An image reading apparatus includes an image sensor to read a document, a sensor to detect whether the document is loaded on the image reading apparatus, and a processor to, when the sensor detects the document is loaded on the image reading apparatus, and before a scan instruction is input to the image reading apparatus, control the image sensor to execute a pre-scan job with respect to the loaded document using a default set value.

An image forming apparatus includes a detector, a calculator, and a corrector. The detector receives brightness values obtained from an image printed based on image data. The image includes a plurality of streaks and non-streak portions having image density differences with the plurality of streaks. The detector detects a first streak width, a first brightness difference between a brightness value of the first streak and a brightness value of a non-streak portions, a second streak width wider than the first streak width, and a second brightness difference between a brightness value of the second streak and a brightness value of a non-streak portion. The calculator calculates a correction coefficient corresponding to the first streak width based on the first brightness difference and the second brightness difference. The corrector corrects an image density corresponding to the first streak width in the image data based on the calculated correction coefficient.

Devices, systems and methods are disclosed for reducing a perceived latency associated with uploading and annotating video data. For example, video data may be divided into video sections that are uploaded individually so that the video sections may be annotated as they are received. This reduces a latency associated with the annotation process, as a portion of the video data is annotated before an entirety of the video data is uploaded. In addition, the annotation data may be used to generate a master clip table and extract individual video clips from the video data.

An image forming apparatus includes: a first memory for temporarily storing therein image data output to an image forming unit; a data processing processor for reading the image data; a second memory for temporarily storing therein the image data; and a main processor for causing the data processing processor to sequentially read the image data, wherein the data processing processor includes: data transfer units; a transfer control unit; and a table, the main processor sets a start address and a size and instructs the transfer control unit to activate the data transfer units, the transfer control unit divides a size of image data and sets a start address and a size of divided image data, the data transfer units read corresponding image data and output it to the second memory, and the transfer control unit subsequently controls the data transfer units and notifies the transfer completion to the main processor.

An image processing apparatus includes a volatile first memory, a non-volatile second memory, a hardware processor, a power supply and a delay unit, wherein the hardware processor executes a process defined by a program, after execution of the program ends, deletes data stored in the second memory by execution of the program by overwriting the stored data with predetermined data, in response to the generation of the stop trigger, stores data, stored in the first memory, in the second memory as a snapshot, in response to generation of a start trigger, transfers the snapshot stored in the second memory to the first memory, and in the case where prospective deletion data that is to be deleted is stored in the second memory in a stage where the stop trigger is generated, overwrites the prospective deletion data with the snapshot without overwriting the prospective deletion data with the predetermined data.

A control server may receive, from a multifunction peripheral, instruction information; send a scan instruction for generating first scan data to the multifunction peripheral in a case where the instruction information is received, send, to the multifunction peripheral, a sending instruction for sending the first scan data to a predetermined server in the case where the instruction information is received, send, to the multifunction peripheral, a print instruction for receiving, from the predetermined server, second scan data obtained using the first scan data, and for printing the document image represented by the second scan data in the case where the instruction information is received and executes a predetermined process for saving, in the destination apparatus, third scan data obtained using the first scan data in the case where the instruction information is received.

The calculator calculates a correction coefficient corresponding to the first streak width based on the first brightness difference and the second brightness difference. The corrector corrects an image density corresponding to the first streak width in the image data based on the calculated correction coefficient.

A printer multifunction system includes a printer having a printer controller and a scanner having a scanner controller and a memory configured to store data obtained by reading a print original by a sensor. The printer and the scanner are connected to a network to which a computer is connected, wherein the scanner controller determines whether to transmit the data stored in the memory to the printer or the computer, based on at least one of a state of the printer, a reading setting of the scanner, and a state of the memory, and causes the scanner to transmit the data stored in the memory to a destination determined by the scanner controller. The printer controller receives the data from the scanner in a case where the data is transmitted to the printer, and receives the data from the computer in a case where the data is transmitted to the computer from the scanner, and the printer controller causes the printer to execute a printing operation, based on the data.

Generally, a scanner of the present embodiment, which reads a first surface with a first reading section configured to read the first surface of a sheet and a second surface with a second reading section configured to read the second surface opposite to the first surface of the sheet, executes individual processing on a first reading image of the first surface and a second reading image of the second surface.
