Table 8-2 MER-G-P/MER-G series camera exposure time setting range
* The exposure precision of the camera is limited by the sensor, when the steps in the user’s interface and
the demo display as 1μs, actually the steps is one row period. When the value of the ExposureTime cannot
be divisible by the row period, round up to an integer should be taken, such as the row period is 36us,
setting 80us exposure time, and the actual exposure time is 108us.
When the external light source is sunlight or direct current (DC), the camera has no special requirements
for the exposure time. When the external light source is alternating current (AC), the exposure time must
synchronize with the external light source (under 50Hz light source, the exposure time must be a multiple
of 1/100s, under 60Hz light source, the exposure time must be a multiple of 1/120s), to ensure better image
quality. You can set the exposure time that is synchronized with the external light source by using the
demo or interface function.
