Full title and description

St ISO/TS 19567-2:2019 — Photography — Digital cameras — Part 2: Texture analysis using stochastic pattern. This technical specification defines a protocol and measurement procedures to evaluate texture reproduction in images captured and processed by digital cameras (including cameras embedded in other devices such as camera phones) using test charts that contain stochastic (non‑cyclic) patterns.

Abstract

This document specifies objective measurement protocols for texture reproduction in digital camera images using stochastic test charts. It describes test‑chart design, measurement procedures and reporting conventions and notes that objective texture metrics can sometimes differ from subjective visual assessments (see Annex C of the specification).

Scope

Specifies a protocol to measure texture reproduction in images captured and processed by digital still cameras and cameras in other devices (for example camera phones). The document focuses on measurement procedures using test charts with stochastic (random) patterns and provides guidance for objective evaluation and reporting of texture metrics; it does not prescribe perceptual acceptability limits. The method is intended for objective evaluation and laboratory testing rather than consumer perceptual scoring.

Key topics and requirements

• Definition of test charts and stochastic pattern design for texture measurement.
• Measurement procedures and imaging conditions for capturing test charts with digital cameras.
• Algorithms and metrics for quantifying texture reproduction from captured images.
• Requirements for data reporting and notation of processing steps (e.g., in‑camera processing, demosaicing, sharpening, noise reduction).
• Notes on the relation between objective texture measurements and subjective visual assessments (limitations and interpretation guidance, including Annex C).

Typical use and users

Used by camera and mobile‑device manufacturers, imaging laboratories, test houses, researchers in image quality and vision science, and standards committees to evaluate and compare texture reproduction performance of digital cameras and imaging pipelines under controlled test conditions.

Related standards

Part of the ISO/TS 19567 series; closely related to ISO/TS 19567-1:2016 (Part 1 — frequency characteristics measurements using cyclic patterns). It is used alongside other image‑quality and measurement standards (for example standards addressing resolution and colorimetric behavior such as ISO 12233 and IEC/ISO color/display related documents) when performing comprehensive camera image‑quality assessments.

FAQ

Q: What is this standard?

A: ISO/TS 19567-2:2019 is a Technical Specification from ISO (ISO/TC 42) that defines objective measurement protocols for assessing texture reproduction in images from digital cameras using stochastic test patterns.

Q: What does it cover?

A: It covers test‑chart design (stochastic patterns), recommended imaging conditions and procedures, analysis algorithms and reporting conventions for objective texture metrics; it also includes guidance on interpreting results and notes that objective metrics may not always match subjective perception.

Q: Who typically uses it?

A: Camera manufacturers, mobile device OEMs, independent imaging test laboratories, researchers in image quality and vision science, and standards developers use it to benchmark and compare texture performance of imaging systems in controlled test setups.

Q: Is it current or superseded?

A: The specification was published in July 2019 (with a corrected English version noted in December 2019) and is listed as a published/confirmed ISO Technical Specification; users should check national bodies or ISO for any later confirmations or revisions before use.

Q: Is it part of a series?

A: Yes — it is Part 2 of the ISO/TS 19567 set. Part 1 (ISO/TS 19567-1:2016) addresses frequency characteristics measurements using cyclic patterns; together the parts provide complementary methods for texture measurement.

Q: What are the key keywords?
