API, OpenAPI and WebMCP documentation

Explanation

Smartphone 1/1.7" class uses crop factor 4.55 and sensor width 7.9 mm. focal_mm = 7.9 / (2 x tan(HFOV/2)). For input 1 deg, output is 452.625168011 mm.

Method & Sensor Profile

Sensor basis: Smartphone 1/1.7" class profile with crop factor 4.55 and sensor width 7.9 mm.
Profile reference: focal-length and aperture equivalence use the same crop model, while angle-of-view routes use the same fixed sensor width geometry.
Consistency rule: forward and reverse pages keep the same sensor profile; only the formula direction changes.

Questions & answers

Frequently Asked Questions

Which sensor assumptions are fixed for horizontal angle of view (degrees) to focal length mm?

Horizontal angle of view (degrees) to focal length mm is fixed to Smartphone 1/1.7" class, crop factor 4.55, sensor width 7.9 mm.

How do I reverse deg to mm for Smartphone 1/1.7" class?

Use the opposite-direction page for Smartphone 1/1.7" class to convert focal length (mm) back to horizontal angle of view (degrees) with the same sensor assumptions.

Can horizontal angle of view (degrees) to focal length mm replace full lens-design simulation?

No. Horizontal angle of view (degrees) to focal length mm provides framing and geometry approximations, not full optical-model behavior.
