Method for control of camera module based on physiological signal

An apparatus comprising:

• an image sensor disposed in a first surface of the apparatus;
• a heart rate monitor (HRM) sensor disposed in a second surface of the apparatus;
• and
• a processor adapted to:
• execute a camera application;
• activate the HRM sensor based on the execution of the camera application;
• receive an input signal via the HRM sensor;
• identify, based at least in part on the input signal, a movement of a user or an object external to the apparatus;
• and
• capture an image using the image sensor based at least in part on a determination that the movement satisfies a specified condition.

An apparatus comprising:

• a plurality of image sensors to capture an image, the plurality of image sensors including a first image sensor and a second image sensor;
• a touchscreen display;
• a biometric sensor to receive an input signal related to the capturing;
• and
• a processor adapted to:
• present, via the touchscreen display, a preview obtained from at least one of the first image sensor and the second image sensor;
• identify whether the preview is obtained using the first image sensor or the second image sensor;
• activate the biometric sensor if the preview is obtained using the first image sensor;
• and
• refrain from activating the biometric sensor if the preview is obtained using the second image sensor.
