Abstract
An imaging device includes an image sensor, a controller, and an annunciator. The image sensor is configured to capture an object image entering via an optical system. The controller is configured to control focusing operation to focus the object image by the optical system. The annunciator is configured to output focusing sound that has a predetermined frequency characteristic according to the focusing operation. The frequency characteristic of the focusing sound includes a first sound component based on first frequency, and a second sound component based on second frequency that is higher than the first frequency and lower than twice frequency of the first frequency.

An imaging device comprising:
- an image sensor configured to capture an object image entering via an optical system;
- a controller configured to control focusing operation to focus the object image by the optical system;
- and
- an annunciator configured to output focusing sound indicating that the imaging device is in focus, according to the focusing operation,
- wherein the focusing sound has a chord frequency characteristic of the focusing sound includes a first sound component based on first frequency, and a second sound component based on second frequency that is higher than the first frequency and lower than twice frequency of the first frequency.
