There is provided a focus prediction apparatus. A detection unit detects two or more subjects in each of a plurality of images that are sequentially generated through continuous shooting. A selection unit selects a main subject from among the two or more subjects with respect to each of the images. With respect to each of the images, a storage unit stores a focus position at which a target subject is brought into focus, for each of the two or more subjects as the target subject. A prediction unit performs first prediction processing in response to generation of a first image through the continuous shooting, the first prediction processing being for predicting a future focus position of a main subject in the first image based on a history of focus positions corresponding to the main subject in the first image.

Focus prediction apparatus, image capturing apparatus, focus prediction method, and storage medium

An image capturing apparatus includes an object detection unit configured to detect an object, a posture detection unit configured to detect a posture of the object, a focus detection unit configured to detect a focusing state of the object; and a setting unit configured to set a threshold value for determining whether or not to select the object as a main object based on a posture and the focusing state of the object.

Image capturing apparatus capable of selecting an object to be focused, control method thereof, and storage medium

An apparatus configured to perform focus tracking on an object within a detection area to detect a defocus amount within an imaging angle of view includes a memory storing instructions, and a processor configured to execute the instructions to perform focus tracking determination to determine whether or not the focus tracking is to be performed using information about the defocus amount, and acquire information about a shield against the object from image data generated by imaging. The processor is configured to perform the focus tracking determination using information about the shield acquired in the detection area.

Focus control apparatus, image pickup apparatus, and focus control method

There is provided an inference apparatus. An inference unit performs inference with use of a machine learning model based on a subject region including a subject within an image obtained through shooting, and on a plurality of distance information pieces detected from a plurality of focus detection regions inside the subject region, thereby generating an inference result indicating a distance information piece corresponding to the subject or a distance information range corresponding to the subject. The machine learning model is a model that has been trained to suppress a contribution made to the inference result by one or more distance information pieces that are not based on the subject among the plurality of distance information pieces.

Inference apparatus, image capturing apparatus, training apparatus, inference method, training method, and storage medium

A focusing apparatus includes a determination unit configured to determine whether an object is a moving object, and a focusing unit configured to perform focusing using information on driving of the focus lens generated based on the focus detecting signal in response to an operation of an operation unit. The determination unit determines whether the object is the moving object, using a first threshold before the operation of the operation unit, and using a second threshold different from the first threshold after the operation of the operation unit. The focusing unit performs first focusing that continuously performs the focusing when the determination unit determines that the object is the moving object before the operation of the operation unit, and performs the first focusing when the determination unit determines that the object is the moving object after performing second focusing that performs the focusing once.

Focusing apparatus, image pickup apparatus, focusing method, and storage medium, which can provide stable focusing

An apparatus includes a calculation unit that calculates a plurality of defocus amounts corresponding to a plurality of focus detecting frames obtained by dividing an area corresponding to a display frame, and a selection unit that selects one focus detecting frame which corresponds to one defocus amount used for an AF control. The selection unit changes an AF operation for selecting the one focus detecting frame based on the number of low contrast frames to the number of focus detecting frames or based on reliability selected from part of the area and a ratio of focus detecting frames having a high reliability in the area, or performs an AF operation for selecting the one focus detecting frame so that a high contrast frame is prioritized over a low contrast frame.

Control apparatus, image pickup apparatus which changes an autofocus operation based on a ratio of a number of low contrast frames to a number of focus detecting frames

A control apparatus () includes a calculator () that calculates a defocus amount based on a first signal and a second signal that correspond to light beams passing through different pupil regions of an image capturing optical system () from each other, and a focus adjuster () that performs focus adjusting operation based on the defocus amount, and the focus adjuster is configured to change a detection property of the first signal and the second signal depending on a type of the focus adjusting operation.
