A system includes a printing apparatus, and a printhead including a printing element. The printing apparatus includes a data transmission unit configured to transmit, to the printhead, a clock signal of a predetermined period and a data signal. The printhead includes a reception unit configured to receive the clock signal and the data signal, and an information transmission unit configured to transmit, to the printing apparatus, information concerning a reception result of the reception unit. When the data transmission unit transmits control data of the printing element as the data signal, a first period is set as the predetermined period. When the data transmission unit transmits, as the data signal, connection confirmation data for confirming connection of the printhead to the printing apparatus, a second period longer than the first period is set as the predetermined period.

An information processing apparatus includes a processor and a first device. The processor executes an operating system and a power control application, which operates on the operating system and controls a power mode of the information processing apparatus. The first device is connected to the processor to communicate with the processor, and notifies the operating system of a return time. The power control application notifies the first device of information indicating the power mode of the information processing apparatus. Based on the information notified by the power control application, the first device determines a return time of which the operating system is to be notified, and notifies the operating system of the determined return time. Based on the return time notified by the first device, the operating system determines a power saving state to which the processor is to shift, and shifts the processor to the determined power saving state.

It is possible to continue printing processing without suspension even in the case where print data is not prepared in time in continuous printing that is performed by continuously feeding sheets. An image forming apparatus includes: a generation unit configured to generate image data based on a print job; a determination unit configured to determine whether image data corresponding to a sheet passing a predetermined location of a conveyance path through which sheets are conveyed is prepared in time; and a control unit configured to perform, in the case where the determination unit determines that image data is not prepared in time, control to leave the sheet as a blank sheet by skipping processing to form an image for the sheet, and the control unit changes a printing order determined in advance in the case where the determination unit determines that image data is not prepared in time.

A communication apparatus includes a control unit configured to perform, in a case where the communication apparatus is operating in a connection setting mode and a predetermined process is completed, control to stop operation in the connection setting mode based on passage of a second time longer than a first time without performance of connection setting from a start of an operation of the communication apparatus in the connection setting mode.

An information processing apparatus includes a mode setting unit in which a value indicating whether a scanning device is for simplex scanning or duplex scanning is set up, an interface unit that controls whether to enable signal exchange with an external memory based on the value set up in the mode setting unit, and a transfer unit that retrieves image data from the external memory and transfers the image data to an image processing unit. When the value in the mode setting unit indicates that the scanning device is for duplex scanning, the interface unit enables signal exchange with the external memory, and the transfer unit transfers the image data retrieved from the external memory to the image processing unit. When the value in the mode setting unit indicates that the scanning device is for simplex scanning, the interface unit prohibits signal exchange with the external memory.

In a technique to implement document reading by making use of a mobile terminal and an image forming apparatus, control to cause an image of a document to be captured at accurate timing is important. The present invention is a mobile terminal capable of communicating with an image forming apparatus and the mobile terminal includes: an image capturing unit; an instruction unit configured to transmit discharge instructions to discharge a document to the image forming apparatus in which the document is set in a sheet feed unit; a state acquisition unit configured to acquire a state of the image forming apparatus by communicating with the image forming apparatus; and an image capturing instruction unit configured to detect timing at which the image forming apparatus discharges the document based on the state of the image forming apparatus acquired by the state acquisition unit and to give instructions to capture an image of the document to the image capturing unit at the timing.

An image forming apparatus which performs an adjustment operation at appropriate timing. Whether to execute a first or a second adjustment processes is controlled based on the number of sheets on which images are formed. A first adjustment operation is executed in a case where the number of sheets has reached a first number since a previous first adjustment process was executed. A second adjustment operation is executed in a case where the number of sheets has reached a second number since a previous second adjustment process was executed. The first adjustment operation is executed in a case where the number of sheets has reached the first number prior to a designated time by a predetermined period. The second adjustment operation is skipped in a case where the number of sheets has reached the second number prior to the designated time by the predetermined period.

A device and method allows a user to create a mark corresponding to a moment in time of a captured recording to provide later viewing of a portion of the recording corresponding to the moments in time.

System, Method and Apparatus for generating a collection of images, the technique including providing at least two mobile devices with a data processing unit, a storage memory and a camera integrated therein or connected thereto; providing a master system with a data processing unit and a storage memory or configuring of one of the mobile devices as master system and configuring of the other or of all mobile devices as slave systems; setting a recording criterion in the master system; transmitting the recording criterion to the slave systems; setting a series ending criterion in the master system; transmitting the series ending criterion to the slave systems; respectively performing a process for recording an image on each slave system as long as the series ending criterion is not fulfilled comprising the steps of recording at least one image with the camera of one of the slave systems whenever the recording criterion is fulfilled, and sending the image from the slave system to the master system together with a time stamp, a series number and/or another variable for grouping the image; saving each of the images sent respectively with their time stamp, their series number and/or their variable for grouping in the storage memory of the master system; and generating a series of images comprising the images sent in order according to their time stamp, their series number and/or their variable for grouping.

This invention provides a data processing apparatus operable to execute processing requested by an application, where the apparatus comprises a processing unit configured to, if there is an instruction for processing, execute the processing in accordance with a command list indicated by the instruction; and a control unit configured to, upon receiving a request for processing from the application, generate a command list corresponding to the request and instruct the processing unit to perform the processing, wherein the processing unit comprises a switching unit configured to, upon receiving, from the control unit, a second instruction during execution of a command list for a first instruction, switch to execution of a command list for the second instruction at a timing of execution of a command that is a control point preset in the command list for the first instruction.
