CCD image sensor and a CMOS image sensor comparison:88Dservice manual download site

Ease of integration with CMOS image sensor with A / D circuit, a digital signal processor (DSP) circuit. Only a single CCD image sensor to the latched state thousands of light on the sample point , CMOS can perform many other functions , such as A / D conversion, the load signal processing, white balance processing , and camera control ( white balance is adjusted by adjusting the image adjustment , so in a variety of lighting conditions and color photographs of the human eye to see the same scene color ) . In addition , CMOS image sensors as well as the advantages of low power consumption , the power consumption is about CCD image sensor 1 /10. But the CMOS image sensor in the resolving power and not as color CCD image sensor, image noise, the ability to accurately capture the dynamic image is not strong .88Dservice manual download site

Focus:88Dservice manual download site

Focus is a clear prerequisite for imaging , digital cameras generally have auto-focus feature. Digital camera auto-focus function is similar to traditional film cameras , there are active and passive forms.88Dservice manual download site

Active initiative that emits infrared camera ( or ultrasound ) , to focus the reflected goals. Passive is the camera does not emit any radiation and the imaging target focus.88Dservice manual download site
