    摘要： To provide an image display device capable of improving display at a fovea of an eye, which is the most important part in a display range, such that display at the fovea of the eye is not darkened. There is provided an image display device including: at least one optical element unit including two optical elements facing each other, in which one optical element unit included in the at least one optical element unit includes a first optical element and a second optical element, an image is formed on the basis of image display light which transmits through the first optical element and is emitted to outside of the image display device, the first optical element has a deflection function of deflecting incident light which has a predetermined wavelength and is incident on the first optical element at a predetermined incidence angle to a side of the first optical element on which the incident light is incident, and emits first diffracted light deflected by the deflection function, the second optical element has a lens function for the first diffracted light which has a predetermined wavelength and is incident on the second optical element at a predetermined incidence angle, and a direction of the incidence angle of the incident light and a direction of a diffraction angle of the first diffracted light are different from a direction of an optical axis of the second optical element.

    摘要： A master clock signal for an image capture device and a light emission device is accessed. The master clock signal is divided to generate a high frequency clock signal. A frame timer is used to measure a frame time of the image capture device based on cycles of the high frequency clock signal. Based on an exposure timing signal from the image capture device, estimating an exposure start time for the image capture device; is estimated. Based on the estimated starting time, the light emission device begins emission of a positional tracking pattern at the estimated starting time and for a duration determined by the measured frame time of the image capture device.

    摘要： The present disclosure provides smart glasses including a frame (10), an imaging system (20), and a first lens (30), wherein the imaging system (20) includes an image source assembly (21) configured to emit light for forming an image, and an optical assembly (22) configured to change an optical path of the light to project light in a direction of a first side of the image source assembly (21), the image source assembly (21) and the optical assembly (22) being both provided on the frame (10); and the first lens (30) is provided on the frame (10) and located on a second side of the image source assembly (21), with a gap being formed between the first lens (30) and the optical assembly (22), and the gap being sealed to form a sealed space. The gap between the first lens (30) and the optical assembly (22) of the smart glasses is sealed to form the sealed space, such that dust will not be deposited therein, so there is no need to disassemble them in order to clean the gap therebetween, scratches will not be produced on the first lens (30) and the optical assembly (22), and the difficulty of maintenance for a user can be reduced. Moreover, a detachable connection structure can be omitted, which is beneficial to simplifying the structure of the smart glasses, and conducive to the lightness and thinness of the smart glasses, and can improve a user's wearing experience.
