An image processing system includes a portable terminal and an image processing apparatus. The portable terminal includes a transmission processing unit that transmits each of the image data in units of the page of the document. The image processing apparatus includes a reception processing unit, a determination processing unit, and an output processing unit. The reception processing unit receives each of the image data in units of the page of the document transmitted from the portable terminal. The determination processing unit determines a page sequence of each of the image data in units of the page of the document based on each of the image data in units of the page of the document received by the reception processing unit. The output processing unit outputs each of the image data in units of the page of the document received by the reception processing unit in accordance with the page sequence.

An image processing apparatus having a reading unit that can read both sides of an original in parallel has a processing unit that processes image data obtained by the reading unit reading an original. The apparatus controls to execute processing by the processing unit on image data of a first surface of the original and reading of a second surface of the original in parallel. The apparatus determines whether or not to start processing by the processing unit on image data of the second surface of the original when processing by the processing unit on the image data of the first surface of the original completes, and in accordance with the determination result, the apparatus controls of a start of processing by the processing unit on the image data of the second surface of the original.

A control apparatus includes a storing unit, a determining unit, a first notification unit, a selection unit, and a second notification unit. The storing unit stores attribute information of sheets to be stored in sheet holding units. The determining unit determines whether attribute information of sheets to be used by a job corresponds to the stored sheet attribute information. The first notification unit notifies, in a case where the determining unit determines that the attribute information does not correspond, a user that the attribute information does not correspond to the sheet attribute information. The selection unit selects the stored sheet attribute information to change the attribute information of sheets to be used by the job. The second notification unit notifies, in accordance with selection of the sheet attribute information, the user that the attribute information of sheets to be used by the job corresponds to the stored sheet attribute information.

An image reading apparatus includes a transparent document platen on which a document is to be placed, a reader configured to read an image of the document placed on the document platen, a controller configured to perform a reading mode to cause the reader to read a document tucked in a storage member, which has a transparent portion and can store the document, in a state in which the storage member in which the document is tucked is placed on the document platen so that the transparent portion contacts the document platen, and a display configured to display, in the reading mode, a screen indicating an orientation in which the storage member is to be placed on the document platen.

In an image reading device including a document platen, a document holder, multiple light sources, and a close contact type image sensor, the light sources are sequentially turned on and the image sensor individually reads light of multiple different colors reflected from a document in a main scanning direction. When the document holder is opened, in an area determination process, a first scanning area where a difference between output values of the image sensor when the light sources are sequentially turned on is within a predetermined threshold value range, and a second scanning area where the difference is outside the predetermined threshold value range are determined in an entire scanning area of the image sensor. A document size in the main scanning direction is detected based on a position of a boundary in the main scanning direction between the first and second scanning areas determined in the area determination process.

A processor randomly selects a page image group corresponding to a predetermined number of pages, such as five pages, from scan images of all the pages of a book, and clips a predetermined area (evaluation area) from each of the selected page images. Subsequently, the processor performs, on each clipped image, color correction and compression at a compression rate in accordance with an image quality specified via a user interface, and derives the data volume of each clipped image subjected to the processing. In addition, based on the data volumes of the clipped images subjected to the processing, the processor derives estimated one page data volumes Then, by using the estimated one page data volumes, the processor derives an estimated data volume of a digital book corresponding to the total pages of the book.

An image reading apparatus is provided with: a reading processing unit which moves a reading unit, causes a light emitting unit to emit a first amount of light, reads an electric charge generated by a photoelectric conversion unit, and reads an image of a document placed on a document placing surface on the basis of the read electric charge; and a detection processing unit which causes a light emitting unit to emit a second amount of light greater than the first amount of light, reads an electric charge generated by the photoelectric conversion unit, and detects the size of the document placed on the document placing surface on the basis of the read electric charge.

A document feed portion of an image reading device is capable of feeding a document placed on a first document placement portion, to a predetermined reading position. A size detection portion detects a size of the document placed on the first document placement portion. A storage processing portion stores size information indicating the size of the document detected by the size detection portion, into a predetermined storage medium. An image reading portion performs a reading process of scanning a read surface of the document placed on a second document placement portion, to read an image. A setting portion sets the size information stored into the storage medium by the storage processing portion, as size information to be used for the reading process by the image reading portion.

An image processing apparatus including: a first housing; and a second housing, the second housing including: a base part; a supporting part; an image reader; and a detector, the first housing including: an image forming unit and a cover, wherein: the cover has a 1st region disposed on a lower position of the detector and a 2nd region disposed on an upper position of a moving range of a recording head; the 1st region has a recessed part recessed downward, an inner bottom surface of the recessed part being disposed at a position lower that an upper edge position of the 2nd region; the base part has a housing part; and a lower edge of the detector is lower than the upper edge position of the 2nd region.

A non-transitory computer readable medium stores a print control program causing a computer to function as a designation information acquisition unit, a paper feed information acquisition unit, and a designation information changing unit. The designation information acquisition unit acquires designation information indicating a paper feed designation of recording paper and a paper designation from print data that is generated by a printer driver based on the paper feed designation and the paper designation. The paper feed information acquisition unit acquires paper feed information indicating paper information of the recording paper and paper feed configuration of the recording paper mounted on a printing device, from the printing device before the print data is transmitted to the printing device. The designation information changing unit compares the designation information and the paper feed information and changes the designation information when a certain condition is met.
