摘要:
In an image communication apparatus for communicating a color image with a distant apparatus according to the ITU-T recommendations upon line connection, an original image is read by a scanner unit, and the size of the read original image is identified. If the identified size of the original image is smaller than the page size defined by the ITU-U recommendation, image data is generated by reading the original image upon adding invalid data to the original image to make it have a main scanning length equal to the main scanning length of the minimum page size defined by the ITU-T recommendation in reading the original image through the scanner unit, and the image data is compressed by a JPEG compressing unit and transmitted. In this case, the valid image area of the compressed data is set in accordance with the size of the original image. This allows the receiving side to read only the valid image area, decode the valid image area, and reproduce the image.

A multi-function apparatus having a wider variety of uses and easily employed when carrying a USB cable only without having a power source cord. The apparatus includes means for detecting a connection between the USB interface and the PC, means for detecting a connection to the power line, and control means for selecting a function depending on a detected state of the connection between the USB interface and PC and a detected state of the connection to the AC power line. All the functions in the multi-function apparatus are operable in a connected state of the AC power line to the AC power source, while even in an unconnected state of the AC power line to the AC power source, if the USB interface is connected to the PC, a possible operation is enabled using electric power of 5 V at 500 mA supplied from the PC.

An image forming apparatus which is capable of efficiently registering apparatuses in a slave apparatus list. The image forming apparatus has a partner apparatus list as the slave apparatus list which stores information on the image forming apparatuses as candidate slave apparatuses so as to select a slave apparatus for use in executing cascade copy. When the image forming apparatus is selected as a master apparatus, a CPU thereof selects a slave apparatus from the image forming apparatuses registered in the partner apparatus list. When the image forming apparatus is selected as a slave apparatus, the CPU determine whether or not the information indicative of the copy mode has been received from a master apparatus. If the information indicative of cascade copy has been received, information on the master apparatus is stored in the partner apparatus list.

An apparatus supplies power to a communication unit that communicates with an external apparatus, and manages history information for each communication sequence in the communication unit in a mode where power supplied to a control unit is stopped. At that time, the apparatus assigns identification information unique to the communication unit to the history information when the apparatus is in a mode where power supplied to the control unit is stopped, and makes control when power supplied to the control unit is stopped or when the apparatus returns to the mode in which power is supplied to the control unit so that continuity of the history information managed by the control unit is ensured.

This invention provides an information processing apparatus which shortens the memory access time and reduces the cost while ensuring data reliability. To accomplish this, the information processing apparatus shifts each write start timing so that data to be written in at least one memory is not influenced by noise during write when writing the same information in a plurality of memories. When reading data from a plurality of memories, the information processing apparatus compares the data with each other to estimate normal data.
