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.
Tip
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.
