  • Patent number: 9100594
    Abstract: According to an embodiment, an image processing apparatus has a monitoring unit, and an arbitration unit. The monitoring unit monitors a data amount in a first transfer buffer of a first image processing unit, and a data amount in a second transfer buffer of a second image processing unit. The arbitration unit arbitrates, so that when the data amount in the first transfer buffer becomes not less than a predetermined first threshold value, the number of times of data transfer from the first transfer buffer to a main memory is increased. Furthermore the arbitration unit arbitrates, so that when the data amount in the second transfer buffer becomes not more than a predetermined second threshold value, the number of times of data transfer from the main memory to the second transfer buffer is increased.

  • Publication number: 20060020823
    Abstract: After power-on of an MFP, a data protecting apparatus receives an encryption key from a host server via a network I/F, stores the received encryption key in an encryption key storage unit, delivers the encryption key to a decryption key generation unit, and stores a generated decryption key in a decryption key storage unit. Subsequently, an HDD controller reads out master data that is written in an HDD. A data decryption unit decrypts the master data, using the decryption key stored in the decryption key storage unit. A REF data generation unit generates reference data. A data comparator compares the decrypted master data with the generated reference data. If the decrypted master data coincides with the reference data, the data protecting apparatus determines that the encryption key is normal. If they do not coincide, the data protecting apparatus determines that the encryption key is abnormal.

  • Publication number: 20030046565
    Abstract: A first key is generated at a server from contents information of contents data to be distributed. A second key is generated at the server from a variable parameter, a H/W key ID, and the first key, and then the generated second key is sent to a user terminal. From the variable parameter, the H/W key ID, and the second key, the first key is decrypted at the user terminal. The contents data to be distributed is encrypted by using the first key at the server. The encrypted contents data is sent to the user terminal. The encrypted contents data is decrypted at the user terminal by using the decrypted first key.

  • Patent number: 5592210
    Abstract: A method and an apparatus for driving an edge emission type line head having a plurality of edge emission type EL elements grouped in blocks. Each group of the edge emission type EL elements has a channel electrode connected to a channel driver and has a common electrode connected via a matrix circuit to common terminals of a common driver. The channel driver outputs voltages while the common driver outputs alternately a positive and a negative high voltage. If something happens to stop the function of the line head in operation, the output of the common driver is stopped after a pair of a positive and a negative high voltage is output by one common terminal, or after one-line output is effected by the common driver. This helps prolong the service life of the edge emission type EL elements constituting the line head.

  • Patent number: 5568178
    Abstract: An apparatus for driving edge-emission type electroluminescent elements to emit light to expose an image carrier and to form image data clearly on the image carrier. The edge-emission type electroluminescent elements have electrodes and emit light when a potential difference across the electrodes exceeds a preset threshold value. Electric pulses are supplied to the electrodes of the edge-emission type electroluminescent elements to cause the potential difference across the electrodes to exceed the preset threshold value so that the edge-emission type electroluminescent elements emit light. A series of pulses are supplied for each pixel of image data.
