A solid-state imaging device with a variable (continuous) electronic shutter function comprises an imaging area where unit cells with photodiodes acting as pixels are arranged two-dimensionally, read lines for driving the read transistors in each pixel row, vertical selection lines for driving the vertical selection transistors in each pixel row, a vertical driving circuit for selectively driving vertical selection lines, vertical signal lines for outputting the signal from each unit cell in the pixel rows driven sequentially, and a row selection circuit for controlling the vertical driving circuit in such a manner that the vertical driving circuit drives the read transistors in each pixel row with the desired signal storage timing and signal read timing twice in that order and thereby drives the vertical selection transistors in the pixel row in synchronization with the signal read timing.

Solid-state imaging device

The radio telephone apparatus which is mounted on a car is disclosed. An operational state of the apparatus is memorized therein as a power flag. On the basis of the power flag, the apparatus may be recovered to an operational state at a time when an ignition switch of the car is turned off. More specifically, the power flag may be referred every time a position of the ignition switch is changed from OFF position to ON position. At the event, if the flag indicates that the apparatus was in an operative state at a time when the ignition switch of the car is turned off, the power supply to the apparatus is resumed in response to the position change of the ignition switch. Contrarily, if the flag indicates that the apparatus was not in an operative state, the power supply to the apparatus is not initiated even if the position of the ignition switch is changed.

Mobile radio telephone apparatus

A telecommunication apparatus adapted to be used with a detachable memory device is disclosed. The detachable memory device such as an IC card are capable of storing information relating to a particular user. When the detachable memory device is connected to the apparatus, the apparatus retrieves information relating to the particular user out of the detachable memory device. Thereafter, the apparatus may perform one or more of functions on the basis of the retrieved information. When the detachable memory device is connected to the telecommunication apparatus, the apparatus detects the presence of identification information stored in the detachable memory device. In the event that the identification information is not detected, the apparatus provides an indication to a user so as to request the user to enter an identification information. After that, if an identification information is entered into the apparatus by the user, the entered identification number is sent to the detachable memory device and stored therein under the control of the apparatus. On the other hand, in the event that the identification information is detected, the apparatus provides an indication representative of the detected identification information to the user of the apparatus.

Telephone apparatus using a detachable memory device

A speech recognition system that detects a similarity between each speech pattern which has already been registered in the system and a speech pattern newly generated in response to the user's utterance made while the system is in a registration mode. The system further provides to the user in the registration mode information representing the detected similarity. The speech recognition system may be incorporated into a telephone apparatus or a radio telephone apparatus, in which a call origination may be automatically made in response to the user's utterance.

Speech recognition system for telephony

Telephone apparatus in which a call may be made in response to utterances of a user by speech recognition without manually dialing a telephone number. The telephone apparatus includes a storage device for storing a set of parameters corresponding to an expected speech signal, which are used for recognizing the user's subsequent utterance and/or for indicating differences between the utterance and the stored signal. The telephone apparatus further includes a storage device for storing the speech signal so that the stored speech signal can be reproduced. The reproduced speech signal is used to confirm the stored speech signal. The stored speech signal may be reproduced in response to a user's key operation when the telephone apparatus is in a confirmation mode and in response to a user's utterance when the telephone apparatus is in a registration or voice calling mode.
