An electronic apparatus includes a detection unit that detects eyes from an image, a selection unit that selects one eye from the eyes detected by the detection unit, an operation unit that accepts an operation of causing the selection unit to select an eye different from the selected eye, and a display unit that displays an indication superimposed on an image indicating that the eye is selected by the selection unit.

Electronic apparatus, camera, and program for selecting features on an image

A focus adjustment control apparatus is provided which includes: a focus detection unit that calculates an evaluation value with regard to contrast of an image via an optical system to detect a focus adjustment state of the optical system; an acquisition unit that acquires from a lens barrel at least one of a maximum value and a minimum value of an image plane movement coefficient that represents correspondence relationship between a movement amount of a focus adjustment lens included in the optical system and a movement amount of an image plane; and a control unit that uses at least one of the maximum value and the minimum value of the image plane movement coefficient to determine a drive speed for the focus adjustment lens when the focus detection unit detects the focus adjustment state.

Focus adjustment apparatus, imaging apparatus and lens barrel

A lens barrel attached to an imaging device, including a focus lens unit that is movable in an optical axis direction; an actuator that moves the focus lens unit along the optical axis direction; a drive control section that controls drive of the actuator; and a setting section that is capable of setting a movement range of the focus lens unit to be one of a first range and a second range that differ from each other with respect to at least one of one end and another end, each range defining the range in which the focus lens unit is allowed to move. Even when the movement range of the focus lens unit is set by the setting section to be one of the first range and the second range, the drive control section removes the setting of the movement range when instructions are received from the imaging device.

Lens barrel, replacement lens, imaging device, and control program

This invention includes an imaging device that photographs a subject image, a first storage device that stores image data output from the imaging device at a first time interval, a display device that reads the image data stored in the first storage device at the first time interval and display the image data, a second storage device that reads the image data stored in the first storage device at a second time interval and stores the image data and a feature extraction device that extracts a feature section of the subject based upon the image data stored in the second storage device. Therefore, image data output from the imaging device for an image display is once stored in the second storage device and the feature section is extracted from the stored image data, so an extraction is not affected by an update of the first storage device.

A focus adjusting apparatus includes an imaging unit, a calculation unit, a detection unit, and a control unit. The imaging unit is configured to generate an imaging signal of an image formed by an optical system. The calculation unit is configured to calculate based on the imaging signal a focus evaluation value in accordance with a focus adjustment position of the optical system. The detection unit is configured to detect a state with respect to a size of the image. The control unit is configured to control focus adjustment of the optical system based on a rate of change in the focus evaluation value and the state with respect to the size of the image.

Focus adjusting apparatus, camera including the same, and method for adjusting focus of optical system

An auto-focus (AF) camera enables AF operation with high speed and enhanced accuracy. The AF operation encompasses step-scanning the focus lens of the camera from the closest focal position to infinity, or vice versa. In one embodiment, the steps in the step-scanning are made smaller around a position judged to be close to the focus position, and the steps are made larger at other positions.

A camera includes a first image pickup section that photographs a recording-purpose image, a viewfinder optical system, a second image pickup section, a mounting section, a display processing section, a displaying section, and a controlling section. The viewfinder optical system has an eyepiece section that can observe an optical image of a subject with a light flux from a photographing optical path of the first image pickup section. The second image pickup section photographs a view confirming image from an optical path different from that of the first image pickup section. The mounting section acquires focal-length information of an interchangeable lens. The display processing section executes display processing that superimposes a frame indicating a range of a field angle of the first image pickup section, onto the view confirming image. The displaying section provides the eyepiece section with the view confirming image having been processed with the display processing. The controlling section switches between a first state to provide the eyepiece section with the optical image and a second state to provide the eyepiece section with the view confirming image. Then, the displaying section changes a size of a frame based on the focal-length information when in the second state.
