Abstract
An image processing apparatus reads an image of an original line by line and to inputs the read image signal line by line and stores the input image signal in a memory controller changes the read-out position of the image signal from the memory, for read-out line by line or on in units of a few lines. A setting circuit sets an amount of slant of an image to be output, for image formation circuit on a selected recording material. The controller controls the reading position of the image signal of the memory in accordance with the set slant amount. With this image processing apparatus, the original image can be easily modified, shifted, and rotated and also recorded on a recording sheet line by line or in units of a few lines by simple operations.
Claims21
An image processing apparatus comprising:
- input means for inputting image signals representing an original image on a line by line basis;
- memory means for storing the image signals entered from said input means on a line unit basis, said memory means being such as to permit the image signals stored in said memory means to be read out from an arbitrary memory location on a line unit basis;
- image forming means for forming an image on a recording material on a line by line basis based on the image signals read out from said memory means on a line unit basis;
- setting means for setting a slant amount of an image to be formed, relative to the original image;
- and
- control means for changing a read-out start position of the image signals from said memory means each n lines, where n is a predetermined number, in accordance with the slant amount set by said setting means.
An image processing apparatus comprising:
- input means for inputting image signals representing an original image on a line by line basis;
- memory means for storing the image signals entered from said input means on a line unit basis, said memory means being such as to permit the image signals stored in said memory means to be read out therefrom in an arbitrary timing on a line unit basis;
- image forming means for forming an image on a recording material on a line by line basis based on the image signals readd out from said memory means on a line unit basis;
- setting means for setting a slant amount of an image to be formed, relative to the original image;
- and
- control means for changing a read-out start timing of the image signals from said memory means each n lines, where n is a predetermined number, in accordance with the slant amount set by said setting means.

- image forming means for forming an image on a recording material on a line by line basis based on the image signals read out from said memory means on a line unit basis;
- control means for changing a read-out start position or timing of image signals from said memory means each n lines, where n is a predetermined number of lines;
- and
- determining means for determining a size of the recording material, on which the image is to be formed, in accordance with a condition of the image formed by said image forming means.
