In an apparatus for detecting a human face from an input image, candidate areas for an eye and candidate areas for an interval between eyes are detected from the image, an area of the interval between eyes is determined from the positional relationship between the candidate areas for an eye and candidate area for an interval between eyes, and a face area is determined so that the face area includes the area of the interval between eyes.

A panel member control system for controlling a panel member includes a motor, a rotation detecting means, and a pinching detecting means. The rotation detecting means detects a rotational speed of the motor. The pinching detecting means detects an occurrence of pinching of an object by the panel member when a pinching indicative value exceeds a pinching determination threshold. The pinching detecting means includes a disturbance detecting means and a correcting means. The disturbance detecting means determines whether the motor is in a disturbed state based on a change in the rotational speed. The correcting means corrects the pinching determination threshold in view of a result of the determination made by the disturbance detecting means.

To provide a control system for an opening / closing body for a vehicle, which can suppress the misdetection of pinching, even if it is caused by a hardly reproducible phenomenon. This control system for the opening / closing body for the vehicle comprises: the openable / closable opening / closing body which is installed in the opening of the vehicle; a driving means 4 for supplying power for opening / closing the opening / closing body; a load detecting means 8 for detecting an operation load of the driving means 4; and a control means 7 for controlling the driving means 4 by grasping a position of the opening / closing body. During the operation of the opening / closing body, the control means 7 performs the detection of the pinching, in which it is determined whether or not the operation load of the driving means 4, detected by the load detecting means 8, exceeds a predetermined threshold. When it is determined that predetermined conditions based on predetermined operations are satisfied, the pinching is detected by means of a second threshold smaller than the predetermined threshold.

A first state quantity and a second state quantity of a valve stem dislocation are calculated, and a ratio of the first state quantity and the second state quantity is calculated as a first stick-slip indicator SSpv in a first stick-slip indicator calculating portion (14). A third state quantity and a fourth state quantity of a control instruction value of a valve stem dislocation are calculated, and a ratio of the third state quantity and the fourth state quantity is calculated as a second stick-slip indicator SSsp in a second stick-slip indicator calculating portion. With a threshold value as Th, a first constant as alpha, and a second constant as beta, a fault evaluating portion concludes that a stick-slip has occurred when the conditional expression''SSpv>Th AND SSpv>alphaSSsp+beta''is satisfied.

A device includes a first change detection unit which detects a change region distribution based on the texture information; a second change detection unit which detects a change region distribution based on a background differential method; a texture detection unit, a change-detection-unit weighting storage unit, and a change detection result integration unit, wherein while applying a firm texture differential method to the illumination change as much as possible, a detection unit based on a background differential method is applied to a region to which the texture differential method is not favorably applicable.
