An imaging device, comprising a dark image data imaging section for acquiring first dark image data acquired by shooting in a state where a light beam incident on the imaging surface of the image sensor is shielded, before acquiring first image data that has been read out from the image sensor, and second dark image data acquired by shooting in a state where a light beam incident on the imaging surface of the image sensor is shielded after the second image data that was finally acquired, a corrected image data generating section for generating dark corrected image data by carrying out combination processing based on a comparison result of comparing the first and second dark image data, or an averaging computation result, and a correction section for correcting fixed pattern noise within the cumulatively combined image data using the dark corrected image data. |

1. An imaging device, that stores first image data that has been initially generated based on image data that has been read out from an image sensor as cumulatively combined image data in a first memory, followed by sequentially repeating operations of an image processing section carrying out combination processing to reconstruct the cumulatively combined image data pixel data by making pixel data, that is based on a comparison result of comparing a plurality of pixel data constituting second image data that has been generated based on image data that has been read out from the image sensor with pixel data respectively corresponding to a plurality of pixel data constituting the cumulatively combined image data, and/or an averaging computation result, new pixel data, and the first memory storing the cumulatively combined image data after the reconstruction for the second image data of second and subsequent frames that have been generated based on image data that has been read out from the image sensor, comprising:
a shutter that is put into an exposed state or a light shielding state of blocking or passing a light beam that is incident on an imaging surface of the image sensor, a controller including an image sensor control section, a shutter control section, and dark image data imaging section, (1) the image sensor control section for carrying out control to cause operation to read out image data from the image sensor, (2) the shutter control section for controlling to cause operation to place the shutter in an exposing state or a light shielding state, (3) the dark image data imaging section for acquiring first dark image data before acquiring the first image data by placing the shutter in a light shielding state for a light beam that is incident on the imaging surface of the image sensor, and causing a shooting operation of the image sensor in the light shielding state, and second dark image data by, after the second image data that has been finally acquired, placing the shutter in a light shielding state for the light beam that is incident on the imaging surface of the image sensor, and causing a shooting operation of the image sensor in the light shielding state, a corrected image data generating section for generating dark corrected image data by carrying out combination processing based on a comparison result of comparing the first and second dark image data, or an averaging computation result, and a correction section for correcting fixed pattern noise within the cumulatively combined image data using the dark corrected image data. |
