Camera Matrix

Russian consumers are increasingly using digital cameras and cameras. Every day, world manufacturers produce new models that provide more and more opportunities for photos. Today, an ordinary person may find it difficult to decide the choice of camera. Sometimes experienced salespeople in the store and then are not able to give an intelligible advice on his choice. That is why an amateur photographed, and even more so a professional must know some features and characteristics of modern devices.

The camera matrix is one of the main elements in such devices. It is a sensory device with a high sensitivity, which is capable of ensuring the conversion of an optical image projected onto it by a lens into a digital signal. The matrix of the camera or camera has a direct influence on the detail and quality of the images taken. Let's take a closer look at this particular element.

The matrix of a digital camera includes a plurality of photosensitive elements that convert an optical image into an electrical image. Each pixel of the matrix forms one point of the final image. By design, they can be divided into full-frame, progressive scan, buffered columns, with frame buffering, back-light and interlaced scanning. In this matrix can be divided into two main types, which are now commonly found in the sold cameras.

Types of camera dies

For a long time, metal oxide complementary semiconductors (CMOS) were used as matrices, whose sensitivity to light was discovered in the sixties. Here, the signal can be read from anywhere, you only need to specify the line and column numbers. In this case, each pixel has a read signal amplifier. A little later appeared devices that had charge communication (CCD), which initially significantly exceeded the CMOS-matrix. In such systems, the signal was read in the same way as a CRT (cathode ray tube), that is, from left to right and from top to bottom. Silicon photodiodes acted in this case as photosensitive elements. In the early nineties a significant improvement in CMOS sensors was made. Because of such features of this type of matrix, such as the possibility of obtaining normal sensitivity and high image quality only with significant matrix sizes, they are usually used in professional cameras having large dimensions. If we talk about inexpensive amateur models, it is better to choose those that are equipped with a CCD matrix. Companies such as Canon and Nikon produce models of cameras with modified CMOS matrices, which are a kind of transitional option.

The camera matrix has such an important characteristic as resolution. Under the resolution is meant the number of sensing elements on the matrix, each of which perceives light and converts it into a certain electric charge. It is important to understand that there is no sense in chasing the number of pixels, because the quality of the printed images is practically the same, and the difference can be seen only under the magnifying glass.

Another significant characteristic that the camera's matrix possesses is its physical size. Most often, the more physical size it has, the better the signal-to-noise ratio, which will allow you to get an image of higher quality, having natural colors. We can say that the larger the matrix size with one number of pixels, the higher the quality of the photographs.
