Description

A cell phone with ring flash < RTI ID = 0.0 >

The present invention relates to a mobile phone having a ring flash for preventing light from being reflected on a subject or causing a shadow to appear on a subject when a camera function is operated.

In recent years, mobile phones have been providing various functions to users in a form combined with computers. Among the various functions, the most frequently used function of the user is the camera function. The camera function is easy to carry by attaching a miniature digital camera to the mobile phone, and the user can freely take a picture without any special skill. However, when a flash attached to a mobile phone is used for taking a picture, there is a problem that light is reflected by the subject due to the fixed light source, shadows are formed around the subject, and the light metering can not be corrected.

Korea public utility model 20-2011-0009084 (published on September 23, 2011) "LED ring light device for DSLR camera" Korean Registered Patent No. 10-1151698 (Registered May 26, 2012) "Ring Light for Camera"

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide an image pickup apparatus capable of preventing a subject from being reflected by focused light, The present invention relates to a mobile phone having a ring-shaped flash capable of finding an exposure value.

According to an aspect of the present invention, there is provided a mobile phone including a camera for photographing a subject according to an embodiment of the present invention. The mobile phone includes a ring- Flash.

And a main flash located in the periphery of the camera and irradiating a focused light to the subject.

And a photometry measuring unit for measuring photometry of the subject.

The light measuring unit may be an illuminance sensor for measuring the illuminance and determining the light metering.

The light measuring unit may analyze the image photographed by the camera to determine the light metering.

The ring-shaped flash may be divided into a plurality of light beams to illuminate the center of the camera so as to irradiate light only to the portion corresponding to the measured light.

According to the present invention, it is possible to prevent a light source from being condensed on a subject by providing a ring-shaped flash, and to prevent light from being reflected or shadows of a subject being condensed on the subject.

Further, the photometric amount of the subject can be measured by the photometric measurement unit, and the light emission mode of the ring flash can be set, so that the photograph can be photographed by finding an appropriate exposure value.

1 is a rear view illustrating a mobile phone having a ring flash according to an embodiment of the present invention.
2 is a rear view schematically showing a light emitting state of a ring flash constituting a cellular phone having a ring flash according to an embodiment of the present invention.
3 is a rear view schematically showing another light emitting state of a ring flash constituting a cellular phone having a ring flash according to an embodiment of the present invention.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

Referring to FIG. 1, a mobile phone 100 having a ring-shaped flash according to an embodiment of the present invention may include a camera 110.

The camera 110 can photograph a subject to be photographed by the user.

On the other hand, the camera 110 may be provided on one or both of the front and rear of the cellular phone, and the camera 110 may be a known ccd sensor or a cmos sensor.

The mobile phone 100 having the ring flash according to the embodiment of the present invention may include the main flash 120. [

The main flash 120 can irradiate a subject with concentrated light.

On the other hand, the main flash 120 may be provided around the camera, and may emit intense light to a subject by emitting strong light to the subject during photographing.

Further, the main flash 120 may be turned on or off by the user.

Referring to FIGS. 1 to 3, a cellular phone 100 having a ring-shaped flash according to an embodiment of the present invention may include a ring-shaped flash 130.

The ring-shaped flash 130 can illuminate the light to reduce the shadow of the subject.

On the other hand, the ring-shaped flash 130 may be formed in the shape of a ring, and may be formed around the camera 110. [

In addition, the ring-shaped flash 130 may be provided around the camera 110 around the camera 110, or may be provided around the cell phone 100, so that light is not concentrated on the subject and shadowing of the subject is reduced Light can be irradiated.

The ring-shaped flash 130 may be divided into a plurality of parts, and may partially illuminate the light based on the information received from the photometric measurement unit 140 described later.

For example, when the photometry measured by the photometry measuring unit 140 is less right than the left side of the subject, the ring-shaped flash 130 can illuminate only the right side of the subject. On the contrary, The ring-shaped flash 130 can illuminate only the left side of the subject. When the photometry is less than the upper portion of the subject, the ring-shaped flash 130 can irradiate only the lower portion of the subject, and when the photometry is small at the edge of the subject, the ring- have.

Therefore, the ring-shaped flash 130 can emit light for the entire light emission, the light emission upon photographing, the side light emission, and the flashing of the ring-shaped flash 130 by the information measured by the photometric measurement unit 140 or by the user's selection of the light emission mode .

Here, the ring-shaped flash 130 may be implemented with an LED.

The mobile phone 100 having the ring flash according to the embodiment of the present invention may include the photometric measurement unit 140.

The metering measurement unit 140 can measure the metering of the subject.

Meanwhile, the photometric measurement unit 140 may be provided around the camera 110, may measure photometry by analyzing an image photographed by the camera 110, and may be implemented with an illumination sensor.

When the metering light is measured, the metering unit 140 transmits the measured information to a control unit (not shown), and the control unit (not shown) controls the ring- Can be controlled.

The cellular phone 100 having the ring flash according to the embodiment of the present invention has the camera 110 in the cellular phone 100 and the main flash 120 and the photometry part 140, and then installs a ring flash 130 around the periphery of the cell phone 100 or around the camera 110.

Then, after the user holds the mobile phone 100 so that the camera 110 faces the subject, the user turns on the main flash 120 to illuminate the subject with a focused light according to the surrounding environment, (130).

At this time, when the ring-shaped flash 130 is used, the user selects the light emitting mode of the ring-shaped flash 130, or the metering measurement unit 140 measures the light amount of the subject and transmits the measured information to the control unit , The control unit (not shown) may select the light emitting mode of the ring-shaped flash 130 to drive the ring-shaped flash 130 to photograph the subject.

Therefore, it is possible to prevent the light source from being condensed on the subject by being provided with the ring-shaped flash 130, and it is possible to prevent light from being reflected or shadows of the subject being condensed on the subject.

In addition, since the photometric amount of the subject can be measured by the photometric measurement unit 140, the light emission mode of the ring-shaped flash unit 130 can be set, so that a photograph can be photographed by finding an appropriate exposure value.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, And all changes and modifications to the scope of the invention.
