A positive electrode active material for a nonaqueous electrolyte secondary battery includes a positive electrode active material particle and a compound containing a rare earth element and a carbonate, the compound having a particle size of 1 to 100 nm and being adhered to a surface of the positive electrode active material particle. The high dynamic range image can be reconstructed from the tone map and the HDR information. When molding the kneaded material, it is heated to the temperature at which the skin starts to melt and pressed. The lens structure includes a first surface, a second surface opposite to the first surface and four total internal reflection surfaces connected to the second surface.
