Which consequence occurs in Alhazen's pinhole camera obscura when the aperture size increases excessively?

💡 Explanation

Increased aperture diameter allow many more rays of light through. Image blurring becomes significant due to increased angles of incidence, therefore decreasing resolution, rather than improving clarity, because each point in the scene corresponds to a larger patch in the image.
