Sensor pixel pitch

Pixel pitch is the physical spacing represented by each active pixel along a sensor dimension.

For example, a 36 mm-wide sensor with 6000 active horizontal pixels has a 0.006 mm pitch, or 6 µm.

Why pixel pitch matters

Photivra uses pixel pitch to convert physical image-plane distances—such as projected object size, defocus, diffraction, subject motion, and camera shake—from millimetres into sensor pixels.

Model limits

The calculation assumes the supplied physical sensor dimension and pixel count describe the same active dimension. It does not infer photosite geometry, microlens behavior, color-filter layout, or effective resolution.
