WolfVision Visualizer systems (also known as document cameras) are special optoelectronic devices designed to pick up images of 3-dimensional objects, documents, books, photos and other items from a non-reflective working surface, providing a high resolution output signal for video/data projectors, monitors, interactive whiteboards or ...
Document cameras, also known as visual presenters, visualizers, digital overheads, docucams, or simply doc-cams, are high-resolution, real-time image capture devices used to display an object to a large audience, such as in a classroom or a lecture hall. A webcam is mounted on arms to operate a document camera, allowing it to be positioned over ...

The left half shows the photo as it came from the digital camera. The right half shows the photo adjusted to make a gray surface neutral in the same light. In photography and image processing , color balance is the global adjustment of the intensities of the colors (typically red, green, and blue primary colors ).
An office camera is a digital camera device that performs tasks in offices such as document scanning, physical object imaging, video presentation and web conferencing. [1] It is similar to the document camera , which is normally used on podiums in classrooms and meeting rooms for presentations.
The filesystem in a digital camera contains a DCIM (digital camera images) directory, which can contain multiple subdirectories with names such as "123ABCDE" that consist of a unique directory number (in the range 100…999) and five alphanumeric characters (or any valid filename characters), which may be freely chosen and often refer to a camera maker.
The camera encodes its rendered image into the JPEG file using one of the standard gamma values such as 2.2, for storage and transmission. The display computer may use a color management engine to convert to a different color space (such as older Macintosh's γ = 1.8 color space) before putting pixel values into its video memory.
Medium format cameras use 120 film, which yields a strip of negatives 60 mm wide, and large format cameras capture each image on a single sheet of film which may be as large as 20 x 25 cm (8 x 10 inches) or even larger. Each of these photographed images may be referred to as a negative and an entire strip or set of images may be collectively ...
