- event information is acquired from the sub-microcomputer 46 (S177), and it is detected whether or not there is a button input event indicating that the button has been operated (S179).
- button input event it is detected whether or not the sound input from the microphone 40 has a predetermined level or more after cutting the high-frequency component (S181).
- step S183 When a sound meeting the condition is detected in step S181, a photographing process is performed (S183), and the process returns to the previous stage of step S177. If no sound matching the conditions is detected in step S181, the process returns to the previous step of step S177 without performing the photographing process.
- the sound control mode does not end even when the photographing processing is performed.
- the photographing process in step S183 indicates a process in which the pre-process of the image recording process and the image recording process in the normal photographing mode are combined.
- step S179 if it is detected in step S179 that a button input event is present, if the event is caused by the operation of the shutter button 52a, the sound detection function in the main microcomputer 42 is disabled. Then, the sound control mode is terminated (S185, S187). If it is detected in step S185 that the button input event is not caused by the operation of the shutter button 52a, an operation sound B composed of only the high frequency component is generated (S189) Then, processing corresponding to the button input event detected in step S179 is performed (S191), and the process returns to the previous stage of step S177. Since the operation sound B is composed of only the high-frequency components, it is excluded from the detection conditions in step S181. Therefore, the sound control function does not operate with the operation sound B.
- the operation sound is changed in a state where the sound control mode is set, thereby avoiding a malfunction caused by a sound emitted by using the operation button.
- the sound detection function in the main microcomputer 42 is activated only by operating the sound control mode setting button 52b without operating the shutter button 52a. You may make it dagger.
- the button necessary to activate the sound detection function after operating the sound control mode setting button 52b is not limited to the shutter button 52a.
- the control by sound is not limited to the start of the photographing operation, and a plurality of operation controls corresponding to a plurality of sounds may be performed by using a voice recognition unit.
- the present invention is not limited to a digital still camera, but can be implemented with any electronic device controlled by sound.
