Patent ID: 8350926

Claim:
An imaging apparatus comprising: an image pickup element for outputting an imaging result of an optical image formed on an imaging surface; an optical system for forming the optical image on the imaging surface; an analog-to-digital converting portion for converting the imaging result from analog to digital and outputting image data yet to be corrected; an image processing portion for subjecting the image data to an image correction processing and outputting the image data subjected to the image correction processing; a display portion for presenting an image of the image data subjected to the image correction processing; a pre-correction thumbnail-image-data generating portion for generating thumbnail image data yet to be corrected representative of a number of thumbnail images, by reducing resolution of the image data yet to be corrected in a vertical direction and a horizontal direction by use of a low-pass filter configured to perform a predetermined operation and thereafter by thinning the reduced resolution image data yet to be corrected in the vertical direction and in the horizontal direction; a corrected thumbnail-image-data generating portion for generating corrected thumbnail image data from the image data subjected to the image correction processing which is compressed in accordance with a JPEG (Joint Photographic Coding Experts Group) format; a data outputting portion for creating a file of the imaging result from the image data yet to be corrected, the thumbnail image data yet to be corrected, the corrected thumbnail image data and imaging information at the time of imaging-result capturing which includes at least image correction information which specifies the image correction processing by the image processing portion, and outputting the file, such that the outputted file has both the thumbnail image data yet to be corrected representative of the number of thumbnail images which were generated by thinning the image data yet to be corrected in the vertical direction and in the horizontal direction, and corrected thumbnail image data generated from the image data subjected to the image correction processing which is compressed in accordance with the JPEG format.
