In an automatic continuous focusing device, two detected images of an object formed by a distance detection optical system with a relative distance therebetween associated with the object distance are scanned, the obtained scanning signals are quantized to generate quantized picture element data, the relative distance between the two detected images is detected on the basis of the quantized picture element data, and an imaging optical system to be focused on the object is controlled according to the detection result. The device also provides for invalida...
An automatic focusing device comprising: sensing means for sensing an image of an object and for generating a plurality of signals therefrom; control means for generating a control signal; focusing means for focusing an optical system on the basis of the plurality of signals from said sensing means, said focusing means focusing the optical system only when said focusing means continuously detects the control signal for a predetermined time period; and inhibiting means having a detection period shorter than the predetermined time period, said inhibiting m...
