PRELIMINARY

1.3 Digital Responsivity

The specified digital responsivity is obtained if the gain is set to 98. In addition, the output depends

on the register setting for the digital shift. The values given are typical values which can vary

between different cameras:

For digital shift = 0: 400 DN/lx s @ 550 nm

For digital shift = 1: 800 DN/lx s @ 550 nm

For digital shift = 2: 1600 DN/lx s @ 550 nm

For digital shift = 3: 3200 DN/lx s @ 550 nm

LSB = least significant bit

See section 3.6.1 for the formula.

Example:

If the gain is set to 98, if digital shift is set to 0, and the quantity of light of 1 lux-sec has hit the

sensor, a gray value of 400 is output.

The quantum efficiency of the sensor is shown in Figure 1-1.
