A1.20
Pupil regulation and light intake
Cards in this group · 5
- A1.20.1Pupil diameter automatically contracts and dilates with ambient light to regulate incoming light
- A1.20.2Pupil adjustment is slower than the brightness jumps electronic displays can produce
- A1.20.3Pupil size also sets depth of field, with a smaller pupil raising tolerance for focus error
- A1.20.4Pupil response is also driven by cognitive load and emotional arousal, not light alone
- A1.20.5High-contrast scenes create competing demands on pupil size, producing local over- or under-exposure
