Patent Images

1. An imaging device for taking an image of an object, said imaging device comprising:

  • a lens array including a plurality of lenses;

    an imaging element provided at a predetermined distance from said lens array and having a plurality of imaging areas respectively corresponding to said plurality of lenses;

    a light-shielding wall which partitions a space between said lens array and said imaging element so as to prevent light entering each of said plurality of lenses from reaching said plurality of imaging areas different from a corresponding one of said plurality of imaging areas;

    an imaging signal input unit configured to generate an imaging signal by digitalizing an electric signal provided by said imaging element; and

    a temperature estimation unit configured to calculate, from the imaging signal, a length of an image of said light-shielding wall projected on an imaging plane of said imaging element, and to estimate a first temperature using the calculated length of the image of said light-shielding wall.
