Super16 Crop Factor Calculator
Actual Super16 active image DIAGONAL crop factor versus independent reference diagonal, same units. No universally fixed gate dimensions, field height fraction or lens factor prescribed.
Description
Super16 crop-factor comparisons depend on the actual active image diagonal and the chosen reference.
Super16 crop-factor comparisons depend on the actual active image diagonal and the chosen reference.1
This tool calculates their ratio without installing a fixed format size or changing a lens's focal length.
When to use Super16 Crop Factor Calculator
Use this tool to calculate their ratio without installing a fixed format size or changing a lens's focal length.
How to use Super16 Crop Factor Calculator and how it works
- Prepare callerMatchedReferenceImageDiagonal, actualMeasuredActiveImageDiagonal, with the units, conventions and assumptions below.
- Enter the required fields and run Super16 Crop Factor Calculator.
- Read result.value using the output definitions below.
- Correct any rejected inputs and rerun; interpret the result within the stated model and its assumptions.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| callerMatchedReferenceImageDiagonal | Caller Matched Reference Image Diagonal. Use the units and matching context stated in the calculation below. | number | Required; strictly positive; finite; other constraints below |
| actualMeasuredActiveImageDiagonal | Actual Measured Active Image Diagonal. Use the units and matching context stated in the calculation below. | number | Required; strictly positive; finite; other constraints below |
Supply positive reference and measured sensor diagonals in the same length unit. Return reference/measured as a dimensionless crop factor. The caller establishes the intended Super 35 or Super 16 format and reference convention; no sensor specification is built in.
cropFactor=referenceDiagonal/measuredDiagonal Apply the input ordering, units and branch conditions stated above.
| Output field | Meaning | Value type |
|---|---|---|
| result | Object containing the calculated or selected fields below. | object |
| result.value | Dimensionless reference-diagonal to measured-diagonal crop factor. | number |

}Limitations and assumptions
The calculation uses the supplied observations and model inputs. It does not collect measurements, select a reference population or coefficient, or establish that the model applies to the actual case. The stated branch conditions and output units remain part of the result.
All fields require explicit values. Unexpected fields, wrong types, nonfinite numbers and sparse arrays are rejected. Alignment, bounds and supported-token rules are explained above; extremely large inputs or nonfinite results can also fail. Input errors differ from successful false comparisons, unavailable-domain flags and empty match lists.
Alternative or Complementary methods
Use Super35 Crop Factor Calculator for a complementary operation: A diagonal crop factor compares a reference image diagonal with an actual active image diagonal.
Use Open Gate Resolution Calculator for a complementary operation: Open-gate dimensions describe the full sensor geometry under a specified binning convention.
