Story: The specifications of the camera
1. Sensor (image sensor)
Matrix is a reception point light passes through the lens, it transforms the analog signal (analog) of real life, the values of (digital) to then be processed, stored, and recreates for us to see. The number of sensors on a sensor point is usually written in units of Mega-Pixel (million points of acquisition). For example, 5.1 MP, 7.2 MP. 12.4MP.
1a. CCD (charge-coupled device) sensors are very popular, previously considered as most Vietnamese advantages in manufacturing digital cameras, usually fitted in the factory tours, professional, semi-professional. Was invented in 1969 in the laboratory in 1969 AT & T Bell Labs by Willard Boyle and George E. Smith.
1b. CMOS (complementary metal oxide semiconductor) is a different type of sensor. Its first generation was inferior to CCD in many ways, so it is applied on the cheap camera. However, with the development of technology, the next generation CMOS has many technical advantages, so it has been applied to high-end cameras. (Most of the professional and semi-professional cameras of Canon are using CMOS)
CCD and CMOS basic differences on how to transmit signals.
Each cell receives the signal light CCD, and CCD few or many cells that transmit signals to a node, from which the new signal is digitized (digitalized).
In contrast, each cell itself CMOS switch from analog to digital signals, CMOS addition each cell is equipped with additional signal amplification section, part handling interference (noise) …
CCD or CMOS advantages over Vietnam? That is a question left open. Recently, however, many of Nikon camera has switched to using CMOS instead of CCD.
