Definition of Resolution
In computing, the concept of resolution may refer to images or a screen or monitor, but in any case relates to the quality of the image that is reproduced to be perceived by the human eye.
The screen resolution is defined by the number or quantity that can be displayed in it. That means more pixels, more resolution and hence better image quality. This type of resolution is the product of the relationship between rows (Y) and columns (X) of the monitor.
Moreover, the image resolution also refers to the level of detail and definition that can be seen in a digital image. This type of resolution is highly discussed in digital photography, as both teams as the cameras capture and image reproduction quality and price based on the level of resolution they provide.
If we intend to know what the resolution of our digital camera, we have far pixels wide and high that you can get a picture. This calculation will give a value that is measured in megapixels.
Depending on the application we want to give the digital capture device, we take into account their quality resolution.
In addition, on a computer, the resolution of the image also has to do with its format. For instance, an image in Jpeg format often has lower resolution and therefore quality, compared to one in Bmp format. This also affects the size and spacing that the image takes on the hard disk of the computer. A larger picture and a higher resolution can take much more space than the same image in a lower visual quality.
