Video frames of original video data are sampled with arbitrary time interval and size, and thumbnail frames are obtained. This gas can be burned in an engine, turbine, oven or boiler, which makes it possible to valorize the thermal energy that it harbors. The connection region has the same conductivity type as the sourcedrain regions to increase the channel conductivity. A die, or active optical device, with one or more active optical elements on a first die surface and electrical contacts on a second die surface, is aligned with the electrical pads of the substrate and the active optical elements. In the image pickup apparatus, the light-beam splitting mirror has spectral characteristics including a reflectivity of 25% or more and 35% or less at a wavelength of 400 to 650 nm and a reflectivity of 60% or more at a wavelength of about 700 nm through optimization.
