Pixel: A pixel (short for picture element) is the smallest unit that makes up an image or display. Each pixel is assigned a color and brightness value to create the overall image.
Resolution in Images: For digital images, resolution describes the number of pixels per linear inch (ppi) or per centimeter (ppc).
- A higher resolution image contains more pixels per unit area, resulting in finer details and better image quality.
- The resolution of an image also determines its physical size when printed. For example, if you have an image with a resolution of 300 ppi, it will print at around 300 dots per inch, making it suitable for high-quality prints with good clarity.
Resolution in Displays: In the context of electronic devices like TVs, monitors, and smartphones, resolution refers to the total number of pixels displayed horizontally and vertically on the screen.
- A higher resolution display provides more detailed and sharper images. For example, a display with a resolution of 1920 x 1080 (often abbreviated as "1080p") has 1920 pixels across and 1080 pixels down.
