Abstract
An image forming apparatus includes a receiving part that receives multiple page images including a first page image and a second page image, a medium carrying part that carries the recording media, and an image forming part that forms images on the recording media carried by the medium carrying part based on the first and second page images processed by the image processing part. The image processing part determines one edge region of the first page image, which has the highest image density among four edge regions on the first page image, changes the orientation of the first page image such that the one edge region having the highest image density is arranged to be at the trailing side of the first page image, and changes the orientation of the second page image to the same orientation as that of the first page image.
Claims14
An image forming apparatus, comprising:
- a receiving part that receives multiple page images including a first page image and a second page image, which either leads or follows the first page image, from an external device, each of the first and second page images being to be formed on one of recording media wherein the first and second page images are in a rectangular shape with four sides surrounding their boundaries and each have orientations that coincides with a carrying direction of the recording media, and in accordance with the orientations, one leading side, one trailing side and two lateral sides, which are positioned between the leading side and the trailing side, are defined from the four sides of the first and second page images,
- an image processing part that
- calculates image densities of four edge regions that correspond to the four sides of the first page image so as to obtain a calculation result, and
- changes the orientations of the first and second page images based on the calculation result,
- a medium carrying part that carries the recording media, and
- an image forming part that forms images on the recording media carried by the medium carrying part based on the first and second page images processed by the image processing part, wherein
- the image processing part
- determines one edge region of the first page image, which has the highest image density among the four edge regions on the first page image,
- changes the orientation of the first page image such that the one edge region having the highest image density is arranged to be at the trailing side of the first page image, and
- changes the orientation of the second page image to the same orientation as that of the first page image.
An image forming apparatus, comprising:
- a receiving part that receives multiple page images including a first page image and a second page image, which either leads or follows the first page image, from an external device, each of the first and second page images being to be formed on one of recording media wherein the first and second page images are in a rectangular shape with four sides surrounding their boundaries and each have orientations that coincides with a carrying direction of the recording media, and in accordance with the orientations, one leading side, one trailing side and two lateral sides, which are positioned between the leading side and the trailing side, are defined from the four sides of the first and second page images,
- an image processing part that
- calculates margin widths of four edge regions that correspond to the four sides of the first page image so as to obtain a calculation result, and
- changes the orientations of the first and second page images based on the calculation result,
- a medium carrying part that carries the recording media, and
- an image forming part that forms images on the recording media carried by the medium carrying part based on the first and second page images processed by the image processing part, wherein
- the image processing part
- determines one edge region of the first page image, which has the narrowest margin width among the four edge regions on the first page image,
- changes the orientation of the first page image such that the one edge region having the narrowest margin width is arranged to be at the trailing side of the first page image, and
- changes the orientation of the second page image to the same orientation as that of the first page image.
