Video camera having display for displaying movement speed and hand wobble

Abstract

A video camera that displays movement speed and hand wobble to allow a photographer to perform a stable photographing operation. The video camera detects up and down movement and left and right movement. The video camera discerns a detection signal as hand wobble when the detection signal is a periodic waveform having a predetermined frequency component, and discerns the detection signal as camera movement when the detection signal is a waveform having a constant amplitude without a frequency component. The video camera discriminates whether the detected hand wobble and movement speed are equal or greater than a reference value and a reference speed, respectively, and displays the hand wobble and movement speed quantitatively on a monitor, such as an electronic viewfinder. The video camera also displays a warning message to make the photographer recognize a current photographing state.
