An optical system and a method for adjusting diopter are provided. The optical system includes an eyepiece (10), a half mirror (20), a display screen (30), a first motor (40) coupling with the display screen (30), an image sensor (50), and an image analysis system (60) coupling with the display screen (30), the first motor (40), and the image sensor (50). The first motor (40) controls the display screen (30) to move back and forth along the first optical axis (70). The image sensor (50) converts reflected light signals into fundus images. The image analysis system (60) controls the first motor (40) to adjust a distance between the display screen (30) and the half mirror (20) according to the fundus images.

An image sensing apparatus has a light sensitive area and a control unit. The light sensitive area registers image data in response to an incoming amount of light, and is operable in an active mode wherein image data can be read out there from as well as in a standby mode wherein image data cannot be read out. The control unit produces a control signal setting the light sensitive area to operate in the active mode and the standby mode respectively in a cyclic manner during an operation period, which preferably encompasses multiple data frame read-outs of image data from the light sensitive area.

[Object] To provide an information processing device, an information processing method, and a program. [Solution] An information processing device including: an acquisition unit configured to acquire attention information regarding an attention target of a user; and a zoom control unit configured to perform zoom control of a camera on the basis of non-zoom control of the camera and the attention information when the non-zoom control is performed on the basis of the attention information.

The imaging apparatus includes a first display device, a second display device, an eyepiece sensor that detects that an object approaches the first display device, and a controller that switches the eyepiece sensor to be valid and invalid. The controller sets the eyepiece sensor to be invalid when the first display device is not inclined while the second display device is inclined. The controller sets the eyepiece sensor to be valid when the first and second display devices are inclined.

An information processing system that acquires first image data captured by a first camera unit disposed on a first side of a housing; acquires second image data captured by a second camera unit disposed on a second side of the housing, which is opposite to the first side of the housing; and modifies the second image data based on the first image data.

An image pickup apparatus includes a detection unit configured to detect proximity of an object to a viewfinder, a line-of-sight detector configured to detect as line-of-sight information, using an eyeball image of a user who peers through the viewfinder, a position that the user gazes at in a display unit disposed inside the viewfinder, and a processor configured to determine whether or not to prohibit the display unit from being set to a non-display state using a feature in the eyeball image, in a case where the line-of-sight information is not detected, and not to set the display unit to the non-display state, in a case where the processor determines that the display unit is prohibited from being set to the non-display state.

An electronic apparatus comprises an eye approach detection unit configured to detect an objective approaching to a finder, a sight line detection unit configured to detect a sight line position to a display unit that is arranged in the finder, and a control unit configured to perform control to drive the sight line detection unit and stop driving the approach detection unit when it is detected by the approach detection unit that an objective has been approached to the finder, wherein the control unit performs control to, based on a detection result of the sight line detection unit, drive the approach detection unit from a state in which a driving of the approach detection unit is stopped, and stop driving the sight line detection unit while driving the approach detection unit.

An information processing system that acquires first image data captured by a first camera unit disposed on a first side of a housing; acquires second image data captured by a second camera unit disposed on a second side of the housing, which is opposite to the first side of the housing; and modifies the second image data based on the first image data.

A diagnosis supporting device includes a display, an imaging unit configured to capture a subject, an eye gaze detector configured to detect an eye gaze direction of the subject from a captured image captured by the imaging unit, a gaze point detector configured to detect a gaze point of the subject in a display region of the display, based on the eye gaze direction, an output controller configured to display, on the display, a diagnosis image that includes a person image and a geometric pattern image, and in which at least one of contrast, color density, and a degree of transmittance of the person image or the geometric pattern image is changed over time, and an evaluator configured to calculate an evaluation value of the subject, based on the gaze point detected by the gaze point detector when the diagnosis image is displayed.

An information processing apparatus includes an eyeball position estimation unit that estimates an eyeball position of a user in a pupil-corneal reflection method on the basis of a captured image including an eye of the user captured when the eye of the user looking at a display surface is irradiated with light; a discrepancy estimation unit that estimates an amount of discrepancy between an eyeball position on the display surface and a visual field center of the display surface, the eyeball position being identified on the basis of the eyeball position; and an operation instruction unit that issues an operation instruction to adjust a position of a device including the display surface on the basis of the estimated amount of discrepancy.
