    Abstract: A signal processing device includes an input interface, an image processor, an audio processor, and a controller. The input interface receives signals of a video and an audio acquired concurrently in a space where subjects exist. The image processor recognizes subject images in the video, to determine a first type of area where each subject exists. The audio processor recognizes sound sources in the audio, to determine a second type of area where each sound source exists in the space, independently of the first type of area. The controller uses the first and second types of areas to judge coincidence or non-coincidence between a position of the each subject and a position of the each sound source, to determine a combination of a subject and a sound source whose positions coincide with each other. The controller selectively determines the subject image to be output that corresponds to the combination.

    Abstract: The electronic device of the present disclosure has a mounting section, a voltage determiner, and an attach-detach detector. The mounting section accepts a removable, externally-connected device and connects to a data line into which a unit signal having a data period for transmitting a data signal and a detection period for transmitting a detection signal is fed from the externally-connected device. The voltage determiner determines an electric potential of the data line so as to have a first logical value when the externally-connected device is detached from the mounting section. The attach-detach detector detects whether the externally-connected device is mounted on, or detached from the mounting section by detecting the detection signal of the first logical value determined by the voltage determiner or a second logical value.

    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.

    Abstract: An imaging apparatus comprising: a display configured to display information; an image sensor configured to capture an image of a subject to generate image data; an audio input device configured to input audio to generate an audio signal indicating sound to be collected during image capturing with the image sensor; a detector configured to detect a subject region which corresponds to the subject in the image data; a controller configured to determine a main subject and a sound collection target for the audio signal, according to a subject region detected by the detector. When the detector detects a plurality of subject regions, the controller controls the display to display first identification information indicating a subject which is the main subject and is the sound collection target and second identification information indicating a subject which is different from the main subject and is the sound collection target distinguishably from each other.
