  • Patent number: 7907825
    Abstract: In an image-recording device using a disk-type recording medium generated under the DVD+RW standard, a disk information-acquisition unit 250 acquires information about a disk 49, a disk-determination unit 260 determines that the disk 49 is a subject disk that is of a DVD+RW type and that stores video data generated by using a DVD menu and/or still-image data recorded onto the disk, an additional recording-control unit 220 controls additional recording performed for the disk 49 according to a result of the determination performed by the disk-determination unit 260, and a message display-control unit 270 makes a display unit 280 show a confirmation message used for shifting to a mode relating to the pros and cons of performing the additional recording and/or a message adapted to confirm that the DVD menu and the video data are updated, so that a mismatch which may occur between the DVD menu and/or the video data, and recorded image data is reduced.

  • Patent number: 7903013
    Abstract: Operating speed as well as output accuracy of a D-A converter is enhanced. With a semiconductor device including unit current sources, and unit current source switches, plural current source elements constituting each of the unit current sources are disposed so as to be evenly dispersed, thereby reducing errors of the current source element, dependent on distance while the unit current source switches are concentratedly disposed in a small region, thereby mitigating delay in operation, attributable to parasitic capacitance. In addition, with the semiconductor device including R2R resistance ladders, the R2R resistance ladder is provided on the positive and the negative of each of the unit current source switches, and the respective R2R resistance ladders are shorted with each other at respective nodes on a unit current source switch-by-unit current source switch basis, are rendered identical in length, thereby cancelling out a nonlinearity error attributable to wiring parasitic resistance.
