What are examples of digital input devices?
In computing, an input device is a piece of equipment used to provide data and control signals to an information processing system, such as a computer or information appliance. Examples of input devices include keyboards, mouse, scanners, cameras, joysticks, and microphones.
What are image input devices?
Summary. The primary digital image recording devices are the digital scanner and the digital still camera. ... The most common desktop scanners record the image data using a row of sensors.
Is a device that uses a light source to read characters?
Abbreviated OCR, optical character recognition devices also use a light source to read special characters and convert them into electrical signals to be sent to the central processing unit.
Which type of light is sensitive?
In someone who is light sensitive, any type of light source (sunlight, fluorescent light, incandescent light) can cause discomfort. Photophobia typically causes a need to squint or close the eyes, and headache, nausea, or other symptoms may be associated with photophobia. Symptoms may be worse with bright light.
What are the light sensitive cell?
The light-sensing cells on the retina are known as photoreceptors. Two important types are rods and cones. Each human retina (and you have two, one in each eye) contains 125 million rods and about 6 million cones.
Is Scanner is a pointing device?
The Scanner is not a pointing input device. A scanner is a device usually connected to a computer. Its main function is to scan or take a picture of the document, digitize the information and present it on the computer screen.
Is a light pen a pointing device?
Light Pen (similar to the pen) is a pointing device which is used to select a displayed menu item or draw pictures on the monitor screen. It consists of a photocell and an optical system placed in a small tube.
What are scanner devices?
