5. Digital Camera
Digital cameras are other examples of input devices, most common in the world today.
A digital camera is a photographic input device in which the image or video is recorded on a CCD system and stored in digital form in memory cards. It can not only capture and digitize an image but also record sound and shooting parameters.
The digital camera allows us to take a photograph and immediately create a document in standardized formats for the computer or other devices. The digital camera uses its CCD sensor or Charge Coupled Device as its focal plane.
The cameras are used by both people who are interested or not in photography to capture memorable moments and professional photographers.
Advantages of digital camera
- Images recorded (input) with a digital camera can be displayed on the screen immediately.
- Thousands of photos can be stored in a small memory card.
- To free up space in it, stored images or videos can also be deleted.
- In some digital cameras, it is also possible to crop images as required.
Another computer input device’s examples are scanners. A scanner is a digital input device that is used to scan hard copy images, printed text, and objects and then convert it to a digital format.
How we use the printer to extract prints in different colors. Similarly, we can scan any documents to save on the computer.
It is also known as the Xerox machine. Image scanners are used in a variety of domestic and industrial applications such as design, gaming, reverse engineering, and testing.
Since the document converts into an image in digital form so that it can store on the computer or can be edit, its best advantage is that the user does require to type the information. The possibility of errors in capturing such information has been reduced.
7. Bar code Reader
A barcode reader device is used to input data from a barcode. It is used to read the bar code printed on any product by code bar. Barcode reader detects existing data in barcodes by hitting beams of light on barcode lines. In such a way, information obtains.
Barcode systems and readers proved to be very helpful in businesses. With the help of a barcode, big companies can track their products. You can quickly know the Prices and Stocks Level from the bar code. Companies use this in their Computer Centralized System to increase their efficiency and productivity.
The Barcode Scanner scans the data that can be saved very quickly on the computer. This saves both time and physical exertion. And the chances of mistakes have been reduced. Barcode scanners are examples of input devices used mostly in commercials.
The full form of OCR is “Optical Character Recognition“. OCR is a technology used to read numbers, letters, or symbols in digital format.
The characters and symbols can read through the light source. OCR is commonly used to recognize text by scanning documents in digital form. You can check to live here Online OCR.
