Hp Truevision Hd Webcam Resolution Windows 10 Or WindowsIf you are not using the latest version of Windows 10 or Windows 8, some graphics and information in this document might vary. Certain HP notebook and All-in-One computers come with built-in webcams that you can use to capture video motion or still images. A webcam is a video input device, similar to a scanner or camera, and requires software to function. The two most common types of software that use webcams are Internet messaging software (for making video calls over the Internet), and video editing software (for creating and sharing video files). Webcams fall into an ill-defined area between digital cameras and video camcorders. Today, webcams have the ability to take both great quality pictures and to capture high-definition video. Due to webcams falling in this grey area, there is no set standard for how to describe each webcams capabilities. One webcam may be listed as 2.0 megapixels and another as 1080p. This webcam has a normal aspect ratio, but this one has a 16:9 aspect ratio. At this point, you may be wondering, like the Double Rainbow Guy What does all this mean Below, we cut through confusing tech jargon so youll know exactly what each camera can do. For example, 720p really means 1280x720 pixels, where 1280 represents the number of horizontal pixels and 720 represents the number of vertical pixels. A 720p television will progressively scan 921,600 pixels (1280x720) on the screen every 160 of a second. The more pixels that can be progressively scanned onscreen, the better the video quality. Taking our last example of 1280x720, or 921,600 pixels, this would come to.9 megapixels (MP), or one megapixel if you round up (mega means one million). As you can see, the formula to arrive at both descriptions of resolution are exactly the same, just described differently. There are two main reasons why webcams are either described in megapixels or in HD resolution. The other reason for the two different descriptions for video resolution is a separate measurement: the aspect ratio. When it comes to a webcam that has a normal aspect ratio, you are more likely to see the resolution listed in terms of megapixels. When you see a webcam for which the video resolution is listed in megapixels, expect the picture to be as tall as it is wide. Webcams that are VGA are not considered high-definition webcams. These are entry-level webcams that shoot video at a resolution of 640x480 pixels, or.3 megapixels or below. This type of webcam comes from an early technology, whereas most high-definition webcams now have CMOS sensors.
