(5) Frame rate (readout speed)
The sensor of this camera realizes both low noise (6.6 electrons) and high speed
readout (64.9 fps with all pixels) simultaneously, owing to 1 line parallel simultaneous
readout using column A/D.
(6) Real-time correction functions
There are a few pixels in the CMOS image sensor of this camera that have slightly
higher readout noise performance compared with surrounding pixels. When using the
camera, there is a chance that the data from variant pixels caused by uneven
illumination and optics is not negligible in the image. Therefore, the camera has variant
pixel correction feature to further improve image quality. The correction is performed in
real-time without scarifying the readout speed at all.
(7) USB 3.0 bus Interface
Image signals undergo A/D conversion inside the camera, and are transmitted
externally via the USB 3.0 bus interface as 12 bit digital data. The camera can also be
controlled via this bus.
(8) Camera operation modes
The camera has three operation modes: 1) Free running mode, in which the exposure
and readout timing are controlled by the internal microprocessor, 2) External trigger
mode, in which the exposure and readout timing are decided by External trigger and 3)
Software trigger mode, in which the exposure and readout timing are decided by
application software.
