The focusing position detecting device includes contrast evaluation value calculating unit configured to calculate contrast evaluation values from a plurality of image data items obtained by imaging a subject a multiple number of times at a set exposure time while moving a focus lens in an optical axis direction within a search range, focusing position calculating unit configured to calculate a focusing position from focus positions at the time of imaging the subject a multiple number of times and the contrast evaluation values calculated by the contrast evaluation value calculating unit, detection unit configured to detect atmospheric fluctuation, and exposure time setting unit configured to set an exposure time in a case where the detection unit detects the atmospheric fluctuation so as to be longer than an exposure time in a case where the detection unit does not detect the atmospheric fluctuation.

Focusing position detecting device and focusing position detecting method

A subject is imaged repeatedly and color images of the subject are obtained. A color histogram is generated from the color subject image obtained and a representative color is decided from the color histogram generated. A specific color range that can be considered a color identical with the representative color is decided from the color histogram and representative color. Color outside the specific color range in the color subject image is changed to gray, an image of the subject in which the non-specific colors have been changed to gray is obtained and the image is displayed. Processing such as deciding the specific color range is repeated. When an instruction to fix the specific color is issued, the specific color range is fixed.

Image sensing apparatus and method of controlling operation of same

Disclosed are a focusing control device, an imaging device, a focusing control method, and a focusing control program capable of enabling focusing on an eye region and obtaining an intended focusing result. The focusing control device includes a focusing position determination unitwhich determines a focusing position based on a captured image signal obtained by imaging a subject with an imaging elementwhile moving a focus lens, and an AF region determination unitwhich determines an AF region based on a face region detected from a captured image signal obtained through imaging with the imaging elementat an arbitrary time and an eye region detected from a captured image signal obtained through imaging at a time before the arbitrary time. The focus lens is driven to the focusing position determined by the focusing position determination unitbased on a signal of the AF region.

The outlines of specific subjects becoming unnaturally deformed is prevented, while reducing the amount of calculations. A reference image setting section sets a reference image which is to become a reference from among a plurality of images. A specific subject detecting section detects a specific subject from within the reference image. A feature point extracting section extracts a plurality of feature points from within the reference image such that the average density of the feature points become higher in the vicinity of the outline of the specific subject. A corresponding point obtaining means corresponding point obtaining section obtains corresponding points within the other images that correspond to the extracted feature points. A coordinate converting section converts the coordinates of the positions of each pixel within the reference image and/or the other images such that the positions of the feature points and the positions of the corresponding points match.

Image processing apparatus, image processing method, and image processing program

An imaging apparatus displays and records any area in a synthesized image according to user's taste. The synthesized image is displayed based on the set display area and the record area is set to display the synthesized image, so that the display area is compared with the record area to enable easily confirming whether the actually acquired synthesized image satisfies the area desired by the user and assisting recording in an area where a better composition is provided even if the user is unfamiliar with the composition.

Imaging apparatus, method and program

An image processing apparatus that an image input unit; a parallax acquisition unit configured to acquire a per-pixel or per-region parallax between two-viewpoint images; a main subject detection unit configured to detect a main subject on the two-viewpoint images; a parallax acquisition unit configured to acquire a parallax of the main subject; a setting unit configured to set a conversion factor of the parallax; a correction unit configured to correct the conversion factor of the parallax per pixel, per region, or per image; a multi-viewpoint image generation unit configured to convert at least one image of the two-viewpoint images in accordance with the corrected conversion factor of the parallax; an image adjustment unit configured to shift the two-viewpoint images or multi-viewpoint images to obtain a parallax appropriate for stereoscopic view; and a stereoscopically-displayed image generation unit configured to generate a stereoscopically-displayed image.

Image processing apparatus and image processing method

A plurality of images are obtained in photography according to a plurality of photography methods, and photography result scores are calculated for the respective images. Judgment is made as to whether a highest score among the scores calculated for the respective images is equal to or larger than a predetermined threshold value. If a result of the judgment is affirmative, the image having the highest score is recorded in a recording medium. If the result of the judgment is negative, the images are displayed on display means to receive selection of a desired one of the images. The selected image is recorded in the recording medium.

Apparatus, method and program for photography

Both a specific target and the background thereof in the image of a subject are caused to take on brightnesses that are relatively appropriate. Preliminary image sensing is performed to obtain a preliminary image of the subject. The image of a face is detected from within the preliminary image of the subject and the representative luminance of the face image is calculated. If the representative luminance calculated is not appropriate, then amount of exposure is adjusted so as to make the face image slightly darker than the appropriate brightness. Regular image sensing is then carried out. If the representative luminance of the face image in the image of the subject obtained by regular image sensing is not appropriate, a tone adjustment is applied utilizing a tone curve. Thus there is obtained an image of the subject in which both the face image and its background exhibit brightnesses that are relatively appropriate.
