Which optical outcome increased accuracy in al-Haytham's pinhole camera obscura?

💡 Explanation

When passing light through a small pinhole, reduced chromatic aberration occurs because the smaller aperture minimizes the dispersion of light into different wavelengths within the field of view, resulting in a somewhat sharper image. Therefore, reducing chromatic aberration improved sharpness, rather than brightness, contrast or light collection for image formation, where different components are required.
