摘要： Dual-aperture digital cameras with auto-focus (AF) and related methods for obtaining a focused and, optionally optically stabilized color image of an object or scene. A dual-aperture camera includes a first sub-camera having a first optics bloc and a color image sensor for providing a color image, a second sub-camera having a second optics bloc and a clear image sensor for providing a luminance image, the first and second sub-cameras having substantially the same field of view, an AF mechanism coupled mechanically at least to the first optics bloc, and a camera controller coupled to the AF mechanism and to the two image sensors and configured to control the AF mechanism, to calculate a scaling difference and a sharpness difference between the color and luminance images, the scaling and sharpness differences being due to the AF mechanism, and to process the color and luminance images into a fused color image using the calculated differences.

摘要： 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.

摘要： A lens barrel of the invention includes: an imaging optical system including a focus adjustment lens; a driver that drives the focus adjustment lens in a direction of an optical axis; a transceiver that transmits and receives a signal to and from a camera body; and a controller that controls the transceiver to repeatedly transmit a first image plane transfer coefficient which is determined in correspondence with a position of the focus adjustment lens included in the imaging optical system and a second image plane transfer coefficient which does not depend on the position of the focus adjustment lens to the camera body at a predetermined interval, and, when the controller repeatedly transmits the second image plane transfer coefficient to the camera body, the controller varies the second image plane transfer coefficient over time.

摘要： An image capturing device includes a lens, a lens driver configured to change a focus position by moving the lens, an image sensor configured to detect light passed through the lens, and a focus controller configured to control, based on an image generated by the image sensor, the lens driver to adjust the focus position. The focus controller is further configured to: monitor a feature change of a saturated object having an intensity greater than or equal to a threshold value, in each of a plurality of regions of an image, by adjusting the focus position; and adjust the focus position based on a trend of the feature change of the saturated object while the focus position is changed in a direction.

摘要： An imaging apparatus includes: an imaging sensor; a lens mount to which a lens is attached; and a processor is configured to read out an imaging signal from the imaging sensor and generate a raw image. The processor is configured to determine a length of a second focal length in a second direction which intersects with an extending direction of an optical axis of the lens and a first direction which intersects with the extending direction, relative to a first focal length in the first direction, and make a resolution ratio, which is a ratio of a resolution of the raw image in the first direction to a resolution of the raw image in the second direction, higher than a resolution ratio of the imaging sensor in a case where the second focal length is longer than the first focal length.

摘要： An imaging device and a focusing control method are provided. The imaging device includes: an imaging element, having pixels including phase-difference detecting pixels and imaging a subject through an imaging optical system including a focus lens; and a focusing controller, selectively performing focusing control using a phase difference AF method or focusing control using a contrast AF method in a mode in which focusing control for focusing on a main subject by driving the focus lens is continuously performed multiple times. The focusing controller performs the focusing control using the contrast AF method in a case where a state in which a degree of reliability of the focusing control using the phase difference AF method is equal to or less than a threshold value persists N times (N=2 or more), while the focusing control using the phase difference AF method is continuously performed.

摘要： Provided is an imaging apparatus and an imaging method that sets a type of a subject as a focusing target in each imaging. The imaging apparatus includes an image sensor that acquires an image, and an operation unit that selects a type of the subject as the focusing target in each imaging of the image acquired by the image sensor. In the case where the type of the subject as the focusing target is selected by the operation unit, a microcomputer detects an area of the subject of that type from the image and sets the detected area as an in-focus area of the image.
