Abstract
Abstract In order to prevent white compression from occurring in an image obtained by photography with a photography apparatus such as a digital camera, preliminary photography is carried out and actual photography is carried out while a flash control unit reduces an amount of light from a flash in the case where a predetermined target such as a human face is included in a preliminary image. Image processing is carried out on an actual image obtained through the actual photography for adjusting luminance and/or gradation of the predetermined target in the actual image.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
118 words
A photography apparatus comprising: photography means for obtaining an image representing a subject by photographing the subject, the photography means comprising imaging means for imaging the subject; illumination means for emitting an auxiliary light to the subject at the time of photography of the subject; processing control means for obtaining an actual image by carrying out actual photography of the subject with the photography means while reducing an amount of the auxiliary light in the case where a predetermined target has been detected in a preliminary image obtained by causing the photography means to carry out preliminary photography; and image processing means for adjusting luminance and/or gradation of a region of the predetermined target in the actual image.
Claim 2
Dependent Claim
118 words
A photography apparatus comprising: photography means for obtaining an image representing a subject by photographing the subject, the photography means comprising imaging means for imaging the subject; illumination means for emitting an auxiliary light to the subject at the time of photography of the subject; processing control means for obtaining an actual image by carrying out actual photography of the subject with the photography means while reducing an amount of the auxiliary light in the case where a predetermined target has been detected in a preliminary image obtained by causing the photography means to carry out preliminary photography; and image processing means for adjusting luminance and/or gradation of a region of the predetermined target in the actual image.
Claim 3
Dependent Claim
118 words
A photography apparatus comprising: photography means for obtaining an image representing a subject by photographing the subject, the photography means comprising imaging means for imaging the subject; illumination means for emitting an auxiliary light to the subject at the time of photography of the subject; processing control means for obtaining an actual image by carrying out actual photography of the subject with the photography means while lowering a gain of the imaging means in the case where a predetermined target has been detected in a preliminary image obtained by causing the photography means to carry out preliminary photography; and image processing means for adjusting luminance and/or gradation of a region of the predetermined target in the actual image.
Claim 4
Dependent Claim
118 words
A photography apparatus comprising: photography means for obtaining an image representing a subject by photographing the subject, the photography means comprising imaging means for imaging the subject; illumination means for emitting an auxiliary light to the subject at the time of photography of the subject; processing control means for obtaining an actual image by carrying out actual photography of the subject with the photography means while lowering a gain of the imaging means in the case where a predetermined target has been detected in a preliminary image obtained by causing the photography means to carry out preliminary photography; and image processing means for adjusting luminance and/or gradation of a region of the predetermined target in the actual image.
Claim 5
Dependent Claim
15 words
The photography apparatus according to claim 1 wherein the predetermined target is a human face.
Claim 6
Dependent Claim
15 words
The photography apparatus according to claim 2 wherein the predetermined target is a human face.
Claim 7
Dependent Claim
130 words
A photography method for a photography apparatus comprising: photography means for obtaining an image representing a subject by photographing the subject, the photography means comprising imaging means for imaging the subject; and illumination means for emitting an auxiliary light to the subject at the time of photography of the subject, the photography method comprising the steps of: detecting a predetermined target in a preliminary image obtained by causing the photography means to carry out preliminary photography; obtaining an actual image by carrying out actual photography of the subject with the photography means while reducing an amount of the auxiliary light in the case where the predetermined target has been detected in the preliminary image; and adjusting luminance and/or gradation of a region of the predetermined target in the actual image.
Claim 8
Dependent Claim
130 words
A photography method for a photography apparatus comprising: photography means for obtaining an image representing a subject by photographing the subject, the photography means comprising imaging means for imaging the subject; and illumination means for emitting an auxiliary light to the subject at the time of photography of the subject, the photography method comprising the steps of: detecting a predetermined target in a preliminary image obtained by causing the photography means to carry out preliminary photography; obtaining an actual image by carrying out actual photography of the subject with the photography means while reducing an amount of the auxiliary light in the case where the predetermined target has been detected in the preliminary image; and adjusting luminance and/or gradation of a region of the predetermined target in the actual image.
Claim 9
Dependent Claim
130 words
A photography method for a photography apparatus comprising: photography means for obtaining an image representing a subject by photographing the subject, the photography means comprising imaging means for imaging the subject; and illumination means for emitting an auxiliary light to the subject at the time of photography of the subject, the photography method comprising the steps of: detecting a predetermined target in a preliminary image obtained by causing the photography means to carry out preliminary photography; obtaining an actual image by carrying out actual photography of the subject with the photography means while lowering a gain of the imaging means in the case where the predetermined target has been detected in the preliminary image; and adjusting luminance and/or gradation of a region of the predetermined target in the actual image.
