Pixels

In computer science or digital photography, an image consists of a set of dots called Pixels. These pixels are the smallest building blocks of a digital image. Short Px, the pixel name comes from an English term Picture element which means image element. The pixel takes the form of a rectangle that is closer to a square. Its sides are usually between 0.18 mm and 0.66 mm. In terms of display, The pixel is associated with a color or intensity. The variation in the intensity of each pixel allows you to display thousands of different colors.

On the other hand, pixels help determine the resolution and definition of an image's display. The amount of pixels defines the resolution which is expressed in points per inch (dpi), an inch representing 2.54 cm. If taken, for example, a resolution of 300 dpi would correspond to 300 columns and 3000 rows of pixels or 90,000 pixels on a square inch. 

In digital photography, whether it is a Mini Camera whencespy camera clock, the most commonly used unit of measurement is the megapixel. This corresponds to 1000 x 1000 pixels. Moreover, the definition of an image is also determined by pixels. Definition being the number of points constituting an image or the size of the image. The VGA display is, for example, a definition of 640 x 480. This corresponds to 640 pixels in width and 480 pixels in height. Devices such as the spy camera alarm clock HD 720P have a definition of 1280 x 720 pixels.
