Patent ID: 7586535

Claim:
An image capturing device in which auto-focusing process is initiated by half-pressing of a shutter button, and image capturing process is initiated by full-pressing of a shutter button, comprising: a detection circuit for detecting an operational interval T between the half-press operation and the full-press operation; a parameter acquiring circuit which acquires image capturing parameters; a control circuit for continuing the same auto-focus processing and initiating image capturing after completion of the same auto-focus processing when the operational interval is longer than a predetermined threshold interval T 0 ; for stopping the same auto-focus processing and initiating instantly image capture when the operational interval is shorter than the threshold interval T 0 , and when the image capturing parameters satisfy predetermined conditions; and for continuing the same auto-focus processing and initiating image capturing after completion of the same auto-focusing processing when the image capturing parameters fall to satisfy predetermined conditions and when the operational interval is shorter than the threshold interval T 0 .
