Claim:
1. A method, comprising: illuminating a region within a time-of-flight camera system's field of view; determining depth profile information within said field of view using time-of-flight measurement techniques comprising sensing a reflection from the illuminating with a plurality of pixels and measuring a respective time between the illuminating and the sensing for each of the plurality of pixels; determining one or more regions within said field of view where a received signal from said illuminating was weak; re-illuminating said one or more regions with stronger light than said one or more regions received during said illuminating, each of said one or more regions being smaller than said region; and, determining depth profile information within said one or more regions using time-of-flight measurement techniques comprising sensing a reflection from the re-illuminating with a plurality of pixels within the one or more regions and measuring a respective time between the re-illuminating and the sensing of the reflection from the re-illuminating for each pixel within the one or more regions.
