In the senior digital camera, generally contain AE function and AF functionaAEservice manual download site

1) AE function when DSC camera at the subject , CCD image brightness according to the lens came the strength of the voltage signal into a digital CCD , DSP arithmetic then processed according to CCD digital voltage signal , and then transferred to the result of the operation MCU quickly find the right size optimal value of shutter speed and lens aperture , automatic exposure control AE institutions by the MCU .aAEservice manual download site

2) AF functionality directly using the digital voltage signal outputted from the CCD as the focus signal, after comparison before and after the MCU operation AF lens driving mechanism movement.aAEservice manual download site

Many digital cameras currently classified , if you press the image sensor can be divided into CCD and CMOS digital cameras digital cameras .aAEservice manual download site

CCD Digital Camera:aAEservice manual download site

CCD digital camera is the CCD image sensor using a digital camera to record images, document camera is high . CCD itself can not distinguish between the various colors of light , use a different color filters used in conjunction with , and therefore CCD digital camera has the following two ways:aAEservice manual download site

1 , a lens and a beam splitter optical image signal into R, G, B three colors , and three pieces were acting on the CCD, these three colors of light by the CCD is converted to electrical simulation , and the A / D converter is converted to a digital signal, and then the digital signal processor DSP is stored in the memory.aAEservice manual download site

2 , the position of each pixel with the three respective R, G, B three color filter CCD, the image signal through the optical lens is the role of the different sensors , respectively , and convert them simulation signals, and the A / D converter converts the digital signal, and then the digital signal processor DSP is stored in memory .aAEservice manual download site

CMOS Digital Camera:aAEservice manual download site

CMOS digital cameras is the use of CMOS image sensor digital camera to record images. The way it works is similar to a digital camera with a CCD , there is a low-grade camera.
