  • Patent number: 7694213
    Abstract: A video content creating apparatus includes a computer. The computer registers photographic image data input from a photographic input device and meta-information set in relation to the data in a database. After retrieving photographs based on the meta-information, the apparatus selects the photographs to be used for a reminiscence video and decides the reproduction order of the photographs. After registering a BGM playlist, the apparatus reproduces the photographs and BGM for creating the reminiscence video. If there are any regions, the apparatus displays the regions on a monitor while aligning them in sequence according to the meta-information on them. Upon completion of generation (rendering) of a series of reminiscence video contents, the apparatus creates the reminiscence video by saving the rendering results in Flash movie format, for example.

  • Patent number: 7551600
    Abstract: A call system for performing a voice call by an Internet call function using a known telephone terminal. In a multifunction machine serving as the telephone terminal, the output destination and the input source of audio signals input/output from/to a transmitter/receiver may be switched to an audio I/F. In the switched state, audio based on audio signals input/output from/to an outside source through the audio I/F is output/input from the transmitter/receiver. Therefore, when the multifunction machine is connected to a PC having the Internet call function such that audio signals can be input/output through an audio cable, an indirect audio call by the Internet call function with the transmitter/receiver is available. When an incoming call from a telephone line network is received, reception of the incoming call is notified so that a user can confirm the reception of the incoming call during the voice call by the Internet call function.

  • Patent number: 6894671
    Abstract: A display apparatus is capable of adapting sufficiently to an increase in the display frequency even when using an optical modulation element which has a fairly low response speed and can rewrite an image at a high speed. The display apparatus separately performs mapping of display data for an optical modulation element of each pixel and application of gradation information. The display apparatus divides a display period of one frame into a plurality of sub-frames, controls the input value for the optical modulation element independently per each sub-frame in the plurality of sub-frames, and displays an image with a gradation display using the optical modulation element.

  • Patent number: 6694403
    Abstract: During a normal update process, a password transmitted from a personal computer is compared with password already stored in a flash memory. When the passwords match, a transmitted program is written over the stored program. When a change mode is set by a user, the transmitted password is not compared with the stored password. The transmitted program is written over the stored program. Alternatively, even when the two passwords are compared and the two passwords do not match, if the change mode is being set, the transmitted program is written over the stored program. Accordingly, during the change mode, regardless of whether or not the transmitted password matches the stored password, the transmitted program is written over the stored program.
