Conventionally, in a case of carrying out scanning processing using an image reading apparatus, a user executes the scanning processing according to a desired scan setting. Further, in the scanning processing, there is scan setting recommended depending on the image to be scanned. However, there is a problem that the scan setting operation is troublesome and it is difficult for the user to carry out optimized scan setting.
In accordance with one embodiment, an image processing apparatus comprises a target data acquisition section, an identifier information acquisition section and an image forming section. The target data acquisition section acquires image data which is to be printed on a sheet. The identifier information acquisition section acquires identifier information indicating an identifier which is to be printed on the sheet together with the image data and is used for specifying the handling of scanning data acquired when scanning the sheet printed with the identifier. The image forming section forms, when forming an image based on the image data acquired by the target data acquisition section on a sheet, an image indicating the identifier information acquired by the identifier information acquisition section together with the image data on the sheet.
In the present embodiment, the image processing apparatus forms an image on a sheet and meanwhile prints an identifier on the sheet. The identifier is, for example, a QR code, and is capable of containing information of scan setting. In a case of scanning a sheet printed with the identifier in the image processing apparatus, the image processing apparatus executes scanning processing according to the scan setting information contained in the identifier.
An image processing apparatus 100 comprises a reading section R and an image forming section P.
The reading section R has a function of scanning and reading images on a sheet document and a book document. The reading section R is provided with a scanning optical system 10 which includes a plurality of reflecting mirrors and image capturing elements, and an auto document feeder (ADF) 9 which is capable of conveying a document to a given placing position automatically. The image on the document placed on a document tray Rt and automatically conveyed by the auto document feeder 9 and the image on the document placed on a document table (not shown) are read by the scanning optical system 10.
The image forming section P has a function of forming a developer image on a sheet based on the image read by the reading section R from the document or the image data sent to the image processing apparatus 100 from an external machine. The image processing apparatus 100 comprises a CPU 801, a memory 802 and a HDD 803. The CPU 801 is an arithmetic processing device such as a CPU (Central Processing Unit), a MPU (Micro Processing Unit) and the like. The CPU 801 carries out various processing in the image processing apparatus 100, and loads and executes the program pre-stored in the memory 802 to achieve various functions.
The memory 802 is a storage section consisting of a RAM (Random Access Memory) serving as a primary storage device and a non-volatile storage device such as a flash memory and the like. The HDD 803 is a storage section consisting of a non-volatile storage device serving as a so-called hard disk drive.
Further, the image processing apparatus 100 is provided with an operation input section 810. The operation input section 810 includes a touch panel type input section for receiving an instruction from a user and a flat-type display section for displaying processing content or a message and the like to the user and displaying a preview image of a printing target before the printing processing.
A copy processing is schematically described below as an example of the processing carried out in the image processing apparatus 100 according to the present embodiment.
First, the sheet picked up by a pickup roller 51 is fed to a sheet conveyance path. The sheet fed to the sheet conveyance path is conveyed by a plurality of roller pairs towards a given conveyance direction.
Then, the images on a plurality of sheet documents automatically conveyed by the auto document feeder 9 continuously are read by the scanning optical system 10.
Next, a control board 800 carries out a given image processing on the image data read by the reading section R from the document. Sequentially, electrostatic latent images of the data subjected to the image processing are formed on photoconductive surfaces of photoconductive drums 2Y, 2M, 2C and 2K for transferring yellow (Y), magenta (M), cyan (C) and black (K) developer images to the sheet.
Then, the developing agent mixed by mixers 4Y-4K in developing devices is supplied by developing rollers (so-called mag rollers) 3Y-3K for the photoconductive drums 2Y-2K on which the electrostatic latent images are formed in the way described above. In this way, the electrostatic latent images formed on the photoconductive surfaces of the photoconductive drums are developed.
The developer images formed on the photoconductive drums in such a way are transferred (so-called primary transfer) to the surface of an intermediate transfer belt 6, and the developer images conveyed through the rotation of the intermediate transfer belt are transferred to the sheet at a given secondary transfer position T.
The developer images transferred to the sheet are fixed on the sheet by a fixing device 7. The sheets on which the developer images are fixed are conveyed on the conveyance path by a plurality of conveyance roller pairs and then discharged to a discharge tray 8 in sequence.
In the image processing apparatus 100, the image forming section P, the operation input section 810, the image reading section R, the control section 800, the fixing section 7 and the HDD 803 are connected with each other through a communication bus 70.
The control section 800, which consists of the CPU 801 and the storage section 802, controls the operations of the image processing apparatus 100.
The CPU 801, which is an arithmetic processing device, loads the computer program pre-stored in the HDD 803 and the like into the memory 802 and executes the computer program to achieve various functions. The storage section 802, which consists of a ROM (read only memory), a RAM (Random Access Memory), an EEPROM (Electrically Erasable Programmable Read-Only Memory) and the like, stores computer program used in the control process carried out by the control section 800 and the data generated during the execution process of the computer program.
