ISO 12231-1:2025 - Digital imaging - Vocabulary - Part 1: Fundamental terms is an ISO/TC 42 vocabulary standard that defines and clarifies core terms used across digital imaging. This second edition updates and extends the list of commonly used fundamental terms, removes obsolete entries, and provides a consistent, English‑based word order for terminology. The document contains no normative references and includes an informative Annex A that maps related working groups and ISO deliverables in digital imaging.
The standard provides clear definitions for foundational digital‑imaging concepts, for example:
Definitions cite related ISO standards (e.g., ISO 12233, ISO 12232, ISO 20462‑1) when appropriate, helping readers link vocabulary to measurement and test methods.
ISO 12231-1:2025 is a reference for anyone who needs consistent terminology in digital imaging:
Annex A lists WGs and related ISO deliverables (examples: ISO 12233, ISO 12232, ISO 20462‑1, ISO 22028 series). Those documents provide measurement methods, test procedures and encodings that complement the vocabulary in ISO 12231‑1:2025.
Keywords: ISO 12231-1:2025, digital imaging vocabulary, fundamental terms, image sensor, aliasing, Nyquist limit, pixel aspect ratio, image quality, resolution, ISO standard.
