At present, high end megapixel cameras can be up to around 8-megapixel.

The HD format has worked well in forcing camera manufacturers to increase processing power and the potential of their IP cameras but conversely it may also begin to limit the development of megapixel cameras. With HD televisions also conforming to the standard, video output can be made to any HDTV without cropping or resizing. The HD format was created to try and standardise the video transmissions of megapixel cameras. This is more expensive but provides a much clearer and crisper image. The HD standard requires that frames are progressively scanned. This can be manufactured cheaply but often causes blurred images when fast-moving objects are in view. In the first frame, they capture lines 1, 3, 5, 7 etc with the second frame capture lines 2, 4, 6 etc. This essentially uses two frames to create the image. Megapixel camera manufacturers have often used interlaced images to create megapixel footage. The HD standard requires footage to be created at 25 or 30 frames per second depending on location, for example the US runs at 30 frames per second while the UK runs at 25. This has largely been due to processing power available on IP cameras as well as network restraints. Until recently, megapixel cameras have offered very low frame rates compared to low resolution cameras, sometimes offering as low as 4 frames per second compared to 30 frames per second. This is the biggest advantage to HD cameras over megapixel cameras. Similar to the image size, the aspect ratio of HD cameras is 16:9 whereas other megapixel cameras cameras offer a variety of formats such as 4:3. Image quality from HD cameras is therefore not as detailed as some other megapixel cameras. Conventional megapixel cameras often have a number of megapixel resolutions to choose from.

There are two main resolutions for the HD specification, 720p (1280×720, just less than 1-megapixel) and 1080p (1920×1080, 2.1-megapixel). incredible videos.5395 O TRUEVISION Bravado am is its FustNlurdeble SJRS. The HD specifications must all be met in order for a camera to be classed as an HD camera. HD cameras are just a special from of megapixel cameras which conforms to certain specifications laid out by the Society of Motion Picture and Television engineers (SMPTE). However, more recently there have been a number of cameras offering HD quality video footage in addition to their megapixel cameras.ĭon’t think of megapixel and HD cameras as being two separate entities.

Over the last year there has been an explosion in the number of manufacturers offering megapixel cameras, with many reaching over 3-megapixel. What are the differences between HD and megapixel cameras?
