An autonomously traveling cart system includes a mover, a memory, a position detector, and a processor. The mover moves a cart main body. The memory stores map data indicating an autonomously traveling cart storage space installed in an area where the cart main body is movable. The position detector detects a position of the cart main body. The processor designs a moving route from the position of the cart main body which the position detector detects toward the autonomously traveling cart storage space indicated by the map data, and allows the cart main body to move toward the autonomously traveling cart storage space by the mover.

A multi-function image processing apparatus includes a system control unit that receives an image processing job sent over a network by a requesting device, and that controls operation of the image processing apparatus. The apparatus includes an image recording unit that performs a printing operation. The apparatus also includes a scanner that scans data provided to the apparatus. The apparatus further includes an image processing unit that receives scan data from the scanner, that performs image processing on the scan data, and that outputs image-processed scan data to the image recording unit for printing of the image-processed scan data. The apparatus also includes an interface unit that transfers image data between the image processing unit and the system control unit in at least one mode of operation of the image processing apparatus. The image processing unit includes a first FIFO and a second FIFO for bypassing the interface unit under certain situations.

A system and method for reproducing original documents includes scanning an original document to generate image data corresponding to the scanned original document, dividing the image data into a plurality of image data blocks, and compressing the plurality of image data blocks into respective compressed image data blocks, such that data of each compressed image data block is independent of data of each other compressed image data block. Each compressed image data block is stored in a first memory with a respective predetermined beginning address. The first compressed image data block, having a first predetermined beginning address, is accessed from the first memory and decompressed into a first decompressed image data block. At least one image processing function is performed on the decompressed first image data block.

An image forming apparatus includes a four line CCD which produces RGB data and K data that are read out selectably, and a selector which selects whether to output the RGB data that is provided from the four line CCD. The image forming apparatus also includes a storage part which stores a plurality of patterns, and a judgment part that produces a judgment signal based on a comparison of the RGB data and the plurality of patterns stored in the storage part.

In an image processing apparatus, such as a digital color/monochromatic copying machine, for reading a color image or a monochromatic image and producing a copy image thereof, an image process section is composed of an arithmetic section which is programmed and operated by software, or image process programs. The image process programs are input from outside via an external interface and loaded in an external RAM. On the basis of input information from an operation panel, an optimal image process program is read out of the external RAM and loaded in an instruction RAM. The arithmetic section executes the image process program in the instruction RAM.

A system and method for adjusting the color of a scanned image includes obtaining image data for the scanned image, generating an output image from the scanned image, and obtaining image data for the output image. The differences between the image data of the scanned image and the image data of the output image are determined, coefficients are generated from the determined differences. The image data of the scanned image is then adjusted based on the generated coefficients.

Without repeating compression/decompression operations, an editing process such as rotation can be executed using first compression data, and second compression data, whose compression ratio is increased, can be stored in a hard disk drive.

Image processing apparatus

An image processing apparatus and an image processing method of the present invention improves image quality during monochrome output by adaptively executional conversion from a color image signal to a monochrome image signal during monochrome image output, and by using outputs from color and monochrome sensors at the same time. Moreover, it lowers the cost of compressing a color signal by using a color sensor with a lower resolution than that of the monochrome sensor.

Image processing apparatus and image processing method

An image producing section produces a character or pattern image indicative of the input conditions of a color scanner section. The input conditions include data on the resolution, the sampling rate, etc. An image synthesis section synthesizes the produced image with an image scanned by the color scanner section and subjected to predetermined image processing. The resultant synthesized image is printed out by a color printer section. The operating conditions, such as the image input conditions, are clear from the character or pattern image printed out as part of the synthesized image.

A lower-bit replacement means of an information addition means replaces lower 3 bits of an 8-bit image signal with 3 bits of an image area separation signal, and outputs an 8-bit conversion image signal. A lower-bit extraction means of an information extraction means extracts lower 3 bits of the-bit conversion image signal and outputs an image area separation signal as additional information. On the other hand, as regards image information, the conversion image signal input to the information extraction means is output as it is, as an image signal.

By using the memory which stores the first lattice point color coordinates data equivalent to the lattice point address of the color conversion LUT data which is referred to at the time of color conversion processing, the color adjustment parameter composition section which composes the color adjustment parameter in accordance with the instruction information of the input color adjustments, and the color adjustment section which outputs the second lattice point coordinates data by conducting color adjustment on the first lattice point color coordinates stored in the memory by using this color adjustment parameter, and after converting the second lattice point color coordinates data to the second lattice point color coordinates data expressed in the second color space, conduct conversion processing on the input image data expressed in the first/color space in accordance with the color conversion LUT data which is renewed by this. It is a color image processing apparatus that possesses at least a color conversion section which outputs the output image data expressed in the second color space. By doing so, color conversion processing only for the color adjustment processing becomes unnecessary. Thus, it is possible to provide an image processing apparatus that can conduct color conversion processing with rapid color adjustment.
