Abstract: An image processing apparatus includes a detection unit that detects an area of a target object from an image captured by an image capturing apparatus, a first model generation unit that generates a front surface model representing a front surface of the target object based on the area of the target object, and a second model generation unit that generates a back surface model representing a back surface of the target object based on points provided by movement of a plurality of points on the front surface model by a distance corresponding to a thickness of the target object in respective normal directions.

Abstract: A discharge lamp lighting apparatus has a configuration including a control unit which discriminates, for each polarity of an AC rectangular wave output, the output voltage detected with an output voltage detector for detecting the voltage applied to a discharge lamp, and carries out constant power control for each polarity separately. By thus detecting the output voltage for each polarity separately and by outputting a target current for each identical polarity, it can carry out constant power control positively even if the output voltage varies for each polarity, thereby being able to prevent current feedback to a different polarity, and to prevent power oscillation and partial reduction of electrodes due to an increase of the output voltage difference for each polarity.
