Benefits of technology
The patent is about a device that can measure how long a shutter is exposed to light. This helps to correct any errors in the timing of the shutter.
Problems solved by technology
However, the divided images recorded in this way are not recorded from one scene with the same exposure.
Therefore, when an object moves at a high speed, or in a situation with rapidly changing exposure such as instantaneous light, part-specific exposures may cause a separated area in an output image, or limit the highest shutter speed when divided images of strobe photography using instantaneous light are synchronized.
However, it is difficult for the travel of the front curtain and the rear curtain having mechanical structures to coincide completely with high-speed travel as described above, and there is a desire for a control method which complements the travel.

An electronic apparatus is disclosed. The electronic apparatus includes: an imaging device which converts light into an image signal; a lens unit positioned in front of the imaging device to form an image on the imaging device from light incident from an object; a shutter unit interposed between the lens unit and the imaging device to expose the imaging device to the light incident from the object based on a predetermined exposure time and that includes a shutter curtain that regulates the light incident from the object; and a measurement unit which measures an actual exposure time of the shutter unit. The measurement unit is positioned behind the shutter curtain and includes a light-receiving sensor which receives light incident on the measurement unit from the light incident from the object other than the light of the effective image area incident on the imaging device.
Description
CROSS-REFERENCE TO RELATED PATENT APPLICATIONS[0001]This application claims the priority benefit of Korean Patent Application No. 10-2013-0143251, filed on Nov. 22, 2013, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein in its entirety by reference.BACKGROUND[0002]1. Field[0003]One or more embodiments of the present disclosure relate to an electronic apparatus capable of measuring an actual exposure time of a shutter unit.[0004]2. Related Art[0005]Lately, digital single-lens reflex (DSLR) cameras, which enable expert-level photography, are coming into wide use.[0006]In a DSLR camera, which sends the image of an object to a viewfinder, and sends light to an imaging device for taking a picture through a single lens, a focal plane shutter is positioned in front of the imaging device to regulate the exposure time of the imaging device. The focal plane shutter is a mechanical shutter including two curtains called a front curtain and a rear curtai...
