Office camera

Office camera is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Office camera rather than just read about it. In short: 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. It is similar to the document camera, which is normally used on podiums in classrooms and meeting rooms for presentations.

Key takeaways

Office camera belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Office camera to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Office camera from memory before moving on to harder problems.

Reference excerpt

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. It is similar to the document camera, which is normally used on podiums in classrooms and meeting rooms for presentations. An office camera typically has a compact form factor in order to be a commonplace desktop item. Commercial products, such as the HoverCam, can fit into pockets or briefcases, which makes them ideal for use on desktops or on-the-go. Generally, office cameras have least one high-resolution camera, which can be used in an "aerial" position to shoot video or still image pictures of documents or objects. In order to capture images with enough clarity, such cameras are expected to have high resolution, normally more than 2 megapixels at the minimum, and ideally produce distortion-free images for documents, even when the document contains fonts under 7-point size. A secondary camera, which captures video horizontally to include the presenter(s) of the document or the audience of a presentation, can be beneficial to the device as well. Office cameras can be connected via USB 2.0 ports to a laptop or a desktop computer to function almost similarly as a web camera. Once connected this way, software applications, such as Skype or GoToMeeting, interface with an office camera in the same fashion as connecting with any Universal Virtual Computer device. At the same time, an office camera can have VGA or HDMI video output to a TV or video projector, so that it can serve as a video presentation tool. Capturing still images and recording video footage into a local storage on the device is also possible. Applications of office cameras can include quick "scanning" of documents (which is an alternative to flatbed scanners), showing real-time video of product demos, serving as a video input device for a multiple party video conference with shared interactive whiteboard, capturing images for manufacturing and inventory management, a video testimony, form or invoice scanning and recognition, receipt capturing, expense and report generation.

Worked examples

Example 1 — a first encounter with Office camera

Start with the simplest possible case. Write down what Office camera claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Office camera before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Office camera ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Office camera

In research: Office camera appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Office camera in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Office camera is common in secondary-school and first-year university syllabi. It links to neighbouring topics Digital cameras, so understanding it makes those chapters shorter.
In everyday life: Look for Office camera outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
