Lifelog camera and method of controlling same using voice triggers

A camera that is configured to capture digital image data the digital image data including at least one of a digital image or a video, comprising:

• a control circuit configured to
• capture digital image data without user input that commands the capturing of the digital image data,
• detect a sound-based trigger in an audio signal output by a microphone present at the camera, the sound-based trigger indicative of activity of the user or another person near the user,
• determine at least one of a type of the sound-based trigger or an intensity of the sound-based trigger, wherein prior to capturing the digital image data a number of images to be captured or a determination to capture video instead of or in addition to the capture of one or more images is based on the determined type of the detected sound-based trigger or the determined intensity of the detected sound-based trigger;
• a camera module that captures the digital image data under the control of the control circuit in response to the detection of the sound-based trigger and at least one of the determined type of the sound-based trigger or the determined intensity of the sound-based trigger;
• and
• a memory in which the digital image is stored.

A method of capturing and storing digital image data, the digital image data including at least one of a digital image or a video, the method comprising:

• using a camera that is configured to capture the digital image data without user input that commands the capturing of the digital image data;
• capturing the digital image data with a camera module of the camera, the capturing triggered by a time schedule for capturing images;
• analyzing an audio signal output by a microphone present at the camera for a sound-based trigger indicative of activity of the user or another person near the user and occurring within a predetermined amount of time before or within a predetermined amount of time after the capturing of the digital image data;
• determining at least one of a type of the sound-based trigger or an intensity of the sound-based trigger;
• and
• storing the digital image data in an image store of a memory for later displaying or transfer to an electronic device separate from the camera if detection of the sound-based trigger is made, wherein prior to capturing the digital image data a number of images to be captured or a determination to capture video instead of or in addition to the capture of one or more images is based on the determined type of the detected sound-based trigger or the determined intensity of the detected sound-based trigger, else not retaining the digital image in the camera for later displaying or transfer to an electronic device separate from the camera.
