How Does A Digital Camera
By Jakob ... digital camera is not ... a magic box that came out of nowhere and has done wonders The digital camera is very similar to ... It also contains most of the associated components that the conventional camera contains, like lens and a shutter to let in light, however, instead of reaching a photosensitive film, the light is falling on network image sensors or photosensitive cells. Many of these differences are, but most stay in oblivion for the ordinary people. And the digital camera is its true respect, it is necessary to explore these areas and reveal the truth to light.
Looking a little more detail on working with the fantastic device, the digital camera. Building on the above lines, it can be deepened, the sensor network is basically a chip about 10 mm in diameter. Each image sensor is a charge coupled device (CCD) to convert light into electrical charges, and is essentially a silicon chip used to measure light. These charges are stored as analog data, which is then converted to digital via a device called an analog to digital converter (ADC). While the chip is a collection of tiny diodes sensitive sites named photo or pixels that convert light (or more scientifically, photons) into electrical charges called electrons. Pixels are very sensitive to light, so bright light that strikes them, the more the accumulation of electrical charges. Each receiver creates a table 1000 pixels and each pixel corresponds to stored information.
Take a look at each other, one can observe that quite a few digital cameras use CMOS chips (ie, Complementary Metal Oxide Semiconductor, a manufacturing technology of these chips) that based image sensors. The main advantage is that CMOS sensors are appreciably cheaper and simpler to manufacture than CCD sensors. Another great advantage of CMOS sensors is that they take much less power compared to other technologies in addition to the fact that the intensive use of them and can support the implementation of circuits Further on the same chip as ADC, some control units, etc. It can be noted that CMOS technology based cameras are small, light, cheap and also energy efficient, but at the expense of a certain amount of image quality.
However, the trend is that all cameras in the range of mega pixels and above use CCD chips instead of CMOS. This is because due to the image quality alone, leaving aside the differences.This price is essentially the fact of how digital cameras work Having known this difference, the experience would not take pictures of users, but still feel a kind of satisfaction in understanding the depths of a device that is as close to the eyes
The light comes from the digital camera through the lens, which is the same mechanism as the analog camera. And this light hits the CCD when the photographer presses the shutter button. The shutter opens and thereby illuminates every pixel, however, a different intensities.
