Using the Video Functions
Capturing a Still Image
This example describes how to capture a still image that has the
following characteristics:
Frame size
320 pels by 240 pels
Color (bit depth)
RGB 24-bit
Important
Be sure your video source (such as a VCR or video camera) is
correctly connected to your computer before you capture the still
image. If you choose Overlay Mode from the Options menu in
DVP Capture, you can verify the connection and look at your still
image before you capture it.
To capture a still image:
1
Start DVP; then choose Video Capture from the Tools menu.
2
Choose Video Format from the Options menu; then choose
320 by 240 for Input Dimensions and RGB 24-bit for Input
Format, and click on OK.
For the best color display, make sure that you install and
choose the 65536 (16-bit) video display driver. As a rule, the
color depth of your image should match the color depth of the
device that will display it, so you would display an 8-bit image
on an 8-bit display device and a 24-bit image on a 24-bit
display device. However, 24-bit images also look good on
16-bit displays (though they tend to display a little more slowly
than on 24-bit displays).
Note:
Because many paint programs, such
as Windows Paintbrush, do not yet
support 16-bit still images, you will
typically capture 8-bit or 24-bit still
images.
