An information processing apparatus includes a storage unit configured to store information related to an activation of the information processing apparatus, a control unit configured to perform a control such that, in a case where the information stored in the storage unit relates to a first activation, the information processing apparatus is shifted into a standby state when power is supplied to the information processing apparatus, and in a case where the stored information relates to a second activation, the information processing apparatus is shifted into the standby state when the power is supplied to the information processing apparatus and also a signal input to the control unit is put into a particular state, and a power supply control unit configured to put the signal input to the control unit into the particular state when the information processing apparatus is not shifted into the standby state even when the power is supplied.

A CPU of an information processing apparatus (MFP) obtains device information regarding a secondary storage device provided in the MFP, and discriminates, based on the obtained device information, whether the secondary storage device is a type of storage device in which the number of shifts to a power saving state affects the lifetime of the storage device. The CPU determines, as a shift condition for the secondary storage device to shift to the power saving state, a shift time for the secondary storage device to shift to the power saving state, by determining the shift time for the type of storage device in which the number of shifts does not affect the lifetime to be shorter than the shift time for the type of storage device in which the number of shifts affects the lifetime.

An image forming apparatus is operable at least in a first power state and in a second power state, in which electric power consumption in the second power state is less than electric power consumption in the first power state. The apparatus includes a detection unit formed by a plurality of elements disposed to detect the temperature of an object, and a control unit configured to control the image forming apparatus in such a way as to shift from the second power state to the first power state based on a detection result obtained by the detection unit at first timing and a detection result obtained by the detection unit at second timing.

An image forming apparatus includes a display having a function of editing input image data and a function of displaying page images immediately after reading in order. When a first type of instruction to change shape of an image formed on a recording medium is given, the edition is not reflected on a document display mode screen image, and when a second type of instruction to edit page by page the recording medium having images formed thereon is given, the edition is reflected on the document display mode screen image. By switching between a finish preview screen image and the document display mode screen image, the image after edition and the image immediately after reading can be compared easily.

In one example, a printer with parallel/serial operational sequencing includes an engine control unit and an image processor unit each coupled to a set of sub-systems. A network unit is coupled to the image processor unit to monitor network packets while the engine control unit, the set of sub-systems, and the image processor unit are in sleep states. When a first predetermined packet is received, the network unit signals with a first modulation signal that the image processor unit is to awaken first before the image processor unit determines whether to awaken the engine control unit and any of the set of sub-systems. When a second predetermined packet is received, the network unit signals with a second modulation signal that the image processor unit, the engine control unit, and a portion of the set of sub-systems are to awaken at the same time.

An apparatus that causes a device to print an image includes at least one processor, and a display screen. A state of the apparatus is changed from a first state to a second state when an image is settled as a print target by a user, the first state being a state in which the at least one processor does not cause the device to print the image even if the apparatus is put close to the device, and the second state being a state in which the at least one processor can cause the device to print the image if the apparatus is put close to the device. After the apparatus in the second state performs a short distance wireless communication with the device, the device prints the image.

An information processing apparatus comprises a detection unit detecting a moving body around the information processing apparatus and a distance to the moving body; a first image capturing unit having a first image capturing range; and a second image capturing unit having a second image capturing range, and performs authentication of the authentication target person based on captured image data. It controls so as to perform authentication based on image data captured by the first image capturing unit, and if the detected distance becomes shorter than a first distance and the authentication is not possible, it controls so as to perform authentication based on image data captured by the second image capturing unit.

An image forming apparatus includes a print engine, a power supply apparatus, and a processor. The print engine is to print an image. The power supply apparatus is to supply power to the image forming apparatus and have a zero cross detection circuit to output zero cross information of input alternating circuit (AC) power. The processor is to determine whether the AC power is input using an output signal of the zero cross detection circuit. In response to an operation mode of the image forming apparatus being a normal mode, the zero cross detection circuit outputs zero cross information on a full wave of the input AC power. In response to an operation mode of the image forming apparatus being a power-saving mode, the zero cross detection circuit outputs zero cross information on a half wave of the input AC power.

An image processing device capable of repeatedly sending internal data stored inside the device to a server at a predetermined timing, comprises: a hardware processor that: obtains the internal data from the inside the device at every data transmission timing; determines whether or not to send the latest internal data obtained at the current data transmission timing to the server based on a change in an operation status during a period from the previous data transmission timing to the current data transmission timing; and sends the latest internal data to the server when determining to send the latest internal data to the server.

An image reading apparatus includes a first posture detection unit that detects a first posture that is a posture of the apparatus main body when not in use, a second posture detection unit that detects a second posture that is a posture of the apparatus main body when in use, and a posture change detection unit that detects a change in a posture of the apparatus main body. When the first posture detection unit detects a switchover of the apparatus main body to the first posture in a first power supply mode in which power is supplied to the first posture detection unit, the second posture detection unit, and the posture change detection unit, the first power supply mode transitions to the second power supply mode in which a controller supplies power to only the posture change detection unit.
