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; and
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.
2. The recording control system according to claim 1, wherein the setting unit sets a plurality of representative pixels in the detection region, the plurality of the representative pixels being a part of the pixels in the detection region, a number of the plurality of the representative pixels being smaller than a total number of the pixels existing in the detection regions,
wherein the selecting unit selects the at least one pixel from among the plurality of representative pixels.
3. The recording control system according to claim 2, wherein the plurality of pixels are arranged in the image in an x direction and a y direction, the position of each pixel being defined by an x coordinate value with respect to the x direction and a y coordinate value with respect to the y direction,
wherein the setting unit sets the detection region such that the x coordinate values and the y coordinate values of all the pixels in the detection region are in an x detection range and in a y detection range, respectively, and
wherein the setting unit sets the plurality of representative pixels in the detection region such that each x coordinate value in the x direction range is equal to the x coordinate value defining the position of at least one representative pixel and each y coordinate value in the y direction range is equal to the y coordinate value defining the position of at least one representative pixel.
4. The recording control system according to claim 2, wherein the representative pixels are arranged continuously in the detection region.
5. The recording control system according to claim 2, wherein the detection region is a rectangular shaped region, and
wherein the representative pixels are arranged continuously along a diagonal line defined in the rectangular shaped region.
6. The recording control system according to claim 2, wherein the detection region is a rectangular shaped region,
wherein the representative pixels are arranged continuously along a pair of diagonal lines in the rectangular shaped region.
7. The recording control system according to claim 2, wherein the selecting unit selects all the pixels from among the representative pixels.
8. The recording control system according to claim 1, further comprising an accumulating unit that obtains an accumulation value by accumulating the pixel value for the selected at least one pixel, and
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,
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.
9. The recording control system according to claim 1, wherein the setting unit sets the first region, the second region, and the detection region in the image such that all of the first, second, and detection region have rectangular shapes, one side of the detection region coinciding with a part of a border line between the first region and the second region.
10. The recording control system according to claim 9, wherein the selecting unit selects, among the pixels in the detection region, the at least one selected pixel that is adjacent to the one side of the detection region coinciding with the part of the boarder line.
11. The recording control system according to claim 1, wherein the setting unit sets the first region and the second region such that the first region and the second region are arranged in a direction orthogonal to the first and second directions.
