A gaze detection apparatus according to the present invention, includes at least one memory and at least one processor which function as: a detection unit configured to detect a gaze of an eye that views a display surface, based on an eye image obtained by capturing the eye; and a determination unit configured to determine whether the detection of the gaze is in error, based on a current eye image and a past eye image.

A display apparatus includes an image display element, an eyepiece portion, an object window, and a reflection optical element disposed at a position between the eyepiece portion and the object window, the reflection optical element being configured to guide a picture displayed on the image display element to the eyepiece portion. The reflection optical element changes a state to a first state and a second state by changing a transmittance. In the first state, the picture displayed on the image display element is viewed via the eyepiece portion. In the second state, an image in which an image from the object window and an image displayed on the image display element are superimposed is viewed via the eyepiece portion.

An electronic device is configured to obtain an eye image in which an eye that looks at a display is captured. The electronic device includes at least one memory storing instructions; and at least one processor which executes the stored instructions causing the at least one processor to: perform line-of-sight detection, based on the obtained eye image; and provide, based on at least one of a position of a pupil image in the eye image and a number of corneal reflection images in the eye image, a predetermined notification regarding a method of adjusting a viewing state in which the display is visually perceived.

In an operation by line-of-sight input, a position (designated position) designated by a gaze point is easier to view after a determination operation is performed by a user than before the determination operation is performed. An electric device includes a detector configured to detect a gaze point on a display unit, and a control unit configured to display an indicator indicating the gaze point on the display unit, wherein, in a case where a setting to keep displaying the indicator even in a case where an operation is performed on an operation unit by the user is set, the control unit performs control, in response to an operation performed on the operation unit by the user, to display a display item at the gaze point and to display the indicator and the display item in a changed display order.

A display apparatus includes an image display element, an eyepiece portion, an object window, and a reflection optical element disposed at a position between the eyepiece portion and the object window, the reflection optical element being configured to guide a picture displayed on the image display element to the eyepiece portion. The reflection optical element changes a state to a first state and a second state by changing a transmittance. In the first state, the picture displayed on the image display element is viewed via the eyepiece portion. In the second state, an image in which an image from the object window and an image displayed on the image display element are superimposed is viewed via the eyepiece portion.

A gaze detection apparatus according to the present invention, includes at least one memory and at least one processor which function as: a detection unit configured to detect a gaze of an eye that views a display surface, based on an eye image obtained by capturing the eye; and a determination unit configured to determine whether the detection of the gaze is in error, based on a current eye image and a past eye image.

An electronic device comprising a display control unit configured to perform control to display a plurality of display items on a display, each display item corresponding to one of a plurality of setting items including a specified setting item; and a control unit configured to perform control to in case where the predetermined operation for the specified setting item is received and a line-of-sight input to a corresponding region for a display item corresponding to the specified setting item is received, display the display item corresponding to the specified setting item in a first display appearance, and in case where the predetermined operation for the specified setting item is received and a line-of-sight input to the corresponding region is not received, display the display item corresponding to the specified setting item in a second display appearance different from the first display appearance.

An observation apparatus includes an observation optical system and a line of sight detection system. The observation optical system includes, in order from a display element side to an observation side, an optical path splitter configured to split an optical path, and a first lens unit having a positive refractive power. The line of sight detection system includes a second lens unit configured to image light incident on the first lens unit and split by the optical path splitter. A predetermined condition is satisfied.

An image capture apparatus detects an eye approaching to a finder, switches between a locked state in which execution of a function corresponding to an operation on a touch panel having a display surface of a display unit capable of displaying a captured image as an operation surface is restricted and an unlocked state in which the execution of the function is not restricted, and performs control such that in the locked state, even if a specific operation is performed on the touch panel without detecting the eye approaching, predetermined processing corresponding to the specific operation is not executed, and the predetermined processing is executed in response to the specific operation on the touch panel being performed in a state where a predetermined condition including detection of the eye approaching is satisfied.

An imaging device detects a specific type object in a captured image, detects a position of a line-of-sight of a photographer, and controls so that: in case where the specific type object is not detected in the captured image, a main object to which a specific process should be applied is selected based on a predetermined condition within a first type zone including a detected line-of-sight input position, and in case where the specific type object is detected in the captured image, if the detected line-of-sight input position is included in a second type zone that is larger than the first type zone and includes the specific type object, the specific type object included in the second type zone corresponding to the line-of-sight input position is selected as the main object to which the specific process should be applied, regardless of the predetermined condition.
