Array of color light filters More often the array of color light filters uses technology Bayer Pattern at which red, green and dark blue filters are allocated in chessboard order and the number of green filters is more than red or blue. It is connected to that the human eye is more sensitive to light with wavelength in a green range, than to dark blue or red ranges. Accordingly, doubling of number of green pixels should provide the best perception of brightness and more natural colors for a human eye (that very much reminds a ratio of brightness of the full video signal where brightness (Y) = 0,59G + 0,30R + 0,11B). Also as a result of usage of this technology sharper images turn out. The problem of correspondence of…

Differences Between The Digital And The Film Camera Part 4

Photoshop
Sensor control Till now almost all cameras in the market were estimated by quantity of pixels which the digital camera can shot (than it is more than them, the photo will be especially detailed). The quantity of pixels depends on the physical size and concentration of elements on a sensor control. The sensor control is heart of the digital camera, and as a sensor control acts with the help of different chip. The sensor control consists of set of photosensitive elements (photosites), containing photo diodes. Elements on the chip are ordered and form a matrix. Thus, matrix elements can be compared with pixels (no less than to name). Elements react to light and create the electric charge which size is proportional to quantity of got light. It is possible to…
