A paper jam indication detection device detects an indication that a paper jam will occur in a paper feed device. The paper jam indication detection device includes: a sound collector that collects a friction sound produced by friction between a plurality of sheets of paper when the paper is fed from a holder holding the plurality of sheets of the paper; an indication detector that detects an indication that a paper jam will occur in the paper feed device based on a decrease in the friction sound collected by the sound collector; and a signal outputter that, when the indication is detected by the indication detector, outputs, to the paper feed device, a signal for stopping the paper from being fed from the holder.

Paper jam indication detection device, paper jam indication detection method, and recording medium

A sound pickup device for picking up a target sound includes: a first input interface that inputs image data generated by a camera; a second input interface that inputs an audio signal output from a microphone array; a controller that determines a sound pickup direction in which the target sound is picked up, based on the image data and the audio signal; and an output interface that outputs information to be presented to the user. The controller determines whether an image indicated by the input image data and an audio sound indicated by the input audio signal are in a predetermined state. When determining that the image and the audio sound are in the predetermined state, the controller causes the output interface to output an instruction to the user, and inputs additional image data and an additional audio signal after the instruction is output, to determine the sound pickup direction.
