Decide whether to manually specify the exposure time
(only recommended for advanced users with difficult image
capture situations).
Only applies when
disabled.
Exposure Time controls the amount of time the CCD is
allowed to collect light, much like the shutter speed for
a camera. Generally, the brighter the environment, the
lower the exposure time. Increasing the exposure time
past 20 ms in a handheld application increases the risk
of blurring the image due to hand jitter.
Set the manual exposure time in the range of 1ms,
10ms, 20ms, 30ms, 40ms, 50ms, 60ms, 70ms, 80ms,
90ms, 100ms.
Decide whether to project the aiming pattern while
capturing an image.
Decide how to alter image resolution before compression.
Multiple pixels are combined to one pixel, resulting in a
smaller image containing the original content with reduced
resolution.
752×480 (Full resolution)
376×240 (Half resolution)
188×120 (= 1/4 resolution)
Decide in which file format the image is saved.
JPEG file format
BMP file format
Decide whether JPEG images are optimized for quality.
Cancel the check box so that JPEG images are
optimized for size.
Set a value from 5 to 100, where "100" represents the
highest quality image.
Set a value from 5 to 150, which represents the file size in
multiples of 1024 bytes (1K). For example, setting this
value to 8 permits the file size to be as large as 8192
bytes.
Select the number of significant bits per pixel (BPP) to use
when capturing an image.
1 bit per pixel (for black and white images)
4 BPP (to assign 1 of 16 levels of grey to each pixel)
8 BPP (to assign 1 of 256 levels of grey to each pixel)
