4-4 Using WebCam Control with the VFW driver

Choosing the size 
of the image

Select the desired output size for the image from the Resolution list.

For recording live video, these resolutions are ideal: 160 x 120, 176 x 144, 320 x 240, and 
352 x 288.  These lower resolutions will give you a higher frame rate.
For capturing still images, larger resolutions are more suitable.
WebCam can capture images of up to 640 x 480 pixels in size.

Note that large image sizes require more disk space to store the image files or video clips.
Large image sizes also slow down the frame rate and increase transfer times for downloading 
from or uploading to web pages.

Choosing the 
color depth

Select the desired color depth for the image from the Pixel Depth (bits) and Compression list.
The options available are:

12 ; I420, which is Intel Raw YUV (raw input)

24 ; RGB, which is 24-bit RGB (16.7 million colors)

16 ; RGB, which is 16-bit RGB (65K colors)

Table 4-1 below shows you the color depth modes that are available at each supported 
resolution.
