Abstract: Disclosed herein is an ultrasonic sensor control device that controls an ultrasonic sensor device configured to transmit and receive ultrasonic waves. The ultrasonic sensor control device includes a transmission control section configured to control transmission of a transmission ultrasonic wave at a first frequency through the ultrasonic sensor device, a reception section configured to receive a reception ultrasonic wave through the ultrasonic sensor device, and a device control section configured to control the ultrasonic sensor device to set given frequencies as a transmission frequency of the transmission ultrasonic wave and a reception frequency of the reception ultrasonic wave. The device control section changes the reception frequency in such a manner that the reception frequency is a frequency different from the first frequency during a first period including at least a transmission period during which the transmission ultrasonic wave is transmitted.

Abstract: The present disclosure describes a projector which has: an image projection portion; an image provision portion that provides a projection image to the image projection portion; a deviation movement detection portion that detects a deviation movement of the image projection portion; and an image process portion that based on detection by the deviation movement detection portion, shifts the image provided by the image provision portion in a direction where the deviation movement is corrected. According to this, even if an image projection function does not include a deviation correction function, it is possible to perform the deviation correction by means of the image process.
