    摘要: A stepping motor control circuit includes a rotation detection circuit that detects an induced signal and detects whether or not the induced signal exceeds a predetermined reference threshold voltage in a detection segment having a plurality of detection areas, and a control unit that determines the state of rotation of a stepping motor on the basis of a pattern indicating whether or not the induced signals exceed the reference threshold voltage and, on the basis of the result of detection, controls the driving of the stepping motor with anyone of a plurality of main drive pulses different from each other in energy or a correction drive pulse having larger energy than the main drive pulse. An ineffective area is provided between at least the two detection areas, and the control unit determines the state of rotation of the stepping motor without considering the induced signal.

    摘要: A control unit is provided which drives a stepping motor in a first mode in which a driving pulse is selected between one kind of main driving pulse and a correction driving pulse with energy greater than the one kind of main driving pulse in accordance with a rotation state of the stepping motor and the stepping motor is driven or a second mode in which the driving pulse is selected among plural kinds of main driving pulses and a correction driving pulse with energy greater than the plural kinds of main driving pulses in accordance with the rotation state of the stepping motor and the stepping motor is driven. The control unit switches a mode between the first and second modes depending on whether the voltage of a secondary cell serving as a power supply exceeds a switch voltage and drives the stepping motor.

    摘要: An image synthesis device selects frame images in an order stored in a DRAM, and calculates the characteristic amount of the selected frame image. The image synthesis device searches a block having the calculated characteristic amount in a next frame, and calculates a moving vector. The image synthesis device sets an extraction width which is a width of a partial image to be extracted based on the calculated moving vector, and extracts an image at the extraction width from the central line in a current frame image. The image synthesis device combines and synthesizes the extracted partial image with the end portion, opposite to the moving vector, of a panorama synthetic image synthesized at this point, i.e., the end portion of the moving direction of an electronic camera.

    摘要: A detection interval in which the rotation status of a stepping motor is divided into a first interval immediately after driving executed by a main driving pulse, a second interval later than the first interval, and a third interval later than the second interval. The driving is executed by a correction driving pulse and the main driving pulse is increased, when a control circuit drives the stepping motor in a driving way different from a driving way at the time of exceeding a predetermined voltage in a case where the voltage of a secondary battery is lowered to be equal to or less than the predetermined voltage and when a rotation detection circuit and a detection time comparison determination circuit detect an induced signal exceeding a first reference threshold voltage in the first interval and the second interval and do not detect the induced signal exceeding a second reference threshold voltage lower than the first reference threshold voltage in the third interval.

    摘要: It is configured to include: a secondary battery as a power supply that supplies power at least to a stepping motor; a rotation detection portion that detects a rotation state of the stepping motor; a control portion that drives the stepping motor by selecting a drive pulse having energy corresponding to the rotation state of the stepping motor from a plurality of drive pulses; and a solar battery that charges the secondary battery. Upon determination that it is possible to rotate the stepping motor by an overcharge indicating drive pulse having predetermined energy, the control portion drives the stepping motor by changing a current drive pulse to an overconsuming drive pulse having larger energy than the overcharge indicating drive pulse. It thus becomes possible to suppress deterioration of a secondary battery caused by overcharge without having to provide a dedicated voltage detection circuit, such as a comparator circuit.
