Internertional Association for Healthcare Security and Safety (IAHSS) Advanced Officer Certification Practice Exam

A megapixel camera increases the resolution to between which values?

1. 1 x 2 and 1 x 4

2. 4 x 8 and 4 x 16

3. 8 x 16 and 16 x 32

4. 32 x 64 and 64 x 120

The correct answer is: 8 x 16 and 16 x 32

The choice that pertains to the typical resolution range of a megapixel camera, which usually refers to images that consist of millions of pixels, is often associated with higher values. Megapixel cameras are noted for their ability to capture detailed images, with common resolutions starting from 1 megapixel (1,000,000 pixels) and going up to 16 megapixels and beyond, typically measuring in dimensions that align with the selected answer. For instance, a camera with 8 megapixels typically captures an image resolution around 3264 x 2448 pixels, whereas a 16-megapixel camera can capture around 4928 x 3264 pixels or higher. These dimensions fall within the range indicated in the chosen answer, reflecting the progressive increase in pixel density and image quality associated with advancing camera technology. This choice effectively represents a more realistic understanding of the megapixel concept in relation to image resolutions compared to the other options provided, which suggest lower or unusual combinations that are not typical of standard megapixel camera specifications.
