hardware, but also three million or so. This digital camera Fuji digital camera and some made most apparent. Fuji Fortunately, after the photo was able to accept the interpolation. But made it, in order to meet some of the digital cameras do not understand the blind pursuit of high-pixel only know the taste of friends, but also engage in interpolation, the absence of core technology, the effect of interpolation can not accept.
Pixel interpolation can really distinguish the total pixels and effective pixels, the difference in today's market, consumers still are not many, of course, often with the profile in addition to those dealing with consumer digital cameras. This mainly refers to the digital camera has not been in-depth study of consumers wanted to buy some digital camera manufacturers took advantage of this weakness of consumers, advocates a big section on how how high-resolution camera, and then induced consumption for those who buy it.
Chosen based on a digital camera you buy the largest non-interpolated pixels:
From a consumer point of view of practical applications, most users are used to take pictures using a digital camera, then digital printing. Now commonly used 200 million to 500 million pixels a few have been able to meet daily needs. More than 2 million pixels is the most basic requirements of printing photos, 2 million up to 1600 × 1200 pixel resolution (which is the maximum resolution, recommend the use of 1280 × 960), according to the standard to calculate the general 300dpi, 2.1 million pixels output can be perfect 5-inch photos, but can reach about 500 million pixels of resolution 2580 × 1936, to perfect the output 14-inch photos. Speculation on the hot market of 800 million, according to this algorithm can output more than 16-inch photos. But fairness, you are using to do? Wash a 14-inch photo how much money! ? If you say the words displayed on the computer also shows 19-inch monitor to 2048 * 1536 it, so much the photos that you have to narrow it. Do not say you buy a 8-megapixel digital camera is to the 8-megapixel photos reduced to 3-megapixel point of view, if this 5-megapixel are enough.
