Abstract: An imaging apparatus in the present disclosure includes an imaging unit for capturing an object image and generating image data, a focus lens for focusing the object image onto the imaging unit, an operation unit for receiving an instruction of a user, and a controller. The operation unit can set a first focus point and a second focus point that is different from the first focus point. The controller obtains information on a first focus position that is a position of the focus lens to focus on an object image at the first focus point and a second focus position that is a position of the focus lens to focus on an object image at the second focus point, before receiving from a user an instruction for capturing a moving image.

Abstract: An image pickup device includes an optical system, an image pickup unit that captures a subject image through the optical system and generates a captured image, and a controller that calculates an evaluation value from a region corresponding to an AF frame in the captured image and drives the optical system according to the calculated evaluation value to perform an automatic focus operation. The controller includes a normal illumination mode set when brightness of the captured image is a predetermined value or more, and a first low-illumination mode and a second low-illumination mode set when the brightness of the captured image is less than the predetermined value. In the first low-illumination mode, a first automatic focus (AF) frame that is larger than an AF frame set in the normal illumination mode is set. In the second low-illumination mode, a second AF frame that is smaller than the first AF frame is set.

Abstract: The image capture device includes an optical system including a focus lens, a CCD that captures a subject image input via the optical system and generates an image signal, an image processor that generates image data by performing predetermined processing on the image signal generated by the CCD, and a controller. The controller performs a scan operation for detecting a focus position for each of a plurality of partial regions of image data while moving the focus lens and records a moving image by moving the focus lens while switching a moving speed of the focus lens based on information on the focus position obtained for each of the plurality of partial regions as a result of the scan operation. The plurality of partial regions is a plurality of regions obtained by dividing an image region of the image data.

Abstract: An imaging apparatus includes an imager, and a controller. The imager is configured to capture a subject image formed via an optical system including a focus lens, to generate image data. The controller is configured to control a focusing operation for adjusting a position of the focus lens along an optical axis in the optical system according to an evaluation value for a focus state. In response to an instruction to reduce or increase a distance to a subject to be focused, the controller is operable to shift a start position to a direction according to the instruction in directions along the optical axis, the start position being a position of the focus lens for starting the focusing operation. The controller is operable to start the focusing operation from the start position after the shift.

Abstract: An imaging apparatus includes: an imager to capture a subject image via an optical system including a focus lens to generate image data for each first frame period; a recorder to intermittently record image data for each frame captured by the imager in a second frame period; a focusing driver to adjust a focus lens position; and a controller to perform image processing for scaling an image indicated by the image data based on the focus lens position. The focusing driver repeats moving and stopping the focus lens alternately. When image processing of the scaling is performed on image data to be recorded by the recorder, the controller adjusts a timing at which the focusing driver starts movement of the focus lens to a timing at which a thinned-out frame is captured, and scales an image indicated by image data that is a frame at stopping of the focus lens.
