In BDM, if image height increases, how does viewer distance change?

In Broadcast Data Management (BDM), the relationship between image height and viewer distance is foundational to creating an optimal viewing experience. When the image height increases, it typically implies that the viewer will move further away from the display to maintain a comfortable field of view and to take in the entire image without strain.

As the image height increases, the viewer’s distance from the screen must also increase to avoid visual discomfort, ensure that the entire picture can be seen at once, and maintain picture clarity. This is essential because larger images require more distance to be viewed effectively, preventing the viewer from needing to move their head or eyes excessively to track different parts of the image.

The other options suggest alternatives that do not align with standard viewing principles. For instance, suggesting that viewer distance decreases contradicts the idea that larger images can overwhelm a viewer's immediate field of vision. Similarly, asserting that viewer distance remains the same or that it varies greatly from person to person detracts from the established understanding of how image size influences viewing distance in audiovisual contexts.
