Abstract: A recording device includes an image retrieval unit, a memory, an image forming unit, and a control unit. The image retrieval unit retrieves images of the document pages as document image data. The control unit begins retrieving document image data from the memory as the image retrieval unit is retrieving document image data and sends the document image data to the image forming unit. The image forming unit uses document image data to form images on recording sheets faster than the image data is retrieved. The control unit checks the memory to confirm whether document image data for a next document page is stored in the memory. The timing of the memory check is both after completion of forming an image of a present document page at the recording sheet transport speed and when storage of image data for the next document page is anticipated to start in the memory.

Abstract: A computer/printer system and method which includes and involves a screen-display device with a display screen, and wherein requests for a document print preview results in the direct and accurate creation by the printer per se of a true preview on the display screen showing how the document will actually look after printing.

Abstract: The invention concerns an image recording apparatus suitable for forming a medical image that is used for a medical diagnosis, and a test pattern for evaluating a quality of the medical image. The image recording apparatus includes a printing section to either the medical image or the test pattern on the recording medium, based on image date; a printing-condition setting section to set a printing condition for printing the test pattern; and a printing-condition displaying section to display the printing condition set by the printing-condition setting section. The printing section prints at least one of a sharpness-evaluating pattern and a granularity-evaluating pattern.

Abstract: An image signal with an overshoot is generated on a positive-going edge of an input image signal with an overshoot producing unit. Then, a light signal with an overshoot is outputted from a recording light source in response to the image signal with the overshoot supplied from the overshoot producing unit. The light signal outputted from the recording light source is applied to scan a photosensitive medium to record an area gradation image on the photosensitive medium.

Abstract: Conversion of color data values from a rectangular coordinate system such as CIELab to a cylindrical coordinate system such as CIELCh using two one-dimensional look-up tables, one each for the C value and the h value. The one-dimensional look-up tables are accessed by defining a new variable ? as the absolute value of the ratio of b and a.

Abstract: In an external print controller added to an MFP, bit map data obtained by analyzing and developing received PDL data is once compressed and, subsequently, transferred via a PCI bus. In the compressed bit map data, the data in a compressed state is stored onto an HD in the MFP as it is. The compressed bit map data is read out from the HD, decompressed, and sent to a printer unit.

Abstract: The present invention provides a self-propelled image read module, which comprises a sensor, a guide rod, a motor, a gear set, and a belt. The guide rod is fixed on a base of a scanner. The sensor is slidably matched on the guide rod. The motor is disposed at one side of the sensor. The gear set is connected to the motor. The belt is fixed on the base. The belt passes through between and contacts a transmission wheel and an idle wheel of the gear set. Thereby, a scanner's image read module of simple assembly, low cost, and small size is formed.

Abstract: A printing apparatus using a network which is used in a network environment in which a plurality of computer devices and a plurality of network printing apparatuses are connected to a network spools printing jobs received from the computer devices, displays information of the printing jobs and information of the other network printing apparatuses for a user, and transfers the specified printing job to the specified network printing apparatus when the user specifies the printing job and the network printing apparatus.

Abstract: An image forming system, having: a first controller that controls whether to make the first image processor to process image data in accordance with the function selected by the function selector, or to make the written data transmitter to transmit data by transmitting image data to the second image processor with the read data transmitter and by processing image data with the second image processor; a job register that registers plural jobs; a priority order determiner that determines the priority order for output of jobs registered by the job register, and a second controller that determines the outputting order for image data of each job based on the priority order and outputs image data of the job whose priority order is highest among jobs which are capable of immediate output when image data of a job is impossible to be outputted because of a process by the second image processor.

Abstract: In ink-jet printing apparatuses having a monochrome head which is longer than a color head, if a monochrome image is processed as a color image, the printing speed cannot be improved. Accordingly, the color attribute is determined by pixel based on a luminance signal indicating a color multivalue image, and the number of color attributes and the number of array attributes in a first line group are counted. Based on these count values, a parameter indicating an image characteristic of second line group including the first line group is calculated. The image attribute of the second line group is determined in correspondence with the respective count values and the parameter. Then, based on the results of determination about adjacent second line groups, the image attribute of third line group included in the second line groups is determined. Thus attribute determination can be appropriately performed in predetermined band units of image data.

Abstract: An active matrix display device comprises an array of picture elements, e.g. liquid crystal picture elements, first and second sets of address conductors (16, 18) extending in row and column directions respectively and connected with the picture elements, and a set of connection conductor lines (30?) extending in the same direction as one set of address conductors (18), each of which is connected to a respective one of the other set of conductors (16), and via which address signals are supplied to that other set. To avoid unwanted display artefacts, each connection conductor line (30?) extends from one side of the array and terminates adjacent its connection point (32) to its associated address conductor (16) and a respective complementary conductor line (30?) is provided which extends from close to the connection point (32) to the opposite side of the array, the complementary conductor line being electrically separate from the connection line (30?) and coupled to reference signal supply (40).
