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.

The present invention provides an imaging device and a focusing control method capable of enhancing accuracy of moving subject estimation while reducing the computation of the moving subject estimation used in a case of continuously performing focusing with respect to the moving subject. A system control unit () predicts a subject distance in an imaging process of a third frame from information about subject distances obtained in an imaging process of a first frame and an imaging process of a second frame, calculates an error with respect to the predicted subject distance from information about a maximum error with respect to a focus lens position to be calculated, and performs lens driving based on a predicted focus lens position instead of a focusing control based on the predicted subject distance in a case that the error of the subject distance is large.

Imaging device and focusing control method

An image for a left eye and an image for a right eye are respectively captured. A corresponding point corresponding to each of a plurality of feature points detected from the image for a left eye is searched for using the image for a right eye. The number of corresponding points found by the search is counted, and it is determined whether to be equal to or more than a predetermined ratio with respect to the number of pixels of the image for a right eye. When the number of corresponding points is determined to be less than the predetermined ratio, the image for a right eye is recaptured, and the corresponding point search process and the determination of whether the number of corresponding points is equal to or more than the predetermined ratio are re-executed using an image new for a right eye obtained by recapture.

Imaging apparatus and method of driving solid-state imaging device

The presence/absence of a face in an image and the type of imaging mode during imaging (such as a landscape imaging mode and a close-up imaging mode) of the image acquired by imaging and the like are detected. Images are automatically classified by groups based on the detected information (classification information). A plurality of images classified by the groups are connected to create a multi-image file (MP file), and the MP file is recorded in a recording medium. As a result, the plurality of classified images can be managed altogether (without dissipation), and the plurality of classified images can be reproduced by providing the multi-image file even if a reproducer does not have a classification function.

Two kinds of color images, obtained by a solid-state imaging device, having different color tones are combined with each other. A first captured color image due to a first pixel group (pixels in which spectral sensitivities of color filters are wide) of the solid-state imaging device is processed. A second captured color image due to a second pixel group (pixels in which spectral sensitivities of color filters are narrow) is processed. The level difference between captured image signals of the pixels of the first pixel group and captured image signals of the pixels of the second pixel group, and due to the spectral sensitivity difference between the color filters in which the spectral sensitivities are wide and narrow is obtained (steps Sand S). The level difference is corrected. The first captured color image and the second captured color image are combined with each other.

Imaging apparatus, method of processing captured image, and program for processing captured image

A color that readily leaves an impression is adopted as the representative color of a color image. Pixels that form a color image are distributed in L*a*b* color space and are projected onto the a*b* plane. The pixels are grouped and the color at the centroid position of each group is adopted as a representative candidate color. A first score is calculated based upon the distance from the origin, which is indicative of gray, to the representative candidate color, and a second score is calculated from the number of pixels contained in the group. A final score is calculated from the first and second scores and representative candidate colors that provide the three highest final scores are decided upon as representative colors.
