摘要： A camera capable of imprinting data in which data imprinting means is provided in a control circuit for controlling photographing and power consumption is reduced by appropriately changing intervals for driving a central processing unit (CPU) in accordance to data to be imprinted.A drive signal outputting means 7 is included in the control circuit 1 for controlling photographing and a first drive signal is output from a short time counting means 5 at intervals of one minute and a second drive signal is output from a long time counting means 6 at intervals of 10 minutes, respectively, to a drive signal detecting means 8. When data imprinting mode is set up in a time mode (indicating in unit of minute), the CPU 9 is driven by the first drive signal and time data in a memory 9d is added up at intervals of one minute. When a date mode (indicating in unit of day) is set up, the CPU 9 is driven by the second drive signal and the time data is added up at intervals of 10 minutes. When photographing, the date or time data in the memory 9d is output to data imprinting means 18 to imprint on a film.

摘要： A programmable shutter of the type wherein a shutter blade is opened and closed by means of a stepping motor. The motor is rotated in a forward direction by drive pulses of a predetermined fixed period to gradually open a sector while at the same time a light measuring circuit is started. Thus, at the time when an appropriate exposure quantity is reached, the direction of rotation of the motor is forcibly reversed to effect closing of the sector to attain simultaneous measurement of light and exposure.

摘要： A low cost, low power photometric circuit suitable for use in a low end camera includes a first counter for counting successive pulses produced by a first oscillator having a substantially constant oscillation frequency and a second counter for counting successive pulses produced by a second oscillator having an oscillation frequency which varies in accordance with ambient brightness. The ambient brightness is judged according to outputs of the counters so that even if the oscillation frequency of the second oscillator varies only slightly due to a change in ambient brightness, the slight variation is easily detectable as an accumulated count value. Accordingly, costly, high-precision components are not needed. The low cost photometric circuit requires no microcomputer, analog/digital converter or comparator and can be fabricated in a single integrated circuit operated at a low voltage of 1V or less, and is thus suitable for incorporation into a low end camera.

摘要翻译： 适用于低端摄像机的低成本，低功率测光电路包括：第一计数器，用于计数由具有基本上恒定的振荡频率的第一振荡器产生的连续脉冲;以及第二计数器，用于计数第二振荡器产生的连续脉冲， 振荡频率根据环境亮度而变化。 根据计数器的输出来判断环境亮度，使得即使第二振荡器的振荡频率由于环境亮度的变化而仅稍微变化，所以轻微的变化容易被检测为累计计数值。 因此，不需要昂贵的高精度部件。 低成本测光电路不需要微型计算机，模/数转换器或比较器，并且可以在以1V或更低的低电压操作的单个集成电路中制造，因此适合于并入低端摄像机。

摘要： A program shutter for automatic exposure control including a forwardly/reversibly rotatable step motor for opening and closing a shutter to effect automatic exposure in the control circuit for controlling the operation of the step motor. The control circuit includes stored predetermined shutter mechanism characteristic values. The reversible stepping motor varies the lens aperture in response to a pulsed lens control signal generated by the control circuit. The corresponding value associated with each pulse is varied to be synchronized with and dependent on the shutter mechanism characteristic values and correspondingly varies the rotational power of the reversible stepping motor to overcome detrimental inherent shutter mechanism characteristics and to increase the response efficiency of the shutter.
