概要	Visual elicitation document analysis is a qualitative method that uses visual materials — photographs, drawings, institutional images, maps, or archival visuals — embedded within or alongside documents to prompt deeper participant reflection and to enrich the interpretive reading of those documents. By treating visuals as primary analytic objects rather than mere illustrations, the approach bridges visual elicitation (provoking meaning-making through images) and systematic document analysis (examining records for evidence of social, institutional, or cultural processes).	Content analysis is a systematic research technique for reducing text, visual, or media material into coded categories so that patterns can be counted, compared, and interpreted. Formalised by Klaus Krippendorff in his widely cited methodology textbook (latest edition 2018), the method sits at the boundary of qualitative and quantitative inquiry: it imposes structured, replicable coding on inherently meaning-laden material.
