When the display field-of-view (DFOV) is increased, what is the effect on pixel size?

When the display field-of-view (DFOV) is increased, the pixel size increases as well. This is because the pixel size is determined by dividing the DFOV by the number of pixels in the matrix. Therefore, as the DFOV expands, the area each pixel represents also expands, resulting in larger pixel sizes.

This relationship is fundamental in imaging; when the area scanned (DFOV) becomes larger while maintaining the same matrix size, the individual pixels must cover more ground, effectively increasing their dimensions. If the matrix size were to remain constant while increasing the DFOV, then for the same number of pixels in the matrix, each pixel must encompass a larger portion of the image, leading to increased pixel size.

Consequently, the other options do not accurately reflect this relationship. If pixel size were to decrease on increasing DFOV, it would contradict the basic principles of how image resolution and size interact with display parameters. Moreover, a scenario in which pixel size is unaffected would misinterpret the spatial relationship between DFOV and pixel distribution. Lastly, while varying pixel size based on matrix size could seem plausible, it doesn't directly correlate with an increase in DFOV specifically; rather, it pertains to decisions made during image acquisition and processing independent of the
