3.1. Selecting the Frame Rate
With the system, you can record images from 60 to 3,500 fps (or 2,000 fps at 15Ktype) using the full
1,280x1,024 pixel resolution of the image sensor. For frame rates faster than 2,000 fps, high-speed
photography is achieved by limiting the read area of the image sensor.

For frame rates faster than 3,500 fps, the resolution is automatically set to the maximum available
at that frame rate. For more details, refer to “5.1.5. Frame Rate and Resolution”, page 56.
3.2. Selecting the Resolution
The maximum resolution of the image sensor is 1,280 x 1,024: total 1,310,720 pixels. You can also
record at even faster frame rates or reduce the amount of image data to make even longer
recordings by limiting the resolution according to the application.

For more information of relation between Frame Rate and Resolution, refer to
“5.1.5. Frame Rate
and Resolution
”, page 56.
3.3. Selecting the Shutter Speed
The shutter speed is independent of the frame rate, and you can control the exposure time in one
frame using the electric shutter. By making an exposure that is of a shorter period than the frame rate,
high-speed objects can be photographed blur-free.
The shutter speed can be set from 1/frame s to a maximum of 1/100,000 s (approximately 10us).

“5.1.8. Shutter Speed List”, page 62.
