Latest Patents

One of Tomikawa's latest patents is for a digital camera with nonvolatile memory for storing image management data. This invention provides a digital camera that includes a disk drive device, control circuit, flash memory, and flag processing circuit. The design allows power to be supplied to the flag processing circuit and memory at all times. The control circuit reads image management data from a disk and writes it to the flash memory, subsequently issuing a flag rewrite command to the flag processing circuit. This innovation reduces power consumption by ensuring that data is read and written only when the camera's main power is on.

Another significant patent is a method and apparatus for providing and reproducing MPEG data. This apparatus allows any MPEG decoder, without special functionality, to decode and display slow-motion pictures. In normal play mode, the apparatus provides picture data from the original MPEG data. However, in slow-motion mode, it supplies both the original picture data and dummy data to repeatedly display the picture data according to the desired slow-motion speed.
