An imaging apparatus includes: an image sensor that captures a subject image to generate image data; a first depth measurer that acquires first depth information indicating a depth at a first spatial resolution, the depth showing a distance between the imaging apparatus and a subject in an image indicated by the image data; a second depth measurer that acquires second depth information indicating the depth in the image at a second spatial resolution different from the first spatial resolution; and a controller that acquires third depth information indicating the depth at the first or second spatial resolution for each region of different regions in the image, based on the first depth information and the second depth information.

The present disclosure provides systems, apparatus, methods, and computer-readable media that support multi-frame depth-of-field (MF-DOF) for deblurring background regions of interest (ROIs), such as background faces, that may be blurred due to a large aperture size or other characteristics of the camera used to capture the image frame. The processing may include the use of two image frames obtained at two different focus points corresponding to the multiple ROIs in the image frame. The corrected image frame may be determined by deblurring one or more ROIs of the first image frame using an AI-based model and/or local gradient information. The MF-DOF may allow selectively increasing a depth-of-field (DOF) of an image to provide focused capture of multiple regions of interest, without causing a reduction in aperture (and subsequently an amount of light available for photography) or background blur that may be desired for photography.

An image sensing device includes an image sensor suitable for correcting depth information based on a control signal, and for generating image data according to the depth information, and a controller suitable for analyzing an error of the depth information, and for generating the control signal, based on first and second cycle signals provided from the image sensor.

An apparatus includes an acquisition unit configured to acquire distance information that indicates a distance to a subject on each predetermined region in a captured image, a control unit configured to adjust a focus position, and a storage unit configured to store first distance information acquired by the acquisition unit in response to the adjusted focus position. The control unit readjusts the focus position based on the first distance information and second distance information acquired by the acquisition unit.

A control apparatus includes a first acquiring unit configured to acquire a hyperfocal length of a lens apparatus that is attachable to, detachable from, and communicable with an image pickup apparatus, using information acquired by communication between the lens apparatus and the image pickup apparatus, and a second acquiring unit configured to acquire a position of a focus lens in the lens apparatus according to the hyperfocal length.

A control apparatus includes a first acquiring unit configured to acquire a hyperfocal length of a lens apparatus that is attachable to, detachable from, and communicable with an image pickup apparatus, using information acquired by communication between the lens apparatus and the image pickup apparatus, and a second acquiring unit configured to acquire a position of a focus lens in the lens apparatus according to the hyperfocal length.

A control apparatus includes a first control unit configured to automatically adjust a focus lens to an in-focus position, and a second control unit configured to adjust the focus lens based on an operation amount of a user. The first control unit and the second control unit are enabled in a first driving area of the focus lens. The first control unit is disenabled in a second driving area of the focus lens. While the first control unit adjusts the focus lens to the in-focus position, the second control unit is disenabled in the second driving area.

An image processing apparatus includes an acquisition unit configured to acquire an image captured by an imaging unit, and image capturing information at the time of image capturing of the image, and a calculation unit configured to calculate an object side pixel dimension of a target subject in the image based on the image capturing information and a pixel dimension of the imaging unit, wherein the acquisition unit acquires in-focus information indicating an in-focus state of a subject in an image, as the image capturing information, and wherein the calculation unit calculates the object side pixel dimension based on the in-focus information.

A camera (10) is provided for the detection of objects (48) moved through a detection zone that has an image sensor (18) for recording image data, a reception optics (16) having an adjustable diaphragm (17), and a control and evaluation unit (38) to read the image data and to set the diaphragm (17), In this respect, the control and evaluation unit (38) is furthermore configured to set the diaphragm (17) per object (48) such that the object (48) is recorded in a depth of field range.

Systems, methods, and computer-readable media are provided for low power, variable focus. An example method can include obtaining, based on a trigger, a first image of a scene captured by an image sensor, the first image being captured with a lens of the image sensor in a first configuration of a plurality of available lens configurations; determining, based on the first image and a first detection result, whether an object of interest is present in the first image; in response to determining that the object of interest is not present in the first image, adjusting the lens to a second configuration selected from the plurality of lens configurations; obtaining, by the image sensor, a second image of the scene while the lens is in the second configuration; and determining, based on the second image and a second detection result, that the object of interest is present in the second image.
