A terminal device includes a screen where information is displayed, an operation range configured to fully or partially cover an operation portion disposed on a back side of the screen, an operation being input from a user to the operation range, and a processor configured to convert a signal obtained from the operation input to the operation range, into a signal indicating coordinate information in an operational range of the screen, wherein the operation range is smaller in size than the operational range of the screen.

Terminal device with back side operation features

A transmission control unit transmits function specifying information for specifying a function to be executed. A function control unit executes a first function specified by the function specifying information. A connecting unit, when an additional function control unit that executes a second function specified according to the function specifying information is connected between the transmission control unit and the function control unit, transmits the function specifying information to the additional function control unit, and when it is disconnected, transmits the function specifying information to the function control unit.

Function control apparatus and function control method

An image forming apparatus includes an image forming unit for forming an image; a status conversion unit for converting the multi-value pixel data into status values; plural reference look-up tables each indicating an association between an arrangement of the status values of a target pixel and adjacent pixels in a pixel window and an output data value of the multi-value pixel data to be output; a determining unit for determining a target reference look-up table based on the arrangement; and a generating unit configured to change an input data value of the multi-value pixel data, into the output data value of the determined target reference look-up table, and for outputting the multi-value pixel data to the image forming unit.

An image processing apparatus includes an address specifying unit, a reading unit, a writing unit, and a shifting unit. The address specifying unit specifies an address in a storage device that stores therein pixel data of an image. The reading unit reads the pixel data from the address by a line pixel amount. The writing unit writes the pixel data in an output storage unit. The shifting unit shifts the address in either one of a first direction along a sub-scanning direction and a second direction opposite to the first direction by a predetermined amount.

Apparatus, method, and computer program product for processing image

An image processing controller performs transmission and processing of image data by connecting an engine and a CPU connected via a chipset. A first controller controls communication with the chipset via a first PCI-Express I/F. A second controller controls communication with the engine when it is connected via a second PCI-Express I/F. A third controller controls communication with the engine when it is connected via a PCI I/F. The first controller receives, on behalf of the engine, an access from the CPU to the engine and inhibits a reference by the CPU to a resource connected to the image processing controller.

The debug controller makes an efficient use of memory in tracing the direct memory access by the processor and the direct memory access controller for the purpose of debugging. The direct memory access for read and write is efficiently traced by first writing a next access memory address at a currently accessing memory address.
