Devices and methods are provided for eye-tracking, e.g., including a freeform optical assembly and/or a modular design. In an exemplary embodiment, a device and method are provided that includes a wearable device on a user's head, the wearable device including a scene camera oriented to capture images of the user's surroundings. The user may perform a predetermined action with the user's eye to activate a photo feature of the wearable device, gaze at a region within the user's surroundings, the wearable device determining a focal point and limited field-of-view for the camera imaging field based on the center point, and activate the camera to capture an image of the limited field-of-view centered around the focal point.

A system controls a brightness of an augmented reality (AR) eye-mounted device. The system includes an eye-mounted display, a photodetector system, and a controller. The eye-mounted display includes a contact lens and a femtoprojector. The femtoprojector is contained in the contact lens and is configured to project an AR image to a user's retina. The AR image is overlaid on an external scene viewed by the user through the contact lens. The photodetector system detects a brightness level of the external scene. Based on the brightness level of the external scene, the controller adjusts a brightness level of the AR image projected to the user's retina. In some embodiments, the eye-mounted display receives image data defining the AR image and the controller adjusts a bit depth of the image data based on the brightness level of the AR image.

Image collection is provided, e.g., a system includes a gaze point detection device for detecting a location of a gaze point of a user with respect to the user, and an image collection device for focusing and collecting a first image according to the location of the gaze point with respect to the user. The gaze point detection device comprises a fundus image collection module for collecting a second image of a fundus of a user, an adjustable lens module for adjusting an imaging parameter of an optical path between the fundus image collection module and an eye and an image processing module for calculating the location of a gaze point of the user with respect to the user according to the imaging parameter. The system and method of the present application can increase the focusing accuracy and the focusing speed of an image collection apparatus.

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.

A method for detecting the viewing direction of a person having a visual aid includes providing at least one optical property of a visual aid of the person, observing at least one eye of the person, and correcting data ascertained from the observation based on the at least one optical property of the visual aid. An apparatus designed to detect the viewing direction of a person includes an observation device set up to observe at least one eye of the person, a data record containing at least one optical property of a visual aid of the person, and a computing device equipped to correct the observation based on the data record.

[Object] To provide an information processing apparatus that can adjust a position of a device to make an eyeball position of a user agree with a visual field center of a display surface.

[Solution] There is provided an information processing apparatus including: an eyeball position estimation unit configured to estimate 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 configured to estimate 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 configured to issue an operation instruction to adjust a position of a device including the display surface on the basis of the estimated amount of discrepancy.

An electronic device that has a line-of-sight detection function and is capable of suppressing the execution of an operation different from the intention of a user, and a control method therefor are disclosed. The device has a function for detecting coordinates on an image at which a user is gazing as point-of-gaze coordinates. The device, in a case where a movement of the point-of-gaze coordinates has been detected, measures a duration of the point-of-gaze coordinates after the movement. The device further determines that the movement of the point-of-gaze coordinates with the duration larger than a time threshold is a viewpoint movement that is intended by the user, and determines that the movement of the point-of-gaze coordinates with the duration equal to or smaller than the time threshold is a viewpoint movement that is not intended by the user.

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.

An electronic apparatus includes a control unit that performs control to acquire first orientation information indicating a first orientation of the body and first line-of-sight information about the user's line-of-sight, of a case where a first eye tracking calibration display is displayed on the screen, acquire second orientation information indicating a second orientation of the body different from the first orientation and second line-of-sight information about the user's line-of-sight, of a case where a second eye tracking calibration display is displayed on the screen, and cause, in a case where the second orientation information is different from the first orientation information, the screen to display a predetermined display that prompts the user to change the orientation of the body to the first orientation.

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.
