Which optical phenomenon increases perceived clarity in Alhazen's pinhole camera obscura implementation?

💡 Explanation

The small aperture of Alhazen's pinhole limits the range of angles of light rays passing through, increasing image sharpness via decreasing chromatic aberration caused by focusing inconsistencies of different wavelengths. Therefore reduced chromatic aberration contributes, rather than diffusion, sensitivity, or depth of field changes which require wider light sources or lens curvatures.
