Figure 2: Difference between interleaved and non-interleaved mode
Following table gives the exposure time at which the read-out mode is switched for the full
resolution of 640x480 pixels. See Section 4.5.3 for the calculation of the frame rate.

4.2 Pixel Response
4.2.1 Linear Response
Normally, the camera offers a linear response between input light signal and output gray
level. In addition, a linear analog or digital gain may be applied.
4.2.2 Analog Gain
The MV-D640 camera series offer an analog on-chip gain between x1 and x18 in steps of 1.
For the color model, the four color channels red, green1, blue, green2 can be adjusted
independently.
Important! Using a high analog gain will degrade the image quality. Although it is
possible to configure analog gain up to x18, we strongly recommend using a
lower gain than gain x8.
