  • Publication number: 20060039674
    Abstract: An image editing apparatus creates photo movies from frame images read out from a memory card. A file for the frame images stores frame classification information in relationship to the image data. An editing condition setup section reads out a scenario form from a HDD. The scenario form determines plural scene categories. The editing condition setup section assigns the frame images to the scene categories based on the frame classification information to complete a scenario. A photo movie creating section follows the scenario to create a photo movie. The scenario determines a special effect, BGM, and the like for each scene category, and all the frame images belonging to the same scene category are edited and processed as a group.

  • Patent number: 6954410
    Abstract: A laser waveform generation function is provided in a laser driving waveform generator 2 near a laser 3. A recording clock generator 9 is included in the laser driving waveform generator 2 to generate a clock with a frequency higher than that of a synchronizing clock 202. This allows a recording laser current (waveform) to be generated without transmission of a high frequency signal from the modulator 6. Further, because the synchronizing clock 202 is stopped upon a reproduction operation including reproduction operation in an ID unit, undesired effects on a reproduction operation such as ID reproduction can be reduced. Because the response speed of the recording clock generator 9 can be changed, a high precision clock can be generated. Thus, a high-precision recording laser current (waveform) can be generated.

A thickness of the stay is set to be smaller than a width, and a cross sectional shape thereof is formed so as to be in a substantially thin convex shape. A width in a base end wall portion of the outer rack is formed so as to be larger than a width of a side surface wall portion corresponding to a thickness of the outer rack, and the outer rack is formed in a substantially thin C cross sectional shape. It is possible to make a thickness of a slide mechanism about a gear with of rack gears lined up in an axial direction in the side surface wall portion by making the width of the side surface wall portion slightly larger than the gear width of the rack gear.
