Abstract: According to the present invention, an audio recording and playback device operates in such a manner that when a playback instruction member to instruct playback of data is operated during the selection of an audio storage area by a system control unit, audio data selected by an operation unit is played back and an image related to the audio data selected by the operation unit is played back. When the playback instruction member is operated during the selection of an image storage area by the system control unit, only image data selected by the operation unit is played back.

Abstract: In a data recording and reproducing apparatus according to the present invention, audio/image signals are encoded by an encoding portion. A specific switch in a switch operation portion is operated only at the time of recording, and quantized image signals are selectively inputted to the encoding portion by a selection portion. Audio data and image data associated with the audio data are stored in a storage portion, and the audio data and the image data read from the storage portion are decoded by a decoding portion at the time of reproduction. The decoded audio signals are reproduced by an audio reproduction portion, and the decoded image signals are reproduced by an image reproduction portion. Only the image signals associated with the audio signals are selectively inputted to the image reproduction portion by the selection portion.

A second timer unit generates a second time-measurement output by performing a second timer operation different from the first timer operation by the first timer unit. A printing unit prints at least one of the first and second time-measurement outputs generated by the first and second timer units on a film upon film exposure.

Abstract: An instruction for returning to a ROM is written to a position where data is not broken even if a next correction is executed in order not to the content of a register even if an interruption processing for correction and a processing for returning a ROM program are executed. A microcomputer connected through a serial i/O bus, an EEROM, and a correction data writing device comprises a CPU, a RAM, a ROM, a PC comparison register section, a ROM correction processing circuit having a PC value latch section, and a serial i/O section. The CPU sequentially executes an internal sequence control of the microcomputer and a logical operation in accordance with instructions written in the ROM as a program in advance. The RAM temporarily saves intermediate processing data of, e.g. calculation, or saves an adjustment value transferred from the EEPROM when the program is actually executed.

Abstract: A digital fuzzy inference apparatus performs fuzzy inference by time-divisional control. A latch circuit latches an input signal. A parameter storage circuit stores a plurality of sets of parameters for defining membership functions constituting a plurality of fuzzy rules. A parameter switching circuit sequentially and selectively outputs one of the plurality of sets of parameters from the parameter storage circuit in accordance with a clock pulse. Every time one set of parameters are output from the parameter switching circuit, a single operation circuit performs a fuzzy rule operation with respect to the input signal stored in the latch circuit by using a membership function defined by the parameters, and outputs a degree to which the input signal meets the rule. An operation result storage circuit stores the output from the operation circuit at a storage position designated by the output parameters.
