A focusing control device includes: an evaluation value calculation unit that causes an imaging element which images a subject through a focus lens to image the subject for each of positions of the focus lens while moving the focus lens movable in an optical axis direction, and calculates evaluation values for determining a focusing position of the focus lens based on signals acquired by performing any filtering process selected among a plurality of filtering processes in which passbands are different on captured image signals acquired through the imaging; a focusing position determination unit as defined herein; and a focusing control unit that performs focusing control to move the focus lens to the focusing position, and the focusing position determination unit increases number of the selected evaluation values as a lower frequency limit of the passband becomes lower, as the filtering process selected by the evaluation value calculation unit.

The present disclosure includes an imaging control apparatus, an imaging control method, and an imaging apparatus. The imaging control apparatus includes a focal point detection control circuitry configured to receive first information from a range-finding area of a dedicated phase difference detection sensor and second information from a range-finding area of an image plane phase difference detection sensor, and detect a focal point based on at least one of the first information or the second information.

An adjusting method of a camera module, a lens position control device, a control device of a linear movement device, and a controlling method of the same are provided in a state of the cameral module in which an imaging element and an actuator are combined. The camera module includes a position sensor (53) that detects a position of a lens (50) to output a detection position signal, a storage unit (541) that stores and rewrites a position code value corresponding to the position of the lens, a target position signal generation unit (542) that outputs a target position signal based on the position code value and the target position code value, and a control unit (543) that generates a control signal based on the target position signal and the detection position signal.

A method for removing air micro-bubbles from photoresist used to purge a new photoresist filter is disclosed. The method includes flowing photoresist through a photoresist filter to remove air trapped in the photoresist filter, where the trapped air forms air micro-bubbles in the photoresist; collecting, in a buffer tank, the photoresist with air micro-bubbles; removing, in the buffer tank, the air micro-bubbles from the photoresist; and transferring the photoresist without air micro-bubbles from the buffer tank to photolithography equipment.

A method of detecting a change in angular position of a camera. A plurality of frames captured by the camera is received, each frame being associated with brightness and acceleration metadata. The brightness metadata is associated with a frame being representative of brightness of a scene captured by the frame. A contiguous set of candidate panning motion frames is selected from the plurality of frames, based on similarity of acceleration characteristics, to determine a change of brightness metadata in the selected contiguous set of frames. An angular movement score is determined for the selected contiguous set of frames using the change of brightness metadata. A change in the angular position of the camera is detected based on the angular movement score to adjust a manner in which the plurality of frames is displayed by a display device coupled with the camera.

The present disclosure includes an imaging control device, an imaging control method, and an imaging apparatus. The imaging control device includes a focus detection control circuitry configured to determine whether a setting area includes a portion of a dedicated phase difference detection sensor, the setting area being in a photographing range of an imaging unit. The focus detection control circuitry is further configured to set one or more ranging areas of an image plane phase difference detection sensor to one or more first ranging areas in response to determining that the setting area does not include the portion of the dedicated phase difference detection sensor.

An operation method of a multiple lenses system applied in an electronic device is provided. The multiple lenses system includes at least one first lens and at least one second lens. The operation method includes: selecting a present capturing mode from a plurality of capturing modes; obtaining a preview image; estimating a focus distance by obtaining a sharpness of an object's edge in the preview image; determining whether the focus distance crosses a threshold; and switching from the at least one first lens to the at least one second lens or switching from the at least one second lens to the at least one first lens to obtain the preview image if the focus distance crosses the threshold. An electronic device is also provided.

A focusing control device includes: an evaluation value calculation unit that causes an imaging element which images a subject through a focus lens to image the subject for each of positions of the focus lens while moving the focus lens movable in an optical axis direction, and calculates evaluation values for determining a focusing position of the focus lens based on signals acquired by performing any filtering process selected among a plurality of filtering processes in which passbands are different on captured image signals acquired through the imaging; a focusing position determination unit as defined herein; and a focusing control unit that performs focusing control to move the focus lens to the focusing position, and the focusing position determination unit increases number of the selected evaluation values as a lower frequency limit of the passband becomes lower, as the filtering process selected by the evaluation value calculation unit.
