Pc-Check Windows Video Capture Image Quality Test Failure Information

Group Number 590X

Device Video Capture

This is a test group for capture devices. Capture devices receive data from items such as video cameras, DVD players or television antennae. The group consists of ten tests that can be run on a device. Included with the group are five tests that check basic functionality, the Capture Driver tests.

If a device is found, it is scanned for the different types of input it offers. If the inputs detected are of an unrecognised type then the Capture Driver Test can then be run to ensure basic functionality.

If the device only offers one video input, only the Capture Test is made available. If the device offers different inputs, the Group offers a test for each of the available inputs.

These tests facilitate performing a high-quality check of the device and its configuration by interactively checking the actual data received.

Test Number 321

Image Quality Test

This test will scan the live video signal for valid QR codes. These codes will be decoded and checked against a configured validation string. If a valid string is found the test will pass with no user input required.

If the test is run in calibration mode, the test will become a interactive test. The live video signal will be displayed and a box will locate any detected QR codes to allow the test image to be placed in the environment in focus. A button will be present to produce the QR code required for the supplied validation string.

NOTE: The QR code to be tested will need to be printed and placed in a location within the video feed.

NOTE: Higher grid settings will increase the time it takes to sample each image but will improve the detection of smaller QR codes.

PARAM1: Use the preview pin

Whether the capture pin (default) or preview pin should be used.
