[Embodiment]
FIG. 1 is a diagram illustrating an example of a functional configuration of an image forming apparatus 1 according to the present embodiment. The image forming apparatus 1 in FIG. 1 includes a control unit 10, an image output unit 20, an image input unit 30, a size acquisition unit 31, a color information acquisition unit 32, and an operation unit 80.

  The operation unit 80 inputs an instruction to the image forming apparatus 1 by the operator, and displays information related to the image forming apparatus 1 to the operator. The operation unit 80 includes an input unit 81 and a display unit 82.

  The input unit 81 inputs an instruction to the image forming apparatus 1, conditions set for the job, and the like by the operator. The input means 81 is, for example, a numeric keypad. The display unit 82 displays information regarding the state of the image forming apparatus 1 and the job executed by the image forming apparatus 1. The display means 82 also displays a screen that prompts the operator to input instructions, conditions, and the like. The operation unit 80 may be a touch panel, for example.

  The control unit 10 controls each unit of the image forming apparatus 1. The control unit 10 includes a condition acquisition unit 11, a condition setting unit 12, and a screen generation unit 13. The condition acquisition unit 11 acquires an output condition when the image output unit 20 outputs an image. The output condition is, for example, the size of the medium on which an image is formed. The output condition may also be, for example, the size of the output image. The output condition may also be information on whether an image is output in color or monochrome. This information is called “color information”. The color information may be information on the number of colors of toner forming the image.

  The condition setting unit 12 sets an input condition based on the output condition acquired by the condition acquisition unit 11. The input condition is a condition when the image input unit 30 acquires image data. The input condition is, for example, the size of the image or medium corresponding to the image data. This size is called the input image size. The input condition may also be color information.

  For example, when the medium size included in the output condition is only one medium size, the condition setting unit 12 sets the medium size as the input image size. For example, when the medium size included in the output condition is a plurality of medium sizes, the condition setting unit 12 sets the input image size of the input condition to “automatic size detection”.

  For example, when the color information included in the output condition is “color”, the condition setting unit 12 sets the color information of the input condition to “color” and the color information included in the output condition is “monochrome”. In this case, the color information of the input condition is “monochrome”. When the color information included in the output condition is “color”, the color information of the input condition may be “automatic color detection”. This is because, for example, when the image output means is a plotter, the forming means for forming a color image usually forms a monochrome image.

  The screen generation unit 13 generates a screen to be displayed on the operation unit 80. For example, the screen generation unit 13 generates a screen that prompts the user to input conditions set when the image input unit 30 reads an image on a document. The screen generation unit 13 may also generate a screen that prompts the user to input conditions set when the image output unit 20 outputs an image.

  The image output means 20 performs an output process on the image data and outputs an image. For example, in the case of a plotter, the image output means 20 performs processing for print output, and forms and outputs the image data on a medium. The output conditions when the image output unit 20 performs print output are, for example, the size of the medium on which the image is formed, the number of toner colors when forming the image, and the like. The output condition may further include information such as the number of copies to be output and the enlargement / reduction of the image. The image output means 20 includes, for example, a plotter device and a control unit that controls the plotter device. The image output means 20 may be a facsimile, a means for outputting image data by network communication, or a means for storing image data in a storage means such as a hard disk device.

  The image input means 30 acquires input image data to be input. For example, in the case of a scanner, the image input unit 30 optically reads an image formed on a document and generates image data. The image input means 30 further performs predetermined image processing on the optically read signal. This image processing is, for example, color correction. The image input unit 30 includes, for example, a scanner device and a control unit that controls the scanner device.

  The image input unit 30 may be any unit that sets the size of input image data to be input according to input conditions and acquires the input image data.

  The size acquisition unit 31 acquires an image size when the image input unit 30 acquires input image data. The image size is the size of the medium on which the image is formed or the size of the image itself. When the image input unit 30 is a scanner, the size acquisition unit 31 acquires a document size when reading an image on the document.

  The color information acquisition unit 32 acquires color information when the image input unit 30 acquires input image data. When the image input unit 30 is a scanner, the color information acquisition unit 32 acquires color information when reading an image on a document.

  In the following FIGS. 2 to 6, an example in which the input of an image is reading by a scanner and the output of an image is a print output will be described.

In FIG. 4, “no size restriction” is included in one of the plurality of paper sizes. In FIG. 4, automatic size detection is set from the operation unit 800 to the image input unit 310. On the other hand, the output paper size is designated from the operation unit 800 to the image output unit 210. Here, A4 size is designated. Thereby, the size information including the value of “A4 size” is notified from the image output unit 210 to the image input unit 310.

  Also, the output paper size is designated from the operation unit 800 to the image output unit 220. Here, “no size designation” is designated. As a result, the image output unit 220 notifies the image input unit 310 of size information including a value of “no size restriction”.

  The image input unit 310 sets input conditions for the image input device 320 based on the input from the operation unit 800, the input from the image output unit 210, and the input from the image output unit 220. Here, “automatic size reading” is designated in order to correspond to different size information from the two image output units. The image input device 320 reads an image on a document by automatic size reading.
