Chapter 11 Image Capture Function
11.1 Function Outline
The GT20Q-SB scanner is equipped with an image capture function. Scanned images can be output in either BMP (bitmap
file) format or as a JPEG (standard, high, or low quality).
Image size can be selected from Standard WVGA, 1/4 WVGA and 1/16 WVGA. When 1/4 WVGA or 1/16 WVGA is
selected, users can select whether to enlarge the image to fit the screen, or to extract the center portion of the full screen
(1/1WVGA).
When "enlarge the image to fit the screen" is selected, the visual field becomes wider, but at the cost of image quality
deterioration. When "extract the center portion of the full screen (1/1 WVGA)" is selected, the visual field becomes narrower,
but the quality of the image does not deteriorate.
An image transfer function allows the image to be made into a thumbnail for ease of selection. Thumbnail size can be selected
from 1/64 WVGA in bitmap format and 1/4 WVGA in JPEG format.
Parameters such as output format, image size, image format, and whether to create thumbnails can be changed via the image
output settings command [IMAGEOUT].
Note: The image capture function cannot be used when HID (Human Interface Device Profile) is selected.
