An apparatus includes a forming unit, a receiving unit configured to receive an instruction, a reading unit configured to read an image based on the instruction, a memory configured to store a plurality of pieces of pixel data, a first output unit configured to output the plurality of pieces of pixel data at an output cycle, a data bus configured to transfer the pixel data, and a controller configured to operate a first process and a second process. The forming unit forms an image based on the plurality of pieces of pixel data transferred via the data bus. In a case where the receiving unit receives the instruction, the controller sets the output cycle as a first cycle if the controller is not operating the second process, or sets the output cycle as a second cycle longer than the first cycle if the controller is operating the second process.

An image-reading device, such as optical code readers used in retail environments to scan objects, is configured to select from various operational modes. The operational modes are selected based on an application of the image-reading device, such as optical code identification or image recognition. Red, white, and other color light sources are activated in patterns corresponding to an illumination sequence of the selected operational mode, while imagers are activated to capture an image based on an exposure pattern of the selected operational mode. Further, a repeating series of light pulses having different portions of light is provided. Various imagers are configured to capture images over one of the portions. This allows an operator to perceive one continuous light pattern, yet allows various imagers to capture an image under different light conditions used for different applications of the image-reading device.

An image processing apparatus that is capable of executing a scan image process and another image process in parallel without reducing a scanning speed. A scanner scans an image of a document and generates image data. An image processor applies an image process to image data. A scanner controller transfers image data to the image processor from the scanner through a data bus. A controller determines whether a first image process applied to the scanned image data is executed in parallel with a second image process and determines whether a setting about the first image process is a predetermined setting. The controller sets a transfer speed to a first speed when the image processes are not executed in parallel and sets the transfer speed to a lower second speed when the image processes are executed in parallel and when the setting about the first image process is the predetermined setting.

A computing device comprising a processor, the processor configured to: receive, from an image capture system, an image captured in an environment and image metadata associated with the image, the image metadata comprising an image capture time; receive a sound recognition message from a sound recognition module, the sound recognition message comprising (i) a sound recognition identifier indicating a target sound or scene that has been recognised based on captured audio data captured in the environment, and (ii) time information associated with the sound recognition identifier; detect that the target sound or scene occurred at a time that the image was captured based on the image metadata and the time information in the sound recognition message; and output a camera control command to said image capture system based on said detection.

A media processing apparatus includes a medium drive, a label printer, and a medium-processing-apparatus control section. When the medium-processing-apparatus control section receives a first photographic data file, the medium-processing-apparatus control section causes the medium drive to write the first photographic data file to a medium. After the medium-processing-apparatus control section has received the first photographic data file, the medium-processing-apparatus control section receives a second photographic data file and causes the medium drive to write the second photographic data file to the medium. When the medium-processing-apparatus control section receives a medium close command from a control apparatus, the medium-processing-apparatus control section terminates write processing by the medium drive in response to the received medium close command, and causes the label printer to perform printing.

A system and method for providing seamless, alternative or concurrent control of document processing devices by multiple devices includes a processor, memory, digital data interface and user interface configured to receive user input, such as setting job properties on a multifunction peripheral. A settings screen is displayed for receiving user settings for job properties, such as finishing options, duplex options or scan resolution. As a user makes selections, they are reflected on the user interface and propagated to user interfaces of one or more alternative devices. A user may commence entering settings on one device and switch seamlessly to continue entering settings at the same point on an alternative device.

A printing apparatus comprises a plurality of sending units that respectively send signals; a plurality of receiving units provided on a printhead and respectively corresponding to the plurality of sending units, the plurality of receiving units receiving signals via a signal line; and a phase adjustment unit that, based on a phase difference of a plurality of signals respectively received by the plurality of receiving units, controls and outputs a delay of the plurality of signals. Each of the plurality of sending units sends a phase adjustment signal for phase adjustment to be performed by the phase adjustment unit, and a phase adjustment signal sent by a first sending unit includes a signal having a coordinate phase and an opposite phase with respect to a phase adjustment signal sent by a second sending unit.
