lines) data sampling at dark (light shielding).
1. One valid photocell in one reading is fixed as measurement point.
2. The output level is measured during the reset feed-through period which is averaged over 100 ns to get
3. The output level is measured during the video output time averaged over 100 ns to get “VO
4. The correlated double sampling output is defined by the following formula.
