San Diego, CA, United States, 2005/11/15 - A new digital document camera (a common piece of equipment in training rooms, class rooms and courtrooms) with a frame rate approaching 30 frames/second is now shipping. The faster frame rate means smoother images, and better looking presentations.
Alliance International, a manufacturer and distributor of audio-visual equipment based in San Diego, CA, has introduced a digital document camera featuring a new camera element with a refresh rate approaching 30 frames per second. The faster refresh rate eliminates blurry images that afflict digital document cameras with slower refresh rates.
Up to now, most digital document cameras have been in the range of 15 - 20 frames/second, resulting in blurry images when objects are moved.
The Justice Visions JV-850K is a professional class document camera incorporating a progressive scan CCD camera with 850,000 pixels, 16X optical zoom (plus 10X digital zoom), USB 2.0 image capture, and a plug-in mouse for annotation and controlling image functions.
"The unique feature of the JV-850K is the fast refresh rate," said Craig Justice, President of Alliance International. "The images are so smooth that the camera can be used as a regular video camera, which is a great benefit for schools."
"Over the years, I’ve heard many presenters complain about ‘seasickness’ and slow motion typical of digital document cameras," Justice said. "The JV-850K solves that problem."
Other features of the JV-850K include a rotating camera head, full backlight for showing transparencies, RS-232 connectivity, electronic image flip and a remote control with a pop-out remote control slot. The camera has an internal memory of up to 16 images with picture-in-picture capability and various split-screen possibilities. Images may be saved to the computer with a USB cable.
The JV-850K, with its rotating camera head and fast refresh rate, is particularly useful for science teachers who want to show live experiments and for art teachers who want to show drawing techniques without blurring. The camera may be pointed at large objects that do not fit on the camera stage. Teachers may use it as a video camera in the room to project large screen images of students making a class presentation.
The fine silver and black finish of the product makes it suitable for corporate conference rooms, video conferencing and courtrooms.
Document cameras, sometimes called visualizers, are connected to data projectors or large screen monitors to show live, big-screen images of books, papers, transparencies, objects and people. The products are often found in courtrooms, college lecture halls, K-12 classrooms and corporate meeting rooms.
The JV-850K, distributed by Alliance International, is available now through professional AV integrators and education specialists.
