发明名称 IMAGE BLUR CORRECTION LENS DEVICE AND CORRECTION METHOD THEREFOR
摘要 PROBLEM TO BE SOLVED: To improve vibration restraining effects, by providing a tripod with an operation angle detecting means and highly accurately detecting vibration. SOLUTION: In step S2, panning positional data P, outputted from a panning detection means disposed on the tripod, are inputted. In step S3, a different positional change quantityΔP from a set reference position P0 is calculated. In step S9, determination is made whether the positional change quantityΔP is equal to or larger than a given threshold. This process determines whether the operator of the tripod 10 has deliberately performed a panning operation. When the positional change quantityΔP is smaller than the threshold, it is considered as vibration data, and then an HPF process in step S10 and a phase compensation process in step S11 are performed. In step S12, an adjustment coefficient is extracted by using a focal distance obtained using a focal distance detecting means and using a table stored in a CPU. By multiplying the coefficient with the vibration data created by the time of step S11, control data for an image blur correction lens group are generated. Based on the control data, the correction lens control processing of step S7 to step S14 is repeated. COPYRIGHT: (C)2007,JPO&INPIT
