摘要： PROBLEM TO BE SOLVED: To make each of a plurality of main objects 32 and 33 comparatively proper brightness when the plurality of the main objects exist.
SOLUTION: The main object 32 is detected from among the objects existing in a photographing range 30. Automatic focusing control processing is performed so that a focus is on the main object 32. When the main object 34 exists as well as the main object 32, automatic exposure control processing is performed so that both of the objects 32 and 34 have proper brightness. Even when the plurality of the main objects exist in the photographing range, object images expressing any main object have comparatively proper brightness.

摘要： PROBLEM TO BE SOLVED: To comparatively easily select an image to be printed among many frame images.
SOLUTION: When an object is photographed, an object image 20B is previewed on a display screen 20. A user is allowed to look at the previewed object image 20B to judge whether to be a print candidate. When the object image 20B is judged to be a print candidate, an image file is stored in a print candidate folder. When an image to be a print object is selected, the image is selected among images represented by the image file stored in the print candidate folder. Since the number of frames of images to be a selection object is reduced, images to be printed can be comparatively easily selected.

摘要： PROBLEM TO BE SOLVED: To provide an imaging apparatus by which all object people are photographed to be directed in the imaging apparatus by utilizing a function of detecting eyes of people in the photographing using a self-timer so that.
SOLUTION: The number of object people is registered in a section for registering the number of object people before self-timer photographing. A self timer time management section 38 sets an eye detection start time. An electronic shutter is activated when an eye detection processing section 36 detects eyes whose number agree with the registered number of the object people after the operation of the self timer is started and after the eye detection start time elapses. Since the detection of the eyes equivalent to the number of object people by the eye detection processing section 36 indicates that the faces of the entire object people faces a digital camera 10, a preferable portrait is photographed.

摘要： PROBLEM TO BE SOLVED: To provide an imaging apparatus capable of obtaining a preferable image in a state of a backlight scene or a high contrast scene. SOLUTION: The digital camera extracts a region equivalent to that of the face of a person in the case of exposure correction and provides assist information on the basis of information obtained from the extracted face region. A photographer can judge the propriety of exposure correction and a correction amount on the basis of the assist information, and obtain an excellent image wherein a principal object is reproduced with proper lightness and colors with less image deterioration such as black decay in the backlight scene, white jump and yellowing in the high contrast scene. The photographer can easily judge occurrence of the black decay and white jump or the like by the assist information for indicating a histogram of a hue of the face region. On the occurrence of yellowing, the digital camera raises warning, then production of a deteriorated image in spite of carrying-out of the exposure correction or deterioration in the reproduced image due to too much correction can be avoided.

摘要： PROBLEM TO BE SOLVED: To provide a method and device capable of accurately extracting a face area when the in exposure is changing by backlight or in excessive light. SOLUTION: A plurality times of photometries are conducted on several conditions to precisely measure a wide dynamic range in an AE processing of a digital camera (steps S110 to S112). An image having a highest chroma of the complexion area out of a plurality of images captured by a plurality times of photometries is selected (step S118). An area having a hue of the complexion within the image in that image is detected (step S120), and an obtained complexion area is divided by chroma (S122). Each complexion area divided by chroma is shape recognized (step S124), and a final face area is extracted. In place of the use of the photometries, information on a bracket photographing for serially photographing the same scene by different exposure conditions (correct, under, or over exposure) may be used.

摘要： PROBLEM TO BE SOLVED: To provide a calibrating device for an imaging device which is easily applicable to a general commercial electronic camera, a portable telephone with a camera, etc., and corrects influences caused by variations in an image output characteristic and the temporal change of an imaging element. SOLUTION: A portable telephone 2 has an imaging part 22 and a character/image information display part 16. Images for calibration to be a standard of prescribed colors are stored in an image memory 6 for calibration. When the imaging part 22 is placed close to the character/image information display part 16 for displaying an image for calibration, a displayed image for calibration is picked up by the imaging part 22 and the picked-up image is displayed on the character/image information display part 16, a control part 8 gives a variable coefficient or function to an image generation process so as to display the picked up image for calibration on the character/image information display part 16 in a desired color.

摘要： PROBLEM TO BE SOLVED: To provide an image correction processing apparatus and program for reducing an image data capacity to a limit capacity being a distribution available data capacity or below without deteriorating the image quality of the face of a portrait in the case of distributing a portrait image. SOLUTION: A YC conversion / simultaneous processing section 206 applies YC conversion to image data of the portrait image and thereafter a face extract processing section 208 extracts a face image area to separate the converted image into the face image area and a non-face image area other than the face. A sharpness parameter decision section 209 decides parameters to weaken the sharpness of the non-face image area more than that of the face image area, and an area dependent sharpness processing section 210 individually applies sharpness processing to each of the face image area and the non-face image area. Thus, the image data wherein the data capacity of the areas other than the face is properly reduced is obtained in a way that the data capacity after image compression by a JPEG compression section 212 is within a distribution capacity limit.

SOLUTION: An imaging apparatus for imaging an image with a wide dynamic range by adding and combining an image signal with a low sensitivity signal and an image signal with a high sensitivity signal includes a first gamma correction means 13a for performing gamma transformation of the image signal with the high sensitivity signal by a first gamma characteristic, a second gamma correction means 13b for performing the gamma transformation of the image signal with the low sensitivity signal by a second gamma characteristic different from the first gamma characteristic, and an adder means 14 for adding an image signal output from the correction means 13a and an image signal output from a second gamma correction means 13b to output it. Therefore, it becomes possible to create and output the image with normal feeling in a wide dynamic range. COPYRIGHT: (C)2004,JPO
