1. An electronic apparatus, comprising:
- a lighting device that emits visible light;
an imaging device that acquires an image of a subject; and
a photographing system comprising;
an adjusting module that adjusts a direction of the visible light to make the light pass next to the subject;
a recognizing module that recognizes a bright spot of light formed when the subject blocks the visible light with a body part of the subject, and determines states of the bright spot of light by analyzing the image of the subject, the states of the bright spot of light determined by periods of time and frequencies of the blocking of the visible light by the subject; and
a controlling module that controls the imaging device to execute a different photographing function for each state of the bright spot of light,wherein the recognizing module determines that the bright spot of light is continuous shining when the bright spot of light lasts more than one second, and determines that the bright spot of light is flashing when the bright spot of light lasts less than one second, andwherein the states of the bright spot of light comprise at least a continuous shining state in which the bright spot of light lasts more than one second, a first flashing state in which the bright spot of light flashes once within a predetermined time interval, and a second flashing state in which the bright spot of light flashes twice within the predetermined time interval.

Abstract
An electronic apparatus includes a lighting device, an imaging device, and a photographing system. The lighting device emits visible light. The imaging device views a subject. Prior to an image capture, the photographing system recognizes blocking of a bright light by a subject'"'"'s hand or arm, where the bright spot of light and the photographing system controls the bright light to switch off and immediately capture an image.

7. A photographing method being performed by execution of computer readable program code by a processor of an electronic apparatus, the method comprising:
-
adjusting a direction of visible light emitted by a lighting device of the electronic apparatus to make the visible light pass next to a subject; acquiring an image of the subject with an image device of the electronic apparatus; analyzing the image of the subject to recognize a bright spot of light formed when the subject blocks the visible light with a body part of the subject; determining states of the bright spot of light by measuring periods of time and frequencies of the blocking of the visible light by the subject; and executing a different photographing function of the imaging device for each state of the bright spot of light, wherein the bright spot of light is determined to be continuous shining when the bright spot of light lasts more than one second, and the bright spot of light is determined to be flashing when the bright spot of light lasts less than one second, and wherein the states of the bright spot of light comprises at least a continuous shining state in which the bright spot of light lasts more than one second, a first flashing state in which the bright spot of light flashes once within a predetermined time interval, and a second flashing state in which the bright spot of light flashes twice within the predetermined time interval. - View Dependent Claims (8, 9, 10, 11)
