Frame is suitable for still images, and Field is suitable
for animation.
If you select Auto, the image mode changes between
Frame and Field automatically: Frame when the
subject is a still object, and Field when the subject is
moving.
Image quality
Select the image quality from Level 1 to Level 10.
A higher level gives a higher image quality, but the
frame rate decreases as the data size increases.

The following table shows the relation between the data
size of a 24-bit image (8 bits for each R, G and B), and
the compression rate for each Level setting.

When the image size is 736 × 480 or 640 × 480 for the
SNC-RZ30N, or 736 × 544 or 640 × 480 for the SNC-
