Abstract
Abstract An image-capturing apparatus, includes: an image-capturing unit that captures an image of a subject through an optical system; and a control unit that outputs images captured at the image-capturing unit as image data files, and: the control unit outputs the image data files in a format that allows an image data file containing a normal image to be distinguished from an image data file containing a reference image to be used to correct an image defect in the normal image. An image processing apparatus, includes: an input unit to which an image data file output from the image-capturing apparatus is input; an identifying unit that identifies the image data file as a file containing the reference image or a file containing the normal image; and a correction unit that corrects an image defect in the image identified as the normal image based upon the image identified as the reference image.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
79 words
An image-capturing apparatus, comprising: an image-capturing unit that captures an image of a
subject through an optical system; and a control unit that outputs images captured at the
image-capturing unit as image data files, wherein: the control unit outputs the image data files in a format
that allows an image data file containing a normal image to
be distinguished froman image data file containing a reference
image to be used to correct an image defect in the normal image.
Claim 2
Dependent Claim
52 words
An image-capturing apparatus according to claim 1,
further comprising: a mode setting unit that sets a reference image
acquisitionmode in which the reference image is to be obtained,
wherein: the control unit designates an image captured by the
image-capturing unit when the reference image acquisition mode
is set as the reference image.
Claim 3
Dependent Claim
37 words
An image-capturing apparatus according to any one of
claims 1 through 2, wherein: the control unit appends different extensions to the
image data file containing the normal image and the image data
file containing the reference image.
Claim 4
Dependent Claim
73 words
An image-capturing apparatus according to any one of
claims 1 through 3, wherein: the image data files are each constituted of image data
corresponding to pixels in the image and information related
to the image; and the control unit stores information with which the image
data file containing the normal image and the image data file
containing the reference image can be distinguished from each
other in the information related to the image.
Claim 5
Dependent Claim
109 words
An image-capturing apparatus comprising: an image-capturing unit that captures a subject image
input through an optical system; a mode switching unit that selects a first mode in which
a reference image is captured by the image-capturing unit or
a second mode in which a normal image is captured by the
image-capturing unit; an output unit that outputs the reference image and the
normal image captured by the image-capturing unit as image
data files to an external apparatus; and an information appending unit that appends information
indicating whether an image data file output by the output
unit contains the reference image or the normal image to the
image data file.
Claim 6
Dependent Claim
50 words
An image-capturing apparatus according to claim 5,
wherein: the information appending unit appends metadata
containing information indicating either the reference image
or the normal image to the image data file; and the meta data do not alter the reference image or the
normal image contained in the image data file.
Claim 7
Dependent Claim
51 words
An image-capturing apparatus according to any one of
claims 5 through 6, wherein: the information appending unit appends the information
indicating whether the image data file contains the reference
image or the normal image to the image data file by partially
modifying a file name assigned to the image data file.
Claim 8
Dependent Claim
79 words
An image processing apparatus, comprising: an input unit to which an image data file output from
an image-capturing apparatus according to any one of claims
1 through 4 is input; an identifying unit that identifies the image data file
as a file containing the reference image or a file containing
the normal image; and a correction unit that corrects an image defect in the
image identified as the normal image based upon the image
identified as the reference image.
Claim 9
Dependent Claim
88 words
An image processing apparatus according to claim 8,
wherein: the image data files are each constituted of image data
corresponding to pixels in the image and information related
to the image; and the correction unit selects a specific reference image
to be used to correct an image defect in a given normal image
based upon the information related to the image contained in
the image data file of the reference image and the information
related to the image contained in the image data file of the
normal image.
Claim 10
Dependent Claim
87 words
An image processing apparatus, comprising: an input unit to which an image data file output from
an image-capturing apparatus according to any one of claims
5 through 7 is input; an identifying unit that identifies the image data file
as a file containing the reference image or a file containing
the normal image based upon the information; and an elimination unit that eliminates an effect of foreign
matter present on an image-capturing optical path at the
image-capturing unit from the normal image based upon the
reference image.
Claim 11
Dependent Claim
27 words
A computer-readable computer program product
comprising: a control program that executes a function of an image
processing apparatus according to any one of claims 8 through
10.
