Nowadays, digital cameras have become very familiar to human life. They appear on most smart electronic devices such as phones, computers, cameras… However, many people wonder about this device: “is a digital camera an input or an output device?” Both are answers to this question.
What is a digital camera?
A digital camera is known as a device of hardware that is usually used to photograph and store images. They are converted to data and stored on a memory card. Differ from an analog camera.
It uses digital optical components. These components are responsible for adjusting and controlling the intensity and color of the light, then turn it into data of pixel.
Not only taking pictures, but many types of digital camera can also record videos. As a result, it can be considered both an input and output device (I/O device) for many reasons below.
Is a digital camera an input or output device?
A digital camera can be considered as an input device since the user uses it to input data into a computer. Moreover, it also allows users to put digital (images) into the computer.
A digital camera takes in documents being given, then creates the desired result. But then the user uses it to produce images to send to the computer. When cameras were the only film, they were just input devices.
But now, they work for both two functions. The reason is that many cameras also connect to WiFi to send photographs wirelessly to the computer. Users can view what picture you just took, then make it an output device you just input pictures into.
Cameras also take in video and export it to the world. But if users do not do some actual inputting, there is nothing to export, unlike some devices such as a printer, a printer is not able to make anything the user did not already produce elsewhere.
Why is a digital camera an output device?
A digital camera can be an output device (for instance, in case the user-edited a photo and saved it back from the computer to the camera’s memory card, it would be an output device), though most people tend to use a digital camera to bring photos in.
Besides, some users have used it the other way and occasionally even transferred none image info onto the memory card.
Summary
From the above reasons, users can draw out that a digital camera is a device that is both an input and an output. It is the answer to “is a digital camera input or output?”
