    Abstract: An optical scan device includes an optical waveguide array, including a plurality of optical waveguides each of which propagates light along a first direction, that emits a light beam, the plurality of optical waveguides being arranged in a second direction that intersects the first direction, a phase shifter array including a plurality of phase shifters connected separately to each of the plurality of optical waveguides, a control circuit that controls a phase shift amount of each of the plurality of phase shifters and/or inputting of light to each of the plurality of phase shifters and thereby controls a direction and shape of the light beam that is emitted from the optical waveguide array, a photodetector that detects the light beam reflected by a physical object, and a signal processing circuit that generates distance distribution data on the basis of output from the photodetector.

    Abstract: This invention solves the problem that objects in the field of view of reading glasses using multifocal lenses for correcting ocular refractive errors such as presbyopia appear distorted. This image display device is provided with the following: a distance computation unit that computes the distance to a subject in a field-of-view image; a visual-acuity-information acquisition unit that stores visual-acuity information for the user in advance; a corrected-image generation unit that generates and outputs a corrected image on the basis of the field-of-view image and an eye image generated from the field-of-view image, the distance information, and the visual-acuity information; and a display unit that displays the corrected image by superimposing same onto the user's field of view. Since the corrected image is superimposed without the use of lenses, lenses being the cause of the abovementioned distortion, the user can see close objects clearly.

    Abstract translation: 本发明解决了使用多焦点透镜校正眼屈光不正(例如老花眼)的阅读眼镜领域中的物体看起来失真的问题。 该图像显示装置设置有:距离计算单元,其计算与视野图像中的被摄体的距离; 视敏度信息获取单元,用于预先存储用户的视敏度信息; 校正图像生成单元,其基于所述视野图像生成并输出校正图像,并且从所述视野图像生成的眼图像,所述距离信息和所述视敏度信息; 以及显示单元,其通过将校正图像叠加在用户的视野上来显示。 由于校正图像叠加而不使用透镜,所以透镜是上述失真的原因,用户可以清楚地看到近距离的物体。
