*4: f(CLK)=5 MHz
*5: An increased current consumption at the video output terminal rises the sensor chip temperature causing an increased dark current.
Connect a buffer amplifier for impedance conversion to the video output terminal so that the current flow is minimized.
Use a JFET or CMOS input, high-impedance input op amp as the buffer amplifier.

*9: Photoresponse nonuniformity (PRNU) is the output nonuniformity that occurs when the entire photosensitive area is uniformly
illuminated by light which is 50% of the saturation exposure level. PRNU is measured using 510 pixels excluding the pixels at both
ends, and is defined as follows:
PRNU= ΔX/X × 100 (%)
X: average output of all pixels, ΔX: difference between X and maximum or minimum output
*10: Measured with a tungsten lamp of 2856 K
