Question

The increase in effective brightness due to the size reduction of the output image size is referred to as:

1. output gain
2. minification gain
3. total gain
4. electronic gain

Answer 1

Minification gain refers to the increase in effective brightness due to the size reduction of the output image size.

Step-by-step explanation:

The increase in effective brightness due to the size reduction of the output image size is referred to as minification gain. When the output image size is smaller than the object, the image appears brighter because the same amount of light is concentrated in a smaller area, resulting in a higher brightness. This concept is important in fields such as photography and microscopy, where reducing the image size can enhance clarity and detail.
