An image processing apparatus capable of shifting to a power saving mode. The image processing apparatus includes a storing unit configured to store a document in a storage device, a notification unit configured to periodically notify an apparatus of a predetermined destination of information about a document that has been newly stored by the storing unit into the storage device, and a control unit configured to restrict shifting to a power saving mode in which the notification unit cannot make the notification after storage of a document by the storing unit has been completed and until the notification unit notifies at least information about the document.

An image forming apparatus includes: a controller that controls the image forming apparatus; a memory that stores noise levels produced by a plurality of devices constituting the image forming apparatus during operation of the devices; and a microphone that accepts a speech instruction for the image forming apparatus. The controller accepts a job, detects a speech level from the speech accepted by the microphone, compares the detected speech level with a noise level that corresponds to the job to be executed in the image forming apparatus and that has been read from the memory, and controls, based on a result of the comparison, which one of a process of accepting the speech instruction and a process of executing the job in the image forming apparatus should be preferentially performed.

An image forming apparatus includes a detection unit configured to detect an object, a reception unit configured to receive an operation of a user, and a shifting unit configured to shift, if the detection unit detects an object, a power state of the image forming apparatus from a first power state to a second power state different from the first power state, and shift, if the reception unit receives an operation of a user, the power state of the image forming apparatus from the second power state to the first power state.

An information processing apparatus includes a processor, an information storage unit, a voltage supply unit, and a control unit. The information storage unit is configured to hold information indicating a voltage to be supplied to the processor. The voltage supply unit is configured to supply a predetermined voltage to the processor based on the information stored in the information storage unit. The control unit is configured to detect an alteration in software to be executed by the processor, and to make a setting for supplying a predetermined voltage to a power source unit based on the information stored in the information storage unit.

This image forming apparatus includes, for example, a first control unit provided on a first control board and configured to comprehensively control the image forming apparatus, a second control unit provided on a second control board different from the first control board and configured to control a function provided by the image forming apparatus, and an image processing unit provided on the second control board and configured to execute image processing. The second control unit causes the image processing unit to execute initialization processing when power is supplied, stops supplying clocks to the image processing unit upon completion of the initialization processing, and resumes supplying clocks to the image processing unit in accordance with generation of a start event of instructing to start a function provided by the image forming apparatus.

An image forming apparatus includes a power supply part that supplies electronic power in two different power modes (first and second modes), a communication part that includes a transmitting and receiving part that receives a network packet in the both modes, and a determination part that stores filter information and determines whether or not the network packet matches one of filter settings, a determination control part that performs a rewrite operation to repeatedly rewrite the filter information while running in the second mode, a power supply control part that transits the power mode of the power supply part from the second mode to the first mode based on a determination result of the determination part, a packet transmitting and receiving part that receives the network packet supplied from the transmitting and receiving part in the first mode and stops an operation of itself in the second mode, and an image forming part stops an operation of itself in the second mode.

The image forming apparatus of the present invention is a semiconductor integrated circuit including: a first image processing module; a second image processing module; a first SRAM configured to temporarily store image data for which the first image processing has been performed by the first image processing module; a second SRAM configured to store a parameter for performing the second image processing for image data that is input to the second image processing module; and a control unit. The control unit stops power supply to the first SRAM, continues to supply power to a storage area of the second SRAM in which the parameter is stored, and stops power supply to a control area for writing data to the storage area of the second SRAM based on that a condition to cause the semiconductor integrated circuit to make a transition into a power-saving mode is satisfied.

A human presence sensor unit in which an ultrasonic wave sensor is mounted is fixed to a frame sheet metal of an image forming apparatus with a pedestal interposed therebetween. The pedestal is made of a synthetic resin material, and the frame sheet metal is made of a metal material. As the pedestal and the frame sheet metal are made of different materials, a difference in the acoustic impedance is produced between the pedestal and the frame sheet metal.

Techniques are described for implementing an immediate-mode camera for integration into portable personal electronic device (PPED) environments. Embodiments of the IMC can include an integrated digital camera that can be triggered directly by one or more user interface components, without involving waking up the application processor, waking up display components, waking up digital camera components, and/or starting up camera-related applications. For example, if a user's smart phone is locked, and the user desired to capture a photo, the user can interact with particular UI components in a particular manner, thereby directly triggering capture of image data by the IMC substantially without delay. Implementations of the IMC can involve a low-power, always-on digital camera that is directly controllable by one or more always-on user interface components. The IMC components can be in communication with an always-on region of the application processor via a fast hardware interface.

An image forming apparatus includes a detection unit configured to detect an object, a reception unit configured to receive an operation of a user, and a shifting unit configured to shift, if the detection unit detects an object, a power state of the image forming apparatus from a first power state to a second power state different from the first power state, and shift, if the reception unit receives an operation of a user, the power state of the image forming apparatus from the second power state to the first power state.
