An electronic apparatus includes the following elements. A circuit forming device forms a circuit configured in accordance with configuration information. A first storage unit stores first configuration information externally obtained via a first communication line. The first configuration information is used for forming a first circuit implementing a function including a first communication function in the circuit forming device. A second storage unit stores second configuration information different from the first configuration information. The second configuration information is used for forming a second circuit implementing a function including the first communication function in the circuit forming device. A recovery controller performs control so that the second circuit is formed in the circuit forming device by using the second configuration information, upon the occurrence of an error in communication via the first communication line when the first circuit is formed in the circuit forming device by using the first configuration information.

An arbitration device includes an arbitration section, a counter, and a changing section. While write request signals and read request signals for a transfer path, are inputted from request sources, the arbitration section arbitrates an order that the write and read request signals use the transfer path, and when arbitration is settled, outputs use permission signals to the request sources. The changing section changes a time from outputting of the write request signals until inputting of the write request signals to the arbitration section, and/or a time from outputting of the use permission signals for the write request signals until inputting of the use permission signals to the request sources.

An electronic device includes a reprogrammable logic element, a configuration data storage, a reading section, a dummy data creating section, a skip determination section, a writing section and a control section. The configuration data storage stores configuration data for the reprogrammable logic element. The reading section successively reads the configuration data from the configuration data storage. The dummy data creating section creates dummy data. The skip determination section determines as to whether or not the configuration data is to be skipped. The writing section writes the configuration data or the dummy data into the reprogrammable logic element. If the skip determination section determines that the configuration data is to be skipped, the control section controls the dummy data, which is created by the dummy data creating section, to be sent to the writing section.

There are provided an image processing apparatus and an image processing method which are capable of correctly determining the scaling factor of an input image containing a specific image composed of a predetermined number of partial images. When an input image is inputted, the partial image detection unit detects information about partial images. As information about partial images, information indicating whether partial images exist, the size of the partial images, and the like are outputted. The information about partial images is outputted for each pixel of an input image and a pattern composed of the information about partial images is obtained. The scaling factor estimation unit uses a pattern composed of the information about partial images outputted from the partial image detection unit to detect an area where a predetermined number of partial images exist, and determines the scaling factor of the input image from information of the area.
