An image forming apparatus includes a main CPU, and, in an unused period in which the image forming apparatus is not used, the main CPU detects whether or not a person exists within a human detection range, on the basis of an output of a human detection sensor. When a person has been detected, by outputting a notification voice regarding an intruder, which indicates that the intruder has been detected, from a speaker, the main CPU notifies the surroundings of the image forming apparatus and also transmits an electronic mail including a message indicating that the intruder has been detected to an address that has been registered in advance and thereby notifies a user of a terminal of the address of the detection of the intruder.

The present invention offers a system including a transmission unit configured to transmit, based on a reception of predetermined information, first notification information for causing an audio control device to audibly notify a user of a first message related to a printing apparatus, and second notification information for causing a terminal device outside the audio control device and outside the printing apparatus to notify, through a notification screen, the user of a second message related to the printing apparatus and including a message not included in the first message.

A display device includes: a display unit capable of displaying a setting screen having an input area for an input value and a keypad screen having soft keys on the same screen; a determiner configured to determine an acceptable input value range of the input area displayed on the display unit; and a display controller configured to display only soft keys on the keypad screen, wherein the keypad screen has a fixed area in which the soft key is fixedly displayed and a variable area in which the soft key is variably displayed, the soft keys are classified into a common key and an individual key other than the common key, and the display controller displays the common key in the fixed area of the keypad screen and the individual key in the variable area of the keypad screen out of the soft keys.

A print apparatus registers information of the print apparatus in a server via an external access point based on an instruction provided via an operation screen of the print apparatus, obtains print data when an audio control device receives a print instruction by audio so that the server generates the print data, and executes a print process based on the obtained print data.

An image forming apparatus combines a plurality of sub-movies representing operation procedures to be performed to perform maintenance on the image forming apparatus and plays the combined sub-movies sequentially as one movie. In response to stopping the movie being played, the image forming apparatus displays a replay mark for use to issue a command to replay the movie from the beginning of a sub-movie corresponding to a position where the movie is stopped.

An image processing system includes a reception unit that receives an image forming instruction from a user, a retaining unit that retains the image forming instruction in association with the user, an acceptance unit that accepts an execution instruction from the user; an authentication unit that performs authentication of the user, and an image forming unit that executes the image forming instruction retained by the retaining unit in association with the authenticated user. The image forming unit executes the image forming instruction without accepting the execution instruction by the acceptance unit in a case where the authentication unit completes the authentication and cancellation of execution by the user is not present within a holding time.

An image processing system capable of managing image data using a plurality of boxes, comprises a microphone that obtains a sound, an obtaining unit that obtains a user identifier based on voice information of a user obtained via the microphone, a specifying unit that specifies one box among the plurality of boxes based on specification information including at least the user identifier, and an informing unit that informs the user of information related to the specified one box.

A digital camera with a printer is a digital camera with a printer and includes a communication unit that communicates with a digital camera with a printer that is another apparatus, and an image composition unit that generates a composite image in which a first image captured by the digital camera with a printer that is an owned apparatus and a second image captured by the other apparatus are composited, in which the communication unit transmits the composite image to the other apparatus. A user of the other apparatus can also obtain the composite image. Accordingly, the composite image can be enjoyed by capturing images using a plurality of cameras.

An apparatus includes: a generation unit that generates a PWM wave based on a sound signal; and a processing unit that converts the PWM wave to a square wave. The processing unit includes: a first counter that determines a pulse width of the PWM wave; a comparison unit that compares a first difference value, obtained by subtracting the pulse width in a second cycle being a cycle immediately preceding a first cycle from the pulse width in the first cycle, and a second difference value obtained by subtracting the pulse width in a cycle immediately preceding the second cycle from the pulse width in the second cycle; and an output unit that outputs the square wave while switching a state thereof in a case where a sign of the first difference value changes from that of the second difference value.
