IMAGING APPARATUS AND IMAGING METHOD

摘要

An imaging apparatus comprising: a dark image data imaging section that obtains dark image data in a state in which light beams entering an imaging surface of an image sensor are shielded before first image data is obtained or after second image data obtained lastly; and a correcting section that corrects a fixed pattern noise in cumulative relatively bright composite image data by using the dark image data, wherein the correcting section corrects the fixed pattern noise in the cumulative relatively bright composite image data by using the dark image data obtained at a time closest to the time in a temperature of the image sensor when the first image data or the second image data is obtained is assumed to be the highest, of the dark image data obtained before the first image data is obtained or the dark image data obtained after the second image data obtained lastly.

1. An imaging apparatus that repeatedly and sequentially performs relatively bright composition processing on second image data in a second frame and after generated on the basis of image data read out of an image sensor, the relatively bright composition processing storing first image data generated first on the basis of the image data read out of the image sensor as cumulative relatively bright composite image data, comparing respective corresponding pixel data of a plurality of pieces of pixel data constituting the second image data generated on the basis of the image data read out of the image sensor and of a plurality of pieces of pixel data constituting the cumulative relatively bright composite image data, and reconstructing the cumulative relatively bright composite image data using the larger pixel data as new pixel data, the imaging apparatus comprising:
a dark image data imaging section that obtains dark image data in a state in which light beams entering an imaging surface of the image sensor are shielded before the first image data is obtained or after the second image data obtained lastly; and a correcting section that corrects a fixed pattern noise in the cumulative relatively bright composite image data by using the dark image data, wherein the correcting section corrects the fixed pattern noise in the cumulative relatively bright composite image data by using dark image data obtained at a time closest to the time in a temperature of the image sensor when the first image data or the second image data is obtained is assumed to be the highest, of the dark image data obtained before the first image data is obtained or the dark image data obtained after the second image data obtained lastly.
