ISO 12233-2014 pdf free.Photography一Electronic still picture imaging一Resolution and spatial frequency responses. ISO 12233 specifies methods for measuring the resolution and the SFR of electronic still-picture cameras. It is applicable to the measurement of both monochrome and colour cameras which output digital data or analog video signals. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. ISO 14524, Photography 一Electronic sill-picture cameras一Methods for measuring opto-electronic conversion functions (OECFs) 3 Terms and definitions For the purposes of this document, the fllowing terms and definitions apply. 3.1 addressable photoelements number of active photoelements in an image sensor Note 1 to entry: This equals the product of the number of active photoelement lines and the number of active photoelements per line. 3.2 aliasing output image artefacts that occur in a sampled imaging system due to insuficient sampling Note 1 to entry: These artefacts usually manifest themselves as moire patterns in repetitive image features or as jagged stair-stepping at edge transitions.. 3.3 cycles per millimetre cy/mm spatial frequency unit…

ISO 17850-2015 pdf free.Photography一Digital cameras  – Geometric distortion (GD) measurements. ISO 17850 specifies a protocol to measure geometric distortion of a digital camera. It is applicable to the measurement of digital cameras including camera phones. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. ISO 14524, Photography — Electronic still-picture cameras — Methods for measuring opto-electronic conversion functions (OECFs). IEC 61146-1, Video cameras (PAL/SECAM/NTSC) — Methods of measurement — Part 1: Non-broadcast single-sensor cameras EBU Tech3249, Measurement and analysis of the performance offilm and television camera lenses 3 Terms and definitions 3.1 geometric distortion GD <of DSC> displacement from the ideal shape of a subject (lying on a plane parallel to the image plane) in the recorded image Note I to entry: Geometric distortion basically derives from variation of lateral magnification in the image field of a camera lens and results in straight lines being rendered as curves. There are other factors to induce geometric distortion, for example, rotational asymmetricity of a camera lens…
