An augmented reality (AR) device including a variable focus lens of which a focal length may be changed by adjusting refractive power and adjusting the position of a focus adjustment region of the variable focus lens according to a direction of the user's view. The AR device may obtain an eye vector indicating a direction of the user's view using an eye tracker, adjust a refractive power of a first focus adjustment region of a first variable focus lens to change a focal length for displaying a virtual image, and complementarily adjust a refractive power of a second focus adjustment lens with respect to the adjusted refractive power of the first focus adjustment region.

A camera module and an electronic device are provided. The camera module includes a reflective member provided with a reflective and transmissive surface; a lens assembly and an image sensor, provided on a side of the reflective member; a filter reflection layer, provided on the reflective and transmissive surface; and a laser sensor, provided on a side of the reflective and transmissive surface facing away from an entrance surface. The filter reflection layer is capable of reflecting light of a first frequency band and transmitting light of a second frequency band. The first frequency band and the second frequency band are independent of each other.

An electronic apparatus comprises a sight position detection unit configured to detect region of a sight positon to a display unit which displays an object, and a control unit configured to perform control to, in a case where a state where the detected region of the sight position is not moving continues for a first time period, select an object corresponding to the region of the sight position, and in a case where a state where the detected region of the sight position is moving and a direction of movement of the region of the sight position and a direction of movement of an object satisfy a predetermined condition continues for a second time period, select the object.

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.
