What is Difference Between Pixel and Resolution

Pixel vs Resolution

Summary: Difference Between Pixel and Resolution is that pixel is the smallest element in an electronic image. The greater the number of pixels the camera uses to capture a picture, the better the quality of the picture. While Resolution is the number of horizontal and vertical pixels in a display device. A digital camera’s resolution is defined in pixels.

Pixel

A pixel (short for picture element) is the smallest element in an electronic image. The greater the number of pixels the camera uses to capture a picture, the better the quality of the picture. Digital camera resolutions range from about 4 million to more than 16 million pixels (MP).

Usually displays are measured in size(in centimeters and inches). Here we only measure the diagonal size and not the horizontal or vertical size of the screen. There is also another important property of display which is the resolution. Resolution refers to size of the display in terms of pixels. E.g. Resolution of 800×600 pixels means that the there are 800 pixels horizontally and 600 pixels vertically. So therefore there are a total of 480000 pixel in the display.

Pixel is just an element of the picture that plays an important role to complete the image. The word ‘pixel’ was first published by Frederic C. Billingsley in 1965. The measurement of the screen can be described through pixels. Hence, the size of the image also depends on the number of pixels, the larger the number of pixels your image is having the greater the size will be.

Pixel Density

Many of us are not aware of the importance of Pixel Density in displays. It is the thing which describes the sharpness and clarity. Pixel Density is usually measured in PPI (Pixels Per Inch) which refers to number of pixels present per inch on the display. Higher the pixel density higher is the sharpness of the content. Pixel Density is calculated based on the resolution and size of the display.

Pixel Density= Root((Horizontal Number of Pixel^2) + (Vertical Number of Pixel^2))/Screen Size

Resolution

One factor that affects the quality of digital camera photos is its resolution. Resolution is the number of horizontal and vertical pixels in a display device. A digital camera’s resolution is defined in pixels. Resolution is made up of all the elements (pixels) combined together to form a quality image. The greater the resolution is the better you will get the quality of your picture. Resolution describes the elements or pixels in an image. You can measure resolution in three difference ways, Sample per inch (spi, scanners) or Pixel per inch (ppi, monitors) or Dots per inch (dpi, printers).
