Objects of the present invention are to facilitate filling out by hand an electronic paper and to realize digitization of contents with which the electronic paper is filled out by hand with a simple structure. A read image is obtained by optically reading a reading-object of the electronic paper. Based on the document information written on the electronic paper and writing-conditions during document writing, which are represented by the document information, a display image of the document in accordance with the read image information is formed. A written image is separated and extracted by converting a density only of pixels among the respective pixels of the read image, whose densities vary in accordance with the document writing and which correspond to a portion, to which ink of a pen for the handwriting is not adhered.

The liquid ejection apparatus comprises: an ejection head having ejection holes which eject liquid droplets to land on an ejection receiving medium; a conveyance device which causes the ejection head and the ejection receiving medium to move relative to each other in one direction, by conveying at least one of the ejection head and the ejection receiving medium in a relative conveyance direction substantially perpendicular to a breadthways direction of the ejection receiving medium; a direction of flight deflecting device which deflects direction of flight of the liquid droplets ejected from the ejection head in a direction which includes at least a component that is substantially parallel to the relative conveyance direction; and a deflection control device which controls the direction of flight deflecting device, wherein when droplets are ejected during relative conveyance of the ejection receiving medium and a row of dots is formed in which dots that are mutually adjacent in the relative conveyance direction are at least partially overlapping with each other, the deflection control device changes landing positions of the liquid droplets by a droplet landing position change amount y which satisfies the following relationship: y=Pts×I, where Pts is a pitch between dots in the row of dots in the relative conveyance direction, I is an amount of shift comprising two or more types of integers of any value, and y is the droplet landing position change amount in the relative conveyance direction, thereby causing the droplets to land while avoiding consecutive landing of mutually adjacent dots.
摘要:
There is disclosed an image synthesizing apparatus for producing a synthetic image that consists of a background image and at least a main image superimposed on the back ground image. An input image is displayed in a main display area of a control screen, whereas an outer frame and at least an inner frame are displayed in a sub display area of the control screen in accordance with a selected template. First a crop boundary having a similar shape to the outer frame is displayed on the image in the main display section. The crop boundary is movable on the image and changeable in size. After pasting a cropped area of the image as the background image in the outer frame, a second image is selected and displayed in the main display area. Then, a crop boundary having a similar shape to the inner frame is displayed on the second image, so a cropped area of the second image is pasted in the inner frame, to be printed as the main image.
