Yes, it can work with normal applications, but they must implement YUYV orĬompressed format handlers, and I don't know why most applications don't.īut think that uvc really works for you, the problem is the native format of As an aside to the main component, Logitech has included a small plastic case which has been specifically designed to house both the camera and the cable, while this is a simple add-on, it's very welcome for the road warrior.Subject: Re: no video using UVC and quickcam notebook pro In testing we tried it out in a number of different situations and the webcam fared well in virtually all of them, coping with working in the garden to a dark room with poor lighting. Selecting the auto option sets up the best settings and for the ardent traveller saves a lot of hassle.
Understandably laptop users are sometimes in different locations and Logitech has included five different white balance settings in an attempt to correct everything from incandescent to fluorescent and daylight settings. Those looking to broadcast in black and white can do so, although we are not sure why you'd want to and the camera also offers horizontal and vertical flipping if your latest webcast is back-to-front and upside down. Delving deeper into the cameras setting reveals the ability to change brightness, contrast, gamma, saturation and exposure settings. Once installed the camera offers to captures footage in three settings 160x120, 320x240 and 640x 480. The web cam itself connects via a USB socket (with fairly long cable) making the whole thing a fairly simple operation to get up and started.ĭrivers, Logitech's video companion software and Yahoo Instant Messenger are included in the box, as well as, version 4 of both MGI's Videowave and Photosuite packages. Encased in a gun metal grey housing that is no bigger than pack of 10 cigarettes, the camera features a focus ring for a obtaining a sharp image, a protective cover for the lens and two adjustable arms so you can hang the device from the top of your laptop or monitor screen. The QuickCam for Notebooks Pro sits firmly as the name suggests in the notebook arena. Since the popularity of both devices has grown, manufactures like Logitech and Creative now offer a “laptop” range as well as the traditional desktop range. Designed originally to sit atop your monitor, the lack or surface on both the aforementioned products causes a problem. (Pocket-lint) - For the laptop or TFT monitor user the conventional web cam doesn't work.
