Provided are an imaging apparatus and an imaging method capable of relatively accurately focusing on a main object in a relatively short time. A movement region () of a main object OA is imaged in a camera apparatus A and a different camera apparatus B. In the camera apparatus A, the main object OA is recognized from a captured image. Data indicating the position of the main object OA, transmitted from the camera apparatus B, is received in the camera apparatus A, and a focusing target range is set at the front and back of the position of the main object OA. A movement of a focus lens of the camera apparatus A is limited so as to focus on the focusing target range.

Imaging apparatus and imaging method

The focusing control device capable of preventing deterioration in precision of focusing control from being caused by an error in phase-difference depending on ambient temperature includes: an imaging element that outputs a pair of image signals deviated in one direction on the basis of one subject light image; a phase-difference detection section that detects a phase-difference between the pair of image signals; a temperature detection section; a correction section that corrects the in-focus position of the focus lens based on the detection phase-difference, which is the phase-difference detected by the phase-difference detection section, on the basis of the data in which the temperature, the focus lens position, and the information for in-focus position correction are associated with one another, the temperature which is detected by the temperature detection section, and the focus lens position; and a lens control section that moves the focus lens to the corrected in-focus position.

Focusing control device, lens device, imaging apparatus, focusing control method, and focusing control program

A digital camera is provided with a frequency component extraction unit, an AR evaluation value acquisition unit, a variation calculation unit, and a moving speed control unit. The frequency component extraction unit has first and second filters, and extracts first and second spatial frequency components. The AF evaluation value acquisition unit integrates the first and second spatial frequency components to acquire first and second AF evaluation values. The variation calculation unit calculates a first variation corresponding to first-order differentiation of the first AF evaluation value, a second variation corresponding to first-order differentiation of the second AF evaluation value, and a third variation corresponding to second-order differentiation of the second AF evaluation value. The moving speed control unit controls the moving speed of a focus lens at the time of an AF operation based on the rates of increase or decrease of the first to third variations.

Photographic apparatus and method for focusing control using two high pass filters

An imaging method includes setting a manual focus mode for moving a focus lens according to an operation of an operation unit, generating a contrast image, which is an image in which an edge of a taken image is enhanced or extracted, and superimposing and displaying, in the case of the manual focus mode, the contrast image on an optical image of the object in an optical finder.

Imaging device, imaging method and recording medium

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.
