Abstract

A wearable apparatus and method are provided for capturing image data. In one implementation, a wearable apparatus for capturing image data is provided. The wearable apparatus includes at least one image sensor for capturing image data of an environment of a user, wherein a field of view of the image sensor includes a chin of the user. The wearable apparatus includes two or more microphones, and an attachment mechanism configured to enable the image sensor and microphones to be worn by the user. The wearable apparatus includes a processing device programmed to capture at least one image, identify the chin of the user to obtain a location of the chin, select a microphone from the two or more microphones based on the location, process input from the selected microphone using a first processing scheme, and process input from a microphone that is not selected using a second processing scheme.

Claims

1. A wearable apparatus for capturing image data, the wearable apparatus comprising:

at least one image sensor for capturing image data of an environment of a user, wherein a field of view of the image sensor includes at least a portion of a chin of the user;

at least one microphone;

an attachment mechanism configured to attach the at least one image sensor and the at least one microphone to the user; and

at least one processing device programmed to;

identify a chin of the user in the image data to obtain a direction the chin of the user is facing with respect to a body of the user;

based on the direction the chin of the user is facing, activate the at least one microphone to record sound in the direction the chin is facing;

identify a direction of sound received by the at least one microphone; and

after identifying the direction of the sound, adjust a pixel resolution for capturing subsequent image data at a higher resolution.

2. The wearable apparatus of claim 1, wherein the field of view of the at least one image sensor is more than 180°

.

3. The wearable apparatus of claim 1, wherein the field of view of the at least one image sensor is more than 300°

.

4. The wearable apparatus of claim 1, further comprising at least one solar cell configured to provide power to the image sensor.

5. The wearable apparatus of claim 4, wherein the at least one solar cell is included in a capturing unit that includes the image sensor.

6. The wearable apparatus of claim 1, further comprising a power unit including an energy storage device configured to store energy derived from movements of the user.

7. The wearable apparatus of claim 6, wherein the stored energy is used to power the image sensor.

8. The wearable apparatus of claim 1, wherein the at least one processing device is further programmed to cause the subsequent image data to be stored.

9. The wearable apparatus of claim 1, wherein the at least one processing device is further programmed to transmit the subsequent image data to an external device.

10. A method comprising:

identifying a chin of a user of a wearable apparatus in image data to obtain a direction the chin of the user is facing with respect to a body of the user;

based on the direction the chin of the user is facing, activating at least one microphone of the wearable apparatus to record sound in the direction the chin is facing;

identifying a direction of sound received by the at least one microphone; and

after identifying the direction of the sound, adjusting a pixel resolution for capturing subsequent image data at a higher resolution.

11. The method of claim 10, further comprising causing the subsequent image data to be stored.

12. A non-transitory computer readable medium storing instructions for carrying out the method of claim 10.
