Abstract: An image capturing apparatus illuminates an object and captures an image of the object using the reflected light from the object. On a circuit substrate mounted an image sensor, a plurality of light-emitting devices are mounted in the peripheral positions of the image sensor. By means of a ring-shaped light guide member, the light from the plurality of light-emitting devices is guided to an image capturing range, so as to illuminate the object. With this, by mounting a light receiving system and a light emitting system on an identical substrate, miniaturization can be achieved, and the image capturing range can be illuminated by substantially uniform light. Also, using the ring-shaped light guide member, an optical unit is housed inside the ring, thus enabling further miniaturization.

Abstract: An image capturing apparatus illuminates an object and captures an image of the object using the reflected light from the object. The image capturing apparatus includes an image sensor for capturing an image of the object by receiving reflected light, distance-measuring light-emitting devices for irradiating the object with spot light, and a control circuit for driving the distance-measuring light-emitting devices, detecting the spot light positions of the distance-measuring light-emitting devices from an image captured by the image sensor, and obtaining the distance to the object. The image sensor provided for capturing an image of the object can be used as a photodetector device for distance measurement. With this, it becomes unnecessary to separately provide a photodetector device for distance measurement, which enables miniaturization of the image capturing apparatus, as well as cost reduction.

And time-triggered scheduling and event-triggered scheduling are separately performed. Conversion of FlexRay and CAN messages can be efficiently implemented.

Abstract: A communication terminal capable of preventing a circuit from being released when a hook key is operated in the case the circuit is being closed forcibly. The communication terminal is capable of informing the functions capable of being used in the case the circuit is being closed due to the malfunction of the recording unit. If a recording unit fails to operate and the image memory is exhausted, and when it is set to close the telephone line based on the operation of the circuit closing key, the facsimile receiving is prevented from being carried out by closing the telephone line. The operation of the hook key is invalidated under this condition. Therefore, the telephone line is not released even if the hook key is operated. Thus, when the telephone line is being closed forcibly, the telephone line L is not released even if the hook key is operated.

Abstract: An image shot by a shooting unit is stored in a shot image storing unit. An expected shooting state storing unit stores expected shooting state information which represents an expected shooting state of an object to be shot. A guide direction determining unit references the image stored in the shot image storing unit and the expected shooting state information, and determines in which direction the object to be shot, which is shot by the shooting unit, is to be guided. A guide direction instruction outputting unit notifies a user of a result of the determination made by the guide direction determining unit.

Abstract: When an image transmitter and a mobile phone are connected, it is determined whether or not a connection (communication) is established between a communication section and the mobile phone. If it is determined that the connection is established, the image transmitter transmits to the mobile phone a signal to request the mobile phone to obtain identification information given to the mobile phone. The image transmitter determines whether or not pre-stored identification information in the storage unit and the obtained identification information match. If it is determined that the identification information matches, the image transmitter reads image data stored in the storage unit and transmits the image data to the mobile phone.

Abstract: It is determined whether or not a connection is established between the communication section of an image transmitter and a mobile phone. If it is determined that the connection is established, a request command is transmitted to the mobile phone to obtain the model information of the mobile phone. When the mobile phone receives the request command, it reads the model information from an internal memory, and transmits the model information to the image transmitter. When the image transmitter obtains the model information in response to the request for the model information, it reads conversion information corresponding to the obtained model information with reference to a conversion table. Then, the image transmitter converts the image data stored in a storage unit, based on the read conversion information, and transmits the converted image data to the mobile phone of the image transmitter through the communication section.
