What is a digital camera?
Digital camera is a small portable electronic device that contains a camera to capture static or video images, storage memory and some control system. These devices may or may not actually resemble a pen. Some models, especially those that are designed to resemble pens, should be used hidden. Other types of digital pen camera are not intended for secrecy, but are designed to be easy to use, very lightweight and portable. Some other types of pen camera are designed for specific tasks and are called pen cameras simply due to their size and shape.
Small spy cameras have a long and turbulent history. The US Central News Agency (CIA) and the Soviet KGB used several models of miniaturized film cameras in an effort to capture photos of sensitive information. Thanks to progress in technology, even a very simple digital camera with a bulk market is favorably compared to the small miraclesCold War technology.
The quality of the mounted in one of these small devices is essential. Digital cameras produce better images and, although more expensive, are usually not much larger than lower -quality cameras. A cheaper digital camera will certainly cost less money, but can produce images that are too granular or out of focus to be useful. Models of better quality capture brighter images.
Many of these cameras are also able to record sound and video. Better and more expensive models usually overcome their cheaper opponents. The quality of the built -in microphone is also important in determining overall performance. The amount of memory available, either as part of the PEN camera system itself, or via a memory card slot, determines how many videos, how many images and how much sound can be recorded.
Key version of the Digital cameraThe pen usually resembles nicer Ballpoint Pen. The relatively wide body of such pens allows space for the necessary lenses, microphones and electronics. The actual part of the pen of these devices is usually able to write, but may not contain enough ink to make it so long.
Less smallest versions are not masked as real pens. They are still very small and portable and conveniently fit in a typical pocket. They can be useful for recording interviews or conversations if there are no need for high quality images and sound.
Digital endoscopic microscope in the digital camera pen is an example of one additional type of digital camera. This device available for home use is called a pen with a pen, because to place the camera using a pen and pen size probe. This camera enlarges and transmits a picture from the tip of the device that allows it to serve as a microscope.
