Filed: 1993-01-29
Abstract: PURPOSE:To obtain picture quality which sufficiently fulfills a function as a video telephone even at the same transmission bit rate as the conventional one by preferentially assigning transmission information quantity to the face area of a person, specially, an eye part. CONSTITUTION:In addition to the standard information source coder of H.261, a picture signal transmitting device is provided with a quantization equipment control part 4 which extracts the face area through the use of a macroblock from which a movement vector is detected, detects the eye part from within the face area through the use of a DCT output and lets a quantization step size for the eye area be small at the time of quantization by a quantization equipment 5. Then, transmission information quantity is preferentially assigned to the face part, specifically, eyes and a mouth, being more important information for the other reception party so as to make picture quality superior. Transmission information quantity is preferentially assigned to the face area, specifically, the eye part, of the person and transmission to let the picture quality of the face area, specifically, the eye area, be high quality can be enabled. Therefore, even in low bit rate transmission, the subjectively preferable picture for which an expression is easy to be understood is obtained.

Abstract: PURPOSE:To make it possible to suppress reproduction/magnification and time- sharing of low-sound area by converting a signal, which is generated between an electrode layer and a lamination layer diaphragm that is formed by lamination laying or patterning the electrode layer and a conductor, to a voltage proportional to acceleration and controlling it. CONSTITUTION:The titled device consists of plural magnets 3 which are arranged, sandwiching the lamination layer diaphragm 1 so that magnet poles can be changed reciprocally, a frame 5 which supports the magnets 3, constituting a part of a magnetic circuit, and possesses an acoustic wave aperture,and spacers 6 which fix the periphery in the state where a stretching force is giving to the lamination layer diaphragm 1 and support it in the magnetic field generated by the magnet 3. At this time, as a voice coil has been applied patterning, a speaker driving signal flows in the voice coil 2 and the lamination layer diaphragm vibrates by Fleming's rule to generate a sound wave. Then, by the vibration of the lamination layer diaphragm, the signals are generated according to the vibration of respective lamination layer diaphragm among the divided electrode layers. Thus it can control feedback to suppress the divided vibration of the lamination layer diaphragm 1.

Title: Voice input type dictionary retrieving device
Inventor: NAKAJIMA AKIKO
IPC: G06F17/28
Filed: 1984-02-23
Abstract: PURPOSE:To obtain an appropriate KANJI (Chinese character) conversion output through reference to a conversion deciding table even when a character string including KANA (Japanese syllabary) hard to discriminate a double consonant or normal one is inputted by providing a conversion deciding table. CONSTITUTION:A conversion deciding table 4 stores characters followed by a double consonant in terms of self-dependent character instead of exoticisms. KANA strings served for sentence generation are character-encoded through an external input device and inputted after they are segmented at every word as pretreatment. The KANA string is provisionally given to a consultation control part 3 through a temporary memory device 1 and a code conversion part 2. When the inputted KANA string includes a normal consonant ''tsu'', the code conversion part 2 investigates characters followed by the normal consonant by utilizing the table 4, and generates an auxiliary KANA string in which a normal consonant ''tsu'' is replaced with a double consonant ''tsu'' only when it can be ''tsu'' of a double consonant. Thus when a character string including KANA ''tsu'' hard to discriminate a double consonant or normal one is inputted, an appropriate KANJI conversion output can be obtained.
