SENSE-UP
AUTO
If SENSE-UP is set to AUTO, the maximum sense-up rate can be
limited to 2X-30FPS, 4X15FPS, 8X-18FPS, 16X-4FPS, 32X-2FPS or
64X-2FPS in SENSE-UP SETUP.
The integration frames vary automatically within the max. rate
according to the light level when light becomes low and DSS is
operating. The higher sense-up rate, the higher sensitivity but the
slower refresh rate. Some white dots may appear by sense-up due to
the image sensor’s long accumulation by a long shutter period.
