Image size
Select the size of the image to be transmitted to the
computer.
You can select from among the following options.
SNC-CS3N:
736 × 480 (Auto), 736 × 480 (Frame), 736 × 480
(Field), 640 × 480 (Auto), 640 × 480 (Frame), 640 ×
480 (Field), 320 × 240, 160 × 120

(Field), 640 × 480 (Auto), 640 × 480 (Frame), 640 ×
480 (Field), 320 × 240, 160 × 120
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.
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.
(in case of 640 × 480 image)
Image
Select Color or Monochrome.
Area setting
When the image size is 736 × 480 or 640 × 480 for the
SNC-CS3N, or 736 × 544 or 640 × 480 for the SNC-
CS3P, you can trim a portion of the image and display
the trimmed image on the computer. With the trimming,
the transmitting data size, and thus, the network load is
reduced and a higher frame rate is obtained.
Select On for trimming the image, or Off for no
trimming.
