Abstract: A generation unit generates N distortion corrected images (N?2) by performing coordinate conversion on each of N partial areas of a first captured image, using a conversion parameter that depends on a position of the partial area, and generates N distortion corrected images by performing coordinate conversion on each of corresponding N partial areas of a second captured image, using a conversion parameter that depends on a position of the partial area.

Abstract: A subject (10), such as a billboard, has a filtering film (15) to absorb electromagnetic radiation specifically in a first wavelength band. A detector (60) provides a first detector signal (61a) relating to the first wavelength band and a second detector signal (61b) relating to another, different, second wavelength band, respectively. Suitably, the subject (10) appears with high intensity in one band and with low intensity in the other. A content replacement unit (40) produces a mask signal (43) by identifying regions of contrast between the first and second detector signals (61a, 61b) as target areas (75). A content substitution unit (47) selectively replaces the target areas (75) with alternate image content (42) to generate modified video images (72). The system is useful, for example, to generate multiple live television broadcasts each having differing billboard advertisements.
