Abstract: A pulse motor control device includes a drive pulse generator configured to generate a drive pulse in accordance with a set cycle, a pulse motor driver configured to generate an excitation current of a pattern corresponding to the number of division per one step of a pulse motor based on the drive pulse supplied from the drive pulse generator, the number of division being set in the pulse motor driver, the pulse motor driver supplying the excitation current to the pulse motor to thereby drive the pulse motor based on micro-step driving, and a controller configured to set the cycle in the drive pulse generator every time the drive pulse is supplied from the drive pulse generator.

Abstract: A remote image-pickup system includes a camera device including an image-pickup unit for capturing an image of a subject and generating picture signals and a card slot; and a plurality of types of card substrates which are selectively inserted into the card slot and which convert the format of the picture signals so as to output the converted signals to an external device. By inserting different card substrates into the card slot, a plurality of formats of picture signals can be output from the camera device. Accordingly, the format of the picture signals output from the camera device can be flexibly expanded. Further, since many circuits for converting the picture signals need not be incorporated into the camera device, an increase in the size and price of the camera device can be prevented.
