Abstract

An image reading device includes an imaging device to capture an image of a document placed below the imaging device to generate a document image and output an image signal based on the document image, circuitry to determine a size of a fed-sheet based on information on the fed-sheet, the fed-sheet being a sheet to be formed with the document image, generate a frame image for the document image, the frame image having a size equal to the size of the fed-sheet, and synthesize the frame image with the image signal output from the imaging device to generate a synthesized image, and a display to display the synthesized image.

Claims

1. An image reading device comprising:

an imaging device configured to capture an image of a document placed below the imaging device to generate a document image and output an image signal based on the document image;

circuitry configured to

determine a size of a fed-sheet based on information on the fed-sheet, the fed-sheet being a sheet to be formed with the document image,

generate a frame image for the document image, the frame image having a size equal to the size of the fed-sheet, and

synthesize the frame image with the image signal output from the imaging device to generate a synthesized image; and

a display to display the synthesized image.

2. The image reading device of claim 1 wherein, the circuitry is further configured to

determine an orientation of the fed-sheet based on the information on the fed-sheet, and

change display information on the frame image according to the orientation of the fed-sheet.

3. The image reading device of claim 1 wherein the circuitry is further configured to:

detect a set position of the document image with respect to the frame image, and

when the document image is set within the frame image, change display information on the frame image to indicate that the document is set within the fed-sheet.

4. The image reading device of claim 3 wherein, when the document image is not set within the frame image, the circuitry adds instruction information to the display information on the frame image, the instruction information instructing to reset the document in a correct position.

5. The image reading device of claim 3 wherein a number of detection operations of detecting the set position of the document, performed by the circuitry, is less than a number of input operations of capturing the image of the document, performed by the imaging device.

6. The image reading device of claim 1 wherein, the imaging device captures, as the image of the document, a moving image of the document with a resolution lower than a resolution used when scanning the document in response to a user instruction.

7. An image forming apparatus comprising:

the image reading device of claim 1; and

an image forming device to form an image on the fed-sheet based on the document image.

8. The image forming apparatus of claim 7, further comprising circuitry configured to:

receive a user selection of a size of a print sheet to be used for printing the document;

detect a size and an orientation of the fed-sheet set on a sheet-feeding tray;

generate the information on the fed-sheet based on the size of the print sheet for the document and the size and the orientation of the fed-sheet; and

output the information on the fed-sheet to the image reading device.

9. A method of displaying a document image, the method comprising:

capturing, with an imaging device, an image of a document placed below the imaging device to generate a document image and output an image signal based on the document image;

determine a size of a fed-sheet based on information on the fed-sheet, the fed-sheet being a sheet to be formed with the document image;

generating a frame image for the document image, the frame image having a size equal to the size of the fed-sheet;

synthesizing the frame image with the image signal output from the imaging device to generate a synthesized image; and

displaying the synthesized image on a display.

10. A non-transitory recording medium storing a plurality of instructions which, when executed by one or more processors to perform a method of displaying a document image, the method comprising:

capturing, with an imaging device, an image of a document placed below the imaging device to generate a document image and output an image signal based on the document image;

determine a size of a fed-sheet based on information on the fed-sheet, the fed-sheet being a sheet to be formed with the document image;

generating a frame image for the document image, the frame image having a size equal to the size of the fed-sheet;

synthesizing the frame image with the image signal output from the imaging device to generate a synthesized image; and

displaying the synthesized image on a display.
