Abstract: An image processing device performs projection conversion that makes an image captured of an object to be recognized closer to a normal image captured from front of the object to be recognized based on a correlation between: a pre-specified plurality of feature ranges dispersed within a range of the object to be recognized; and a plurality of feature ranges designated based on the dispersion in the image.

Abstract: A tape drive control system for a pinch roller-less type tape recorder in which tape drive is implemented by frictional force between the capstan and tape. A mode instruction circuit determines the operational mode of a capstan motor drive circuit which operates a capstan motor which in turn rotates the conveying capstan. Tape run detection means detects the actual tape condition. The mode instruction circuit operates both in response to outputs of the tape run detection means and to switch inputs to control the operational mode of the capstan drive.

Abstract: A friction force drive capstan tape recorder having movable arms to tension a tape between an idler and a drive capstan. The displacement of the arms is sensed to provide an input signal to a control circuit to vary the rotational torque of the take-up reel motor. This closed loop system allows constant tension to be maintained on the tape and the sensing of the end of the tape. Freely rotatable tape shifters are provided to minimize tension loss. The movable arms are outwardly displaceable to facilitate tape loading by means of a gear train coupled to the operating lever. At the same time the rollers are displaced to facilitate tape handling. A switch may be coupled to the operating lever to provide power to the system or cut it off.
