Description

本発明は、デジタルカメラなどの撮像装置における操作性を改善する検出装置及び振り操作検出方法及びプログラムに関するものである。 The present invention relates to a detection apparatus, a swing operation detection method, and a program for improving operability in an imaging apparatus such as a digital camera.

また、加速度を検出することが可能なカメラにおいて、従来の本動作の波形を検出した後にカメラを振る本動作をした時に割り当てられた機能を実行するのでは、振った時と機能の実行時との間にタイムラグが生じる。このタイムラグによって、撮像装置の直感的な操作方法を実現しようとするにも関らず、使用しにくいと言った課題があった。
本発明は、上記の問題点に鑑みてなされたものであり、実際の操作方法に応じた加速度波形の特徴を用いて検出を行うことにより、高い検出精度で所定の動作を検出可能とし、直感的な操作方法を実現する検出装置及び振り操作検出方法及びプログラムを提供するものである。 In addition, in a camera capable of detecting acceleration, the function assigned when performing the main operation of shaking the camera after detecting the waveform of the conventional main operation is executed when the camera is shaken and when the function is executed. There is a time lag between Due to this time lag, there has been a problem that it is difficult to use although it is intended to realize an intuitive operation method of the imaging apparatus.
The present invention has been made in view of the above-described problems. By performing detection using the characteristics of the acceleration waveform according to the actual operation method, it is possible to detect a predetermined operation with high detection accuracy, and intuitively. The present invention provides a detection apparatus, a swing operation detection method, and a program that realize a typical operation method.
