A digital camera has an electronic sensor that allows images to be digitized and stored in memory.
The notion of camera can be used in various contexts. Today we will stick with its meaning as the machine used to take photographs. Digital , on the other hand, can refer to the system that works as information through discrete signals, such as letters or numbers.
A digital camera is a camera that uses an electronic sensor to digitize images and save them in memory . This differentiates these cameras from analog cameras.
Features of digital cameras
The first cameras used a physicochemical process to record images. They were recorded on a roll or reel that then had to undergo an action known as developing , which allowed the photos to be captured on paper.
Digital cameras, on the other hand, save photos as digital data in memory . The user has the possibility of storing the images on the same camera or saving them on different digital equipment: a computer (computer), a USB memory, etc. In any case, it is possible to print the photos to have them on paper.
Digital cameras generally allow you to record not only photos, but also videos and sounds . The quality of the documents generated is usually measured according to the number of pixels, although there are other factors that must be taken into account (such as sensitivity and sensor size).
Digital cameras have a screen to view the photographs that have already been taken.
Advantages and disadvantages
In addition to all of the above, we have to point out that if in recent years the digital camera has become the favorite of many users, it is because it brings with it a notable series of advantages such as these:
– It has a large storage capacity, so hundreds of photographs can be saved.
– It represents a saving in that it does not require frequent purchasing of reels to be able to take snapshots.
– When it comes to printing one or more images that are saved in the camera, it is much easier than doing so with a traditional camera. And they can be taken on a pendrive to the photo store or they can even be printed at home from the printer.
– It has a series of really interesting features such as deleting photos that have not turned out well or that you no longer want to have, seeing on the screen the photographs that have been taken and some models even include small editors. These allow you to retouch them to a certain extent, establish the date and time they were taken, crop them...
– In the same way, the digital camera includes useful systems such as automatic shooting, burst…
– Despite the long list of advantages of digital cameras, we must not overlook that they also have their disadvantages. Thus, we can highlight the fact that they soon become obsolete because technology advances very quickly or that they have a higher price than “traditional” ones.
The webcam, a digital camera
Among digital cameras we can mention the webcam .
This device is specially designed to work connected to a computer and perform video conferences or live broadcasts via the Internet.
