Abstract
The number of thermal sensors in an imaging device that requires temperature measurement is reduced. The imaging device includes: a lens array () including lenses; an imaging element () provided at a predetermined distance from the lens array () and having imaging areas respectively corresponding to the lenses; a light-shielding wall () which partitions a space between the lens array and the imaging element so as to prevent light entering each of the lenses from reaching the imaging areas different from a corresponding one of the imaging areas; an imaging signal input unit () configured to generate an imaging signal by digitalizing an electric signal provided by the imaging element; and a temperature estimation unit () configured to calculate, from the imaging signal, a length of an image of the light-shielding wall projected on an imaging plane of the imaging element, and to estimate a temperature using the calculated length of the image of the light-shielding wall.
