Abstract: An image pickup apparatus includes an image capturing unit, a projection unit, a reproduction processing unit configured to perform processing for reproducing image data, and a control unit configured to switch between operation modes at least including an image capturing mode in which the image capturing unit performs image capturing and a reproduction mode in which the reproduction processing unit performs reproduction processing. When the operation mode is switched to the reproduction mode, the control unit starts activation processing for activating the projection unit.

Abstract: A method and apparatus are disclosed for efficient endothermic processing of liquids and the precipitation of dissolved elements and chemical compounds. Improvements over prior systems include system layout, components and modes of operation of the system. Applications of the system include destruction of toxic wastes and sewage treatment, precipitation of chemical compounds and elements including metals from solution (brine, sea water, industrial waste), sterilization and water purification, catalytic formation of chemical compounds, and processing of hydrocarbons.
