摘要： A camera according to the present invention prevents distance measurement errors in remote control shots under high luminance and those in which the distance of a background between right and left objects is measured, by projecting a remote control signal including a ranging signal in a form of infrared beam from a transmitter. The ranging signal, within the remote control signal, includes multiple pulses with different pulse widths, and each pulse width is set so that the number of pulses received by the receiving circuit becomes fewer accordingly as the distance between the transmitter and a receiver provided in the camera becomes larger. When the receiver receives a ranging signal from the transmitter, a distance recognizing unit counts a pulse number of the ranging signal received by the receiver, and recognizes the distance to the transmitter, namely the object, from the relationship of received pulse numbers and distance stored in a memory unit.

摘要： A pre-winding control device of a camera which continues pre-winding from where it left off after a power failure interruption and battery replacement. When a patrone is loaded in the camera, the total number exposures is read from the patrone and the read number of written to an electrically rewritable non-volatile memory E.sup.2 PROM. Subsequently, pre-winding for winding the film from the patrone to a spool is started. For every frame of film wound to the spool, the number of unexposed frames in the patrone is counted down and written to the E.sup.2 PROM. When pre-winding is interrupted due to battery replacement, pre-winding is continued based on the number of unexposed frames stored in non-volatile E.sup.2 PROM.

摘要： A data imprinting device of a camera, when a free mode is set, is responsive to operation by each camera user, and prepares character strings as desired by the camera user and stores the prepared character strings to an electrically rewritable non-volatile memory E.sup.2 PROM. When the free mode is set, character strings stored in the E.sup.2 PROM are read out from the E.sup.2 PROM according to operation by the camera user, and displayed on an imprint display unit and used for imprinting. As character strings prepared by the camera user are stored in the E.sup.2 PROM, the character strings are preserved without being destroyed even when a power source is shut down because a battery is unloaded or used up.

摘要： A data writing/reading device of a camera, in case it has become impossible to write data correctly to certain memory area of an E.sup.2 PROM because of frequent rewritings, can write data to other memory areas of the E.sup.2 PROM, and read out the data. Write requiring data to the E.sup.2 PROM is written to a first predetermined address of the E.sup.2 PROM, and read out immediately after writing. If the write requiring data and the read data are non-coincident, an address which is different from the preceding address is designated, and writing and reading are repeated until the write requiring data and read data become coincident. When the write requiring data and the read data agree with each other, writing to the E.sup.2 PROM is finished. And, an address on which data which agrees with the write requiring data is written, as data, to a second predetermined address of the E.sup.2 PROM which does not overlap with addresses used for writing write requiring data. In reading, the address on which the data which agrees with the write requiring data is written is read out from the second predetermined address, and the data is read out from the E.sup.2 PROM based on the read address.

摘要： A camara control device continues a pre-winding or a first frame setting when a pre-winding or a first frame setting is stopped in the middle because a battery of the camera is taken out or because of exhaustion of the battery and after that another battery is loaded. The camera control device writes a pre-wind signal to an electrically rewritable non-volatile memory E.sup.2 PROM when a pre-winding is started and erases the pre-wind signal in the E.sup.2 PROM when the pre-winding is finished, and writes a first frame set signal to the E.sup.2 PROM when a first frame setting is started and erases the first frame set signal in the E.sup.2 PROM when the first frame setting is finished. If the pre-winding or the first frame setting is stopped in the middle, the pre-wind signal or the first frame set signal in the E.sup.2 PROM is not erased. The camera control device, responsive to loading of the battery to the camera, continues the pre-winding or the first frame setting when the pre-wind signal or the first frame set signal is left in the E.sup.2 PROM.

摘要： A self-photographing method for an autofocus camera, wherein, upon depression of a shutter release button, the subject distance data are detected a plurality of times at periodic intervals, and a predetermined exposure operation, that is, an actual shutter release operation is automatically executed using the autofocus system when the detected subject distance data have changed from each other. The distance data are repeatedly detected and compared with each other until these distance data differ from each other. If the distance data have been equal for a predetermined time interval from the shutter release button depression, then the actual shutter release operation is executed, or is called off and the self-photographing is terminated. It is preferred that the detected change of distance be a decrease of distance, indicating that the photographer has stepped into the picture, whereupon the measured distance becomes his distance in place of the background distance.

摘要： A camera has a two lens group zoom system composed of a front lens group and a rear lens group, and a home position check apparatus of the rear lens group driven by a stepping motor. The home position check apparatus is so arranged that a detection as to if the rear lens group is located at the home position is started only when the rear lens group reaches the predetermined position before the home position. Before the rear lens group reaches the predetermined position, only the movement of rear lens group to the home position is carried out but the home position check of rear lens group is not.

摘要： A camera includes a lens barrel which can be retracted into a camera body, and a lens barrel storage control apparatus. The lens barrel has a front lens group mounted in a front end portion thereof and a rear lens group movably disposed therein. The lens barrel storage control apparatus controls a DC motor for retracting the lens barrel, if the rear lens group is in a safe area where it will come into no contact with a film in retracting the lens barrel into the camera body, and then controls a stepping motor for locating the rear lens group to a final standby position after completion of storage. On the other hand, if the rear lens group is out of the safe area, the control apparatus controls the stepping motor for locating the rear lens group to the rearmost position in the safe area, and controls the DC motor for retracting the lens barrel.

摘要： A camera includes a lens barrel which can be retracted into a camera body, and a lens barrel storage control apparatus. The lens barrel has a front lens group mounted in a front end portion thereof and a rear lens group movably disposed therein. The lens barrel storage control apparatus, first, controls a stepping motor for driving the rear lens group to locate the rear lens group at a standby position in the barrel, and then controls a DC motor for driving the lens barrel to retract the lens barrel into the camera body while keeping the rear lens group at the standby position. Also, when it is detected that the rear lens group is not located at the standby position, the control apparatus controls the DC motor to locate the lens barrel at a suitable position within a range where the lens barrel can be set in a photographable state.
