Abstract:
A lens assembly and an electronic device are provided. The lens assembly and/or the electronic device includes a lens barrel, a housing configured to accommodate the lens barrel on one surface of the housing, and an image sensor assembly mounted to the other surface of the housing, the image sensor being configured to rotate around an optical axis of the lens barrel. The image sensor assembly includes a ring-shaped rotation member facing the other surface of the housing, and a plurality of balls interposed between the rotation member and the other surface of the housing. The rotation member rotates on a plane perpendicular to the optical axis.
Abstract:
A method for controlling a hearing aid using a portable terminal is provided. The method includes taking a photo, generating a control signal to control a hearing mode of the hearing aid according to an analysis of a surrounding condition based on the photo, and transmitting the control signal to the hearing aid.
Abstract:
An optical measuring method includes generating a Bessel beam, filtering the Bessel beam to generate a focused Bessel beam, vertically irradiating the focused Bessel beam onto a substrate in which an opening is formed, and detecting light reflected from the substrate to obtain an image of a bottom surface of the opening.
Abstract:
A method of operating an electronic device is provided. The method includes transmitting, by the electronic device, a control signal for controlling a microphone sensitivity of a hearing aid, to the hearing aid, and transmitting a reception signal from a counterpart electronic device to the hearing aid.
