An image processing apparatus includes a volatile main memory, a first non-volatile memory for storing a plurality of types of partial snap shot images, a second non-volatile memory from which information can be read faster than from the first non-volatile memory, for storing an entire snap shot image, and a processor. The processor reads a partial snap shot image corresponding to a state after change from the first non-volatile memory and updates a corresponding portion of the entire snap shot image in the second non-volatile memory.

An operational display device includes a display portion for displaying an image based on image data including a specific portion, a detection portion for detecting an orientation in which the display portion is held, and a display control unit for controlling a manner of display on the display portion. The display control unit causes an image of the specific portion to be displayed as being zoomed-in and rotated in accordance with an orientation of holding of the display portion when the orientation in which the display portion is held is changed from a first orientation to a second orientation.

Operational display device and method of controlling the same, and recording medium

An instruction input apparatus comprising: a display being provided with a display screen; an electrostatic touch panel being deposited on the front of the display screen on the display, the touch panel being configured to input instructions to the instruction input apparatus; an approach sensor being configured to detect a user's hand approaching to a part of frame of the touch panel; a coordinate identification portion being configured to identify the coordinate of a contact position at which the user touches on the touch panel; and a controller being configured to, if the approach sensor detects the user's hand approaching to the part of frame of the touch panel, change a contact detectable area of the touch panel so that the contact detectable area will exclude the coordinate of the user's contact position which is identified by the coordinate identification portion.

The present invention relates to an image forming apparatus that minimizes the consumption of power during physical formatting of the hard disk drive or the deletion of data therefrom and to a control method thereof. The image forming apparatus has a non-volatile storage unit that stores image data and a controller that executes at least one of the operations of initialization of the storage unit and deletion of the image data stored in the storage unit, and further includes as operating modes an image forming mode during which image formation is enabled and a power-saving mode during which power consumption is minimized, wherein the controller switches the operating mode to power-saving mode when initialization processing or image data deletion processing is begun.

Image forming apparatus and control method thereof

An image forming system includes a first image forming apparatus and a second image forming apparatus that are connected to each other via a network. The first image forming apparatus includes a transmitter unit transferring reproduced data of data for transfer to the second image forming apparatus via the network, a memory unit storing the data for transfer, and a data eraser unit erasing the data in the memory unit and transmitting an instruction to erase the corresponding data to the second image forming apparatus when a user inputs an instruction to erase the data for transfer. The second image forming apparatus includes a receiver unit receiving the transferred data, a memory unit storing the received data, and an eraser unit erasing the corresponding data in the memory unit according to the erase instruction transmitted from the first image forming apparatus.

An image forming apparatus using an exposure unit of a solid-scanning type such as an LED head, reads out linear distortion correction data of an LED unit, then, calculates an amount of correcting color deviation based on the read-out data, and after that, carries out address control for color deviation correction memory. Based on this control, the apparatus creates a reference resist patterns, calculates an amount of correcting the color deviation, and writes the calculated amount in the color deviation correction memory. After that, the apparatus reads out the linear distortion correction data, and adds the amount of correcting the color deviation that is determined by sensors, and the amount of the color correction based on the linear distortion correction data, thereby carries out address controls for the color deviation correction memory. This constitution allows correcting linear distortion of the exposure unit itself with ease and accuracy, and correcting positional deviation of the exposure unit occurring during product assembly and deviation in a linear arrangement of an LED head with accuracy.

A sample hold circuit is disposed which, in accordance with a hold signal, can selectively execute either of outputting a threshold signal output from an Automatic Threshold Control circuit, to a comparator as a threshold signal while allowing the voltage to be as it is, or outputting the signal while holding the voltage. Immediately before reception of synchronizing data in which signals of '1' and '0' are alternatingly repeated is ended, the voltage of the threshold signal is held by a sample hold circuit. Therefore, when effective data is received after the synchronizing data, the voltage of the threshold signal is constant. The comparator compares the voltage of the input signal with the voltage of the threshold signal used as a reference. Based on a result of this comparison, a digital signal is reproduced from the input signal. Even when data such as image data containing data in which &#x201c;0&#x201d; is continued for a long time period is received, erroneous detection does not occur, and the transmission speed can be made higher.

It is intended to provide an image forming apparatus and image forming method capable of obtaining a comparatively high-quality image output even under a correction mode that gives preference to processing time required for correction, and capable of suppressing interruption of image formation to the utmost under operational condition such that internal temperature changes continuously. There are saved last five detections of positional shift quantity under first correction mode that gives preference to correction accuracy for each temperature band. Under second correction mode that gives preference to processing time required for correction, there is calculated a difference of a value actually obtained through measurement and an average value of data history belonging to a target temperature band (#7 through #9). Furthermore, the difference is multiplied by a reliability coefficient of main scanning direction and that of sub scanning direction, respectively, to determine correction quantity (#10, #11). Thereby, excessive change of correction quantity is prevented.

In a circuit board comprising multiple layers and having an integrated circuit mounted on the outer layer thereof, a main power supply plane and a sub-power supply plane, which is disposed in an island fashion with a clearance that terminates electric connection with the main power supply plane, are formed on the same layer. The main power supply plane and the sub-power supply plane are connected by first power supply patterns that are formed on a layer different from the layer on which the power supply planes are formed and to which bypass condensers are connected. Power supply to some power supply terminals is achieved via second power supply patterns that are connected to the sub-power supply plane. The leakage of noise from the power supply terminals connected to the second power supply patterns is controlled by the first power supply patterns. Through this construction, the EMI noise radiated from the circuit board can be reduced while minimizing the number of bypass condensers.
