Disclosed are compounds exhibiting sufficient herbicidal activity at low application dosage when they are applied to soils and foliage, and an agrochemical composition using the same, in particular herbicides. Task of the invention is to establish a compact image formation unit with a broad application range regarding its usage, the sequence in time and variation in time of the process steps. A facial video sequence including the photographer’s face is extracted from the second digital video sequence, and inserted into the low-interest spatial image region in the first digital video sequence to form the composite video sequence.
