概要	Comparative Visual Analysis is a qualitative research design that systematically examines and compares visual materials — photographs, videos, artworks, advertisements, or digital images — across two or more cases, groups, time points, or contexts. By applying a consistent analytical framework to multiple visual corpora, the approach reveals similarities, differences, and patterns that would remain invisible when studying a single set of images alone.	Comparative Content Analysis applies a shared coding framework to texts, documents, or media artifacts drawn from two or more groups, contexts, time points, or nations in order to identify similarities, differences, and patterns across those units of comparison. By holding the analytical lens constant while varying the comparison unit, it reveals how meaning, framing, or discourse differs across the cases under study.
