resolution of camera in win ce

amin
hi, i want use a camera in a full screen application in mini6410 with lcd
4.3 (480*272). i find a sample code for change resolution using
CCaptureFramework library. this code use GetNumberOfCapabilities to find
Capabilities of device that maximum returns (320*240) as supported
resolution for my device(with or without connecting camera). can i have a
good picture with (480*272) resolution in this situation?
