    摘要: A variable thresholding circuit for converting an analog signal to a binary signal comprises a comparator to which signals to be converted are applied and a threshold circuit coupled with the comparator in order to provide the threshold level of the comparator, so that the signals applied to the comparator are converted into binary signals in accordance with the threshold level. The threshold level corresponding to the output of the threshold circuit is compensated in accordance with the variations of the levels of the signals applied to the comparator. The threshold level of the comparator is changed to a compensated level when the result calculated from the threshold level and the signals applied to the comparator is smaller than a predetermined value, whereas the threshold level of the comparator is not changed to the compensated one when the result calculated from the threshold level and the signals applied to the comparator is larger than that and the compensation is repeated until the calculated result becomes smaller than the predetermined value.

    摘要: An analog-digital converter comprises a comparator to which signals to be converted are applied, and a threshold circuit coupled with the comparator in order to control the threshold level of the comparator, so that the signals applied to the comparator are converted into binary signals based upon a predetermined threshold level. The threshold level corresponding to the output of the threshold circuit is compensated in accordance with the variations in the levels of the signals applied to the comparator. The threshold level of the comparator is changed to a compensated level when the result, calculated from the average level of the signals approximately corresponding to a predetermined area in a field of the object and that of the signals approximately corresponding to plural areas which are in the vicinity of the predetermined area, is different from that of the preceding frame.

    摘要: In the handheld terminal device, when a message reception unit receives from a host computer a new arrival message indicating a new arrival of a file (or electronic mail), a control unit analyzes the new arrival message to obtain identifier information for identifying the file (or electronic mail) and a telephone number of the host computer. After a line connection to the host computer is established by a handheld phone transceiver unit, a fetch request command for fetching the file (or electronic mail) is transmitted to automatically fetch the file (or electronic mail) from the host computer and make the user know the contents of the file (or electronic mail) by using a display unit. A FAX transmitting user designates a destination handheld terminal device and transmits FAX image data to a communication server (CS). CS stores the received FAX image data and transmits a FAX arrival message to a pager connected to the destination handheld terminal device. A user of the handheld terminal device informed of a FAX arrival by the pager confirms the FAX brief image data contained in the message, and if necessary, calls CS by a handheld phone connected to the handheld terminal device to make CS transmit the FAX image data and refer to the detailed contents thereof.
