3.2. Selecting the Frame Rate
With the system, you can record images from 60 (50) to 1,080 fps using the full 2,048 x 2,048 pixel
resolution of the image sensor. For frame rates faster than 1,080 fps, high-speed photography is
achieved by limiting the read area of the image sensor.
• The minimum frame rate in NTSC mode is 60 fps.
• The minimum frame rate in PAL mode is 50 fps.
• For frame rates faster than 1,080 fps, the resolution is automatically set to the maximum available
at that frame rate. For more details, see "5.1.4 Frame Rate & Resolution", page 54.
3.3. Selecting the Resolution
With the system, you can record images with a maximum size of 4,194,304 pixels using the
high-speed image sensor, which has a maximum size of 2,048 x 2,048 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.
The recording time when the horizontal resolution is set to 1,920 is the same as when the
horizontal resolution is 2,048.
Example: The recording time is the same for a 2,048 x 1,536 pixels resolution and a 1,920 x
1,536 pixels resolution.
• For more information on the relationship between frame rate and resolution, see "5.1.4 Frame Rate
& Resolution", page 54.
