【CIS output】
CIS output (Vp) is defined below;
・ Light intensity
・ Sensor IC Sensitivity
・ Storing time (illuminated time to Sensor IC )
Vp ＝ k × I × S ×T
【Remark】
1) To keep a quality of the image, Vp is an important factor
so that Light intensity (I) and Storing time (T) have to be
adjusted appropriately.
2) If the intensity of the light source becomes too strong,
CIS output becomes saturated. In order to avoid such
saturation of the output, adjust the illumination's intensity
(LED-duty) appropriately.
