Abstract:
1. A recording control system controlling an inkjet recording operation for recording an image by controlling a recording head based on image data indicating the image, the recording head having a plurality of nozzle rows and being configured to be capable of scanning in a first direction and a second direction opposite to the first direction, the plurality of nozzle rows corresponding to a plurality of colors, each nozzle row including a plurality of nozzles that are arranged in a direction intersecting with the first and second directions and that are configured to eject ink of corresponding color, the image including a plurality of pixels, the image data having a plurality of sets of pixel data corresponding to the plurality of pixels, each set of pixel data including a pixel value representing color of a corresponding pixel and indicating an amount of ink of the color, the recording control system comprising: a setting unit that sets, in the image, a first region and a second region adjacent to the first region and that sets a detection region in one of the first and second regions, a selecting unit that selects at least one pixel from among the pixels in the detection region such that a number of the selected at least one pixel is smaller than a total number of the pixels existing in the detection region; a determining unit that determines whether a pixel value of the selected at least one pixel satisfies a criterion; a control unit that controls the recording head to eject ink based on pixel data corresponding to pixels in the first region while controlling the recording head to scan in the first direction such that the recording head records the image in the first region, the control unit controlling the recording head to eject ink based on pixel data corresponding to pixels in the second region while controlling the recording head to scan in the first direction such that the recording head records the image in the second region when the determining unit determines that the pixel value of the selected at least one pixel satisfies the criterion, the control unit controlling the recording head to eject ink based on pixel data corresponding to pixels in the second region while controlling the recording head to scan in the second direction such that the recording head records the image in the second region when the determining unit determines that the pixel value of the selected at least one pixel does not satisfy the criterion; and an accumulating unit that obtains an accumulation value by accumulating the pixel value for the selected at least one pixel, wherein the determining unit determines that the pixel value of the selected at least one pixel satisfies the criterion when the accumulation value is greater than or equal to a predetermined value, and wherein the determining unit determines that the pixel value of the selected at least one pixel fails to satisfy the criterion when the accumulation value is smaller than the predetermined value.
