    摘要: Procédé d'analyse et/ou de restitution de documents selon lequel on traite par des moyens d'analyse ou de restitution plusieurs lignes à la fois, dans un seul balayage suivant une direction X, et, après ce balayage, une transla tion relative est effectée entre le document et les moyens d'analyse ou de restitution suivant une direction Y transver sale à la direction X, puis un nouveau balayage de plusieurs lignes suivantes a lieu et ainsi de suite, ce procédé étant prévu pour analyser ou restituer p points suivant chaque ligne.
    On effectue chaque balayage suivant une largeur de nk lignes; à chaque balayage on traite p/k points par ligne; la translation suivant la direction Y, entre deux balayages successifs, a une amplitude correspondant à n lignes et, à chaque balayage, on traite des points qui sont décalés par rapport aux points du balayage précédent d'une distance i/k suivant la direction X, i étant la distance qui sépare deux points successifs d'une ligne divisée en p/k points.

    摘要: P (fifteen) recording heads are arranged in two columns in a zigzag pattern in a recording unit. The P recording heads are divided into N (two) groups in the sub-scanning direction (up-down direction in the figure). The N (two) controllers respectively control the recording heads pertaining to corresponding groups. When it is determined that the variable data straddles a boundary (M/S boundary line) of recording regions (a master recording region and a slave recording region) of the recording heads, which are controlled by different controllers, the linefeed width of the recording unit is adjusted to a linefeed width where all the variable data do not straddle the M/S boundary line.

    摘要: An image forming apparatus includes a recording head including a plurality of printing elements each of which offsets at least in an auxiliary-scanning direction one another and ejects droplets toward a recording medium. The image forming apparatus further includes a main scanning unit configured to scan the recording head, relative to the recording medium, in a main scanning direction perpendicular to the auxiliary-scanning direction. The image forming apparatus still further includes a auxiliary-scanning unit configured to scan the recording head, relative to the recording medium, in a main scanning direction perpendicular to the auxiliary-scanning direction. The image forming apparatus still yet further includes a controller configured to control the printing head, the main scanning unit and the auxiliary-scanning unit to form dots in rows arranged in the auxiliary-scanning direction at a first predetermined interval, and columns arranged in the main scanning direction at a second predetermined interval while performing main scans and sub-scans repeatedly. The controller controls the printing head, the main scanning unit and the auxiliary-scanning unit to form first dots in an area of the printing medium at first alternate columns by a first main scan, and to form second dots in the area by a second main scan at second alternate columns different from the first alternate columns. The second dots are shifted, relative to the first dots, a first predetermined distance smaller the first predetermined interval.

    摘要: In order to record information on a recording substrate (2), a printing head (1) with a number (a) of printing elements (11) is moved to and fro across printing positions (22, 23, 24) by lines. Partial numbers (n) of the printing elements (11) form sub-groups (15) in accordance with a predetermined individual print line which are allocated to the printing positions (22, 23, 24) of a printed line (29) and formed by at least partly differing printing elements (11). The printing elements (11-1 to 11-4) of the sub-group (15) concerned are selectively controlled at the printing positions (22, 23, 24) in accordance with the printing data to produce a model print line (31). On the completion of a subsequent model print line (33), the formation of a subsequent model print line (34) is determined at least on the continuation side on the formation of the previous print line (29). Stripes caused by line continuation errors or inking ribbon structural errors are distributed with a vertical displacement over the printed image by the process of the invention; unlike the case with uniform structures, the human eye hardly takes notice of such distributed faults.

    摘要: A computerised methodology for reducing swath scanner swath boundary discontinuities is provided by using a predetermined overlap of pixel row during each sequential scan. Pixel data from a first scan (400-401) of the overlapped pixel rows is compared to the pixel data from a second scan (405, 409, 411, 415, 417) of the overlapped pixel rows, identical pixels of the overlapped pixel rows ideally having the same representative scan data. Errors are compensated by weighting representative scan data for each pixel row, linearly decreasing the weighting in proportion to the proximity to the swath boundary (413). Weighted data is substituted for true data depending upon comparison factors (403, 407). In one embodiment, the weighting factor is an increase or decrease in the first scan data relative to the percentage change in white level intensity captured in the second scan of the overlapped pixel rows. In another embodiment, the weighting factor is a linear shifting of the proportion of the pixel data from the first scan and the pixel data from the second scan of the overlapped pixel rows used as the scanned image data such that the proportion of the first scan decreases as the proportion of the second scan increases, thereby smoothing differentials in data representative of individual pixel rows at swath boundaries. In another embodiment, scanner signal-to-noise ratio is improved by using a weighting factor in accordance with the Central Limit Theorem.

    摘要: An image pickup device includes a split member (2) for splitting image pickup light from an object into a plurality of beams (L1,L2) in equal light amounts and forming object images at different positions. A plurality of image sensors (101-104) are provided, light-receiving portions (a1,a2,b1,b2) of which are arranged at split positions which are not adjacent to each other when an object image is split into a plurality of image portions on each image formation plane (A,B). An image synthesizing circuit (3) receives information from the image pickup elements and synthesizes the output object image. The image sensors are controlled by a timing signal from a single clock generation circuit.
