  • Publication number: 20220337757
    Abstract: An imaging apparatus includes a processor, and an image sensor, in which a focus lens is moved while avoiding a period of main exposure by the image sensor in accordance with an instruction of the processor and the main exposure is continuously performed to perform continuous imaging at a predetermined time interval, and a processor calculates a first focus position of the focus lens with respect to a specific subject in a specific frame in which the main exposure is performed in a continuous imaging period, predicts a second focus position of the focus lens with respect to the specific subject in a frame ahead of the specific frame by a plurality of frames with reference to the first focus position in the continuous imaging period, and moves the focus lens toward the second focus position.

  • Publication number: 20220326479
    Abstract: An imaging apparatus is an imaging apparatus in which a focus lens is moved while avoiding a period of main exposure by an image sensor and the main exposure is continuously performed to perform continuous imaging, and a processor calculates a first focus position of the focus lens with respect to a specific subject based on image data obtained by imaging the specific subject with the main exposure by the image sensor in a specific frame in which the main exposure is performed in a continuous imaging period, predicts a second focus position of the focus lens with respect to the specific subject in a frame ahead of the specific frame by a plurality of frames with reference to the first focus position in the continuous imaging period, and moves the focus lens toward the second focus position.

  • Publication number: 20210337113
    Abstract: A system controller of a digital camera has a function of detecting a face region from a captured image which is output from an imaging element, and sets a face region detected from a first captured image, as a reference image, searches for a similar region similar to a specific image which is a part of the reference image from a second captured image output after the first captured image, and detects a first region including the similar region in the second captured image and having the same size as the reference image, as the face region. The position of the specific image in the reference image and the position of the similar region in the first region coincide with each other.

  • Patent number: 8988529
    Abstract: A detection area is decided in a case where a target has gone out-of-frame. If a target is being imaged by a camera continuously, it is determined whether the target has gone out-of-frame. If the target has gone out-of-frame, then the magnitude and direction of motion of the camera are detected. If camera motion is large, it can be concluded that the camera user is imaging the target while tracking it. Accordingly, it can be concluded that the target will again be imaged at the center of the imaging zone. An area defined as a region in which the target will be detected is set at the center of the imaging zone. If camera motion is small in a case where the target goes out-of-frame, it can be concluded that the user is waiting for the target to re-enter the imaging zone and therefore the edge of the imaging zone is set as the detection area.

  • Patent number: 8879794
    Abstract: An image obtained by imaging a subject is displayed and a tracking frame is displayed at the central portion of a display screen. A target area is set surrounding the tracking frame and a high-frequency-component image is generated. A distance image indicating the distance to the subject image within an imaging zone is generated. An area, which represents a subject at a distance identical with that of the subject portion specified by the tracking frame displayed at the reference position, is decided upon as a search area. While a moving frame is moved within the search area of the high-frequency-component image, amounts of high-frequency component are calculated. The position of the moving frame at which the calculated amount of high-frequency component is maximized is adopted as the initial position of the tracking frame.

  • Publication number: 20110187869
    Abstract: Automatic tracking of a target image is made comparatively easy. Specifically, an image obtained by imaging a subject is displayed on a display screen and a tracking frame is displayed at a reference position located at the central portion of the display screen. A target area for setting the initial position of the tracking frame is set surrounding the tracking frame and a high-frequency-component image representing high-frequency components of the image within this area is generated. The amount of high-frequency component is calculated while a moving frame is moved within the high-frequency-component image. The position of the moving frame where the calculated amount of high-frequency component is largest is decided upon as the initial position of the tracking frame.

  • Publication number: 20110080463
    Abstract: An image processing method executed in an apparatus, includes steps of: inputting a left-viewpoint image and a right-viewpoint image therebetween to the apparatus; searching for a corresponding point in the right-viewpoint image with respect to the left-viewpoint image, generating a first corresponding-point map based on a result of the searching, and generating a first intermediate-viewpoint image based on the left-viewpoint image; searching for a corresponding point in the left-viewpoint image with respect to the right-viewpoint image, generating a second corresponding-point map based on a result of the searching, and generating a second intermediate-viewpoint image based on the right-viewpoint image; extracting missing portions of pixels in the first and second intermediate-viewpoint images; determining whether a missing portion extracted is a missing portion to be interpolated or not; interpolating the missing portion to be interpolated based on a result of determination; and generating a third intermedia
