Resolution of a camera

What is the resolution of a camera?

The resolution of a camera is the number of pixels that make up an image and indicates the amount of detail that the camera can capture and that it will be possible to view. The first value indicates the width, while the second the height of the image. A higher resolution value means higher image quality.
Below we indicate the acronyms used and the relative reference resolution.

  • Quarter Video GraphicsStandard Definition (QVGA): resolution of 320x240 px;
  • Video Graphics Array (VGA): 640x480 px resolution;
  • Wide Extended Graphics Array (WXGA): 1280x800 px resolution;
  • Super Extended Graphics Array (SXVGA): resolution of 1280x960 px;
  • Standard Definition (SD): 640x480 px resolution (commonly referred to as 480p);
  • Wide Ultra Extended Graphics Array (WUXGA): resolution of 1920x1200 px;
  • High Definition (HD): variable resolution between 1280x720 px (720p); 1920x1080px (1080p); 2560x1440px (1440p); 3840x2160px (4k);
  • Ultra High Definition (UHD): 7680x4320 px resolution (commonly referred to as 8K).
The resolution of a camera can also be expressed in megapixels (MP) and indicates the number of pixels that the camera is capable of capturing. A 5MP camera will capture 10,000,000 (10 Million) pixels.
