An image obtained on imaging is correlated with the information pertinent to a privacy mask, designed to shield an image obtained on imaging, for convenience in image recording processing by an external device, including a downstream side image recording device, first and foremost. Micro proppant of 200 mesh or smaller is pumped into far field fractures of the subterranean zone and props the far field fractures open. The resin-molded layer is formed by introducing the material into the space formed between the one surface of the base member and a transfer surface formed on a transfer die correspondingly to the surface of a lens to be produced to be cured by heat or ultraviolet rays. A control circuit is operatively connected to the MEMS.
