Q.25 What is the smallest unit of Image?
- 1 sq. mm
- Pixel
- DPI
- none of these
Solution
The smallest unit of an image is referred to as a "Pixel". A pixel is the basic building block of digital images, representing the smallest controllable element of a picture represented on the screen. Each pixel can be a different color and together they form the complete image.
Let's briefly analyze the options given:
- 1 sq. mm - This is a unit of area and not specifically related to digital images.
- Pixel - This is indeed the smallest unit of an image.
- DPI (Dots Per Inch) - This is a measure of image resolution, not a unit of the image itself.
- none of these - This option is incorrect since "Pixel" is the correct answer.
Final Answer
2. Pixel is the smallest unit of an image.
