The higher the pixel the more clearly the picture

The higher the pixels can really take a clearer photo? Want to know this problem, we first need to figure out what is a pixel? Intuitive said, if you will enlarge the photos taken, you will see photos taken by digital camera is a small particles made of a single color, these particles is the smallest unit of the whole image pixels.

Take a look at our camera, the so-called 12 million pixels, what was to come to 14 million pixels? Actually very easy to understand, such as your photos size is 4000 x 3000 pixels, and then use the two side multiplication, this value is about 12000000, also means that the camera has 1 2 million pixels.

Pixel arrangement is roughly like this

If the higher effective pixels, take pictures out of the clear? This is not necessarily, in the light ideally, camera imaging "resolution" and effective pixels, sensor size, image processor, and resolving power are directly related to camera lens, so can't simply jumping to conclusions. However, if the sensor area, processors of the same circumstances, with a "sharp" enough lens, then of course the higher pixel, according to the movie "clear". But if you take small DC and competing SLR, then due to the sensor and the lens has essential difference, so nature is no comparability.

Browse + print, how much pixel is enough?

Through the above analysis, we know that the size of the pixel is not the only reason, decided to photo clarity of DC and DSLR/single camera more is not comparable. Next we answer for you a lot of people are concerned about the problem, in everyday applications, browse photos + print sharply, how pixels is enough for us?

First look at you pictures of the most commonly used to browsing - playback in the computer! After investigation, now the mainstream of the display resolution is commonly: desktop below 1920 by 1080 pixels or, 14 inch laptop 1366 x 768 pixels, so calculate down, even 1080 full hd resolution, up to also however 2 million pixel level. This means that your monitor, can show a maximum of 2 million pixels of image information. So if not amplification, basically all cameras on the market, and even mobile phones are "good enough"!

Small print photos, usually 200-3 million pixels enough

If you like to print photographs to store, then according to the general digital photo shop just by the standards of the 120-250 dpi printing paper, we can draw the following conclusions.

Photo print and pixel table

Refer to the above table, even if is the big photo printing 20 inches, just also need 8 million pixels. Unless prior to print, you big cuts to a photograph, or excessive hedge pixel camera photo is not too obvious. Indeed, for a basic rinse only 8 inches family users, the picture below is more "meaningless" high pixel. So, if you don't rush the big picture, in fact, more than 10 million pixels will be suffice.
