Abstract
An imaging device includes a modulator, a first grating pattern constituted by a plurality of lines, and a second grating pattern having a phase deviating from a phase of the first grating pattern, and modulates light intensity. The imaging device receives a first image signal output by the first grating pattern and a second image signal output by the second grating pattern, calculates difference data and a range of a difference between the first image signal and the second image signal, generates and sets a data conversion parameter at a regular interval from the difference data that is continuously input on the basis of the range of the difference and the difference data, generates compression image data by using the difference data and the data conversion parameter, compresses the generated compression image data, and includes information indicating the range of the difference into the compressed data.
