An information processing apparatus includes: a first receiving unit that receives a radio signal through a first wireless communication channel; a second receiving unit that receives a radio signal through a second wireless communication channel in which position measurement accuracy and radio wave reachable range are higher and shorter respectively than those in the first wireless communication channel; a calculation unit that calculates information on position of the information processing apparatus by using field intensity of the radio signal received by the first or second receiving unit; a transmission unit that transmits the calculated position information; and a control unit that causes the calculation unit to calculate the information, and, when a preset condition is satisfied, performs switching control to cause the calculation unit to calculate the information on the position of the information processing apparatus based on the radio signal received by the second receiving unit.

An integrated circuit includes a first signal line, a first circuit, a second signal line, and an attaching circuit. A first signal is transferred via the first signal line. The first circuit is connected to the first signal line and performs image processing upon the first signal being transferred thereto. The second signal line is connected to the first signal line, and a second signal indicating that the first signal has been transferred is transferred via the second signal line. The attaching circuit is connected to the second signal line and attaches, upon the second signal being transferred thereto via the second signal line, information corresponding to the second signal to an image resulting from the image processing performed by the first circuit.

Integrated circuit, image processing apparatus, and image processing method

An image processing apparatus includes multiple image processing units and multiple execution controllers. The multiple image processing units respectively perform different types of image processing operations executable on image data. The multiple execution controllers each perform control to select and run grouped image processing units of the multiple image processing units. Each of the multiple execution controllers selects and runs the grouped image processing units in accordance with a corresponding one of rules that are specified for the respective execution controllers, and one of the multiple execution controllers is used in a series of image processing operations performed on the image data.

Image processing apparatus and image forming apparatus

An image processing apparatus has an image input section, a color image processor, a monochrome image processor and an image synthesizer. The image input section inputs image data of an original image. The color image processor generates color image data by performing color image processing on the image data. The monochrome image processor generates monochrome image data by performing monochrome image processing on the image data. The image synthesizer generates synthesized image data by synthesizing the monochrome image data with the color image data. The apparatus also has a buffer that temporarily stores image data, a determination section that determines on the basis of the image data of the original image whether the original image is color or monochrome, and an output controller that controls an image output process. The output controller outputs output color or monochrome image data fetched from the buffer as determined to be appropriate.

Image processing apparatus

An image processing apparatus which performs a rotating process at a specified angle on the image data entered into it and forms image data as processed for rotation thereof on a page memory device. In the image processing apparatus, it is possible to perform a rotating process at a specified angle on the image data which are different in the number of bits per one pixel, using the same device, by performing the processing operations in the writing/reading address generating units and by controlling the changeover of the operations by the image data synthesizing unit, in accordance with a preset value indicating the image structure information in the image data entered into the image processing apparatus. Above all, it is possible for the image processing apparatus efficiently to perform the processes for rotating the image data by 0 degree, 90 degrees, 180 degrees, and 270 degrees.

An image processing system including a reconfiguration circuit, typically responding to fault detection. The image processing includes a data compressing unit for compressing image data generated by an image input terminal, a data storage unit for storing output compressed image data, a data decompressing unit for decompressing compressed data and for transferring the decompressed data to an output terminal. A control unit controls the system to compress and store image data, and then to repeatedly read out and transfer the stored data to the image output terminal. When a self diagnosis detects a fault in any one of the compressing unit, data storage unit, or data decompressing unit, the faulty unit is bypassed with a special data bus, thereby allowing system operating to continue.

A method of diagnosing the operating conditions of an image processor comprising the steps of preparing a first pattern of data, a second pattern corresponding to the first pattern when it has been compressed normally, a third pattern of data, and a fourth pattern corresponding to the third pattern when it has been expanded normally; diagnosing an operating condition of the compressor by comparing data after the first pattern has been compressed by the compressor with the second pattern; and diagnosing an operating condition of the expander by comparing data obtained after the third pattern has been expanded by the expander with the fourth pattern. The independent diagnosis of the compressor and the expander allows the specific defective chip of component to be identified, thereby facilitating proper repair.
