摘要： An image processing device determines whether or not a data size per page of a received print job is greater than a preset threshold. When it is determined that the data size is greater than the threshold, the image processing device estimates a first RIP time per page, which is the time required to RIP process when a resolution of an image of the print job is not optimized, an optimization time per page, which is the time required to optimize, and a second RIP time per page when the resolution of the image of the print job is optimized. Then, the image processing device optimizes the resolution of the image of the print job on the basis of the first RIP time, the optimization time, and the second RIP time so that the rates of decreasing the resolution in each image after conversion are substantially the same.

摘要： A density corrector performs a density correction processing on a resolution-converted image dataset to obtain a density-corrected image dataset by: determining whether each of first and second pixels in the resolution-converted image dataset is a deletion-target pixel, the first pixels each being a pixel located at a position including a longitudinal edge in a second original image, the second pixels each being a pixel located at a position including a lateral edge in the second original image, patterns of edges in regions in the first and second original images corresponding to the deletion-target pixel being the same; correcting a density of the deletion-target pixel to “0”; and correcting a density of respective pixels other than the deletion-target pixel among the first and second pixels to a value equal to or larger than an original density of the respective pixels.
