There are a few factors that can affect the size of the projected image: the lens diameter, the focal length, the distance between the lens and the screen, and the size and shape of the screen. In general, the larger the lens diameter, the smaller the projected image will be. Conversely, the smaller the lens diameter, the larger the projected image will be.

The relationship between the lens diameter and the projected image is a function of both optical properties and the viewing distance. The optical properties of the lens, such as its Abbe’s number and its curvature, affect the shape and the intensity of the projected image. The viewing distance, in turn, determines the amount of distortion that is introduced into the image. For example, if the lens has a smaller diameter, the projected image will be more distorted near the edges than if the lens had a larger diameter. This is due to the fact that the smaller diameter lens has more focal points per unit area, and as a result, more distortion is introduced at the edge of the image. In order to compensate for this distortion, the viewer’s brain is forced to compensate by making the image larger in the center. The larger the lens, the less distortion will be present at the edges and the viewer will not be required to make such a compensatory adjustment.
offs of using a larger or smaller lens diameter?
larger lenses have a wider angle of view and produce a higher-quality projected image than smaller lenses. Larger lenses also produce a greater depth of field, which means that they can capture a greater range of detail in a scene.
Conclusion
The relationship between the lens diameter and the projected image is that the smaller the lens diameter, the smaller the projected image.
