  • Patent number: 7412390
    Abstract: The emotion is to be added to the synthesized speech as the prosodic feature of the language is maintained. In a speech synthesis device 200, a language processor 201 generates a string of pronunciation marks from the text, and a prosodic data generating unit 202 creates prosodic data, expressing the time duration, pitch, sound volume or the like parameters of phonemes, based on the string of pronunciation marks. A constraint information generating unit 203 is fed with the prosodic data and with the string of pronunciation marks to generate the constraint information which limits the changes in the parameters to add the so generated constraint information to the prosodic data. A emotion filter 204, fed with the prosodic data, to which has been added the constraint information, changes the parameters of the prosodic data, within the constraint, responsive to the feeling state information, imparted to it.

  • Patent number: 6029016
    Abstract: A camera which uses a film cartridge having a magnetic recording part for each frame portion thereof and writes magnetic information in the magnetic recording part of each frame, in rewinding the film after completion of photographing on all frames, is arranged to effectively prevent information from being recorded again at the time of rewinding the film for any frame having magnetic information already recorded in a case where the film cartridge loaded into the camera contains a film in which part of frames have been already exposed. In the camera, when a film cartridge having some of film frames already exposed is loaded, the camera stores the position of a leading unexposed frame and to permit recording of magnetic information up to the leading unexposed frame in performing the recording action at the time of film rewinding.

  • Patent number: 5408292
    Abstract: An image processing apparatus for visual axis detection in which a frame transfer type CCD is used as an area sensor for converting an incident eyeball image into an electrical signal. Use of the frame transfer type LCD will widen the light receiving area on the surface of the CCD and enhance the numerical aperture, as to well as greatly enhance the probability of detection of Purkinje's image and enhance the sensitivity to the infrared range to thereby make the Purkinje's image detectable by a smaller quantity of illumination.

  • Patent number: 4908552
    Abstract: This invention concerns with an electronic flash unit in which, as two capacitors of large and small capacitances are charged, even when a trigger operation is actuated before the capacitor of large capacitance is fully charged, it is made possible with the help of the charge from the capacitor of small capacitance to fire the flash tube. Particularly in application of the invention to the above-described type of electronic flash unit, as the battery for use in charging the capacitors also serves to drive another load for a time which can fall in coincidence with the period of charging the capacitors, when the driving of the load is started, the charging of the capacitor of large capacitance is inhibited while the charging of the capacitor of small capacitance is permitted to go on, thereby it being made possible to carry out the driving of the load with high reliability so that the correct flash exposure is made while still maintaining the quickness of snap shots.

  • Patent number: 4806963
    Abstract: In a system for setting the aperture in a camera for flash photography, a minimum aperture is computed in response to parameters such as distance to an object, stroboscopic guide number and film sensitivity. In one embodiment, a predetermined aperture value is preestablished in the system and the computed minimum aperture is compared therewith. Where the computed minimum aperture is below such predetermined aperture value, such computed minimum aperture is used in flash photography. On the other hand, when the computed minimum aperture is above such predetermined aperture value, an aperture larger than the predetermined minimum aperture value is used in flash photography. Other embodiments for flash aperture setting are also set forth.
