SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and a user may selectively use one image sensor among two image sensors provided in one handset through one control digital signal processor (DSP). Its purpose is to provide a method for controlling two image sensors within a handset.

According to an aspect of the present invention, there is provided a control method of an image sensor applied to a handset having two image sensors, the method comprising: a first step of receiving an image sensor driving request from a user of the handset; A second step of confirming whether an image sensor to be driven by the user has been designated; A third step of driving the designated image sensor through a control DSP if the image sensor to be driven is designated by the user as a result of the checking of the second step; A fourth step of driving a corresponding image sensor based on preset image sensor driving information if the image sensor to be driven is not designated by the user as a result of the checking of the second step; A fifth step of providing an image obtained from a driving image sensor to a user through a screen display unit of the handset; And a sixth step of capturing an image acquired through the driving image sensor according to a photographing request from the user to obtain image data.

The above-mentioned objects, features and advantages will become more apparent from the following detailed description in conjunction with the accompanying drawings. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is an exemplary configuration diagram of a handset to which the present invention is applied.                     

As shown in FIG. 1, the handset to which the present invention is applied may include a first image sensor 1, 11, a second image sensor 2, 12, a control DSP 13, and a handset operating processor 14. ), A slide open sensing unit 15, and a menu operation unit 16.

In this case, the first image sensor Image Sensor1 or 11 may be a sensor for photographing the other party, and the second image sensor Image Sensor2 or 12 may be a sensor for photographing itself. In addition, the handset operating processor 14 refers to a processor such as the MSM series which is actually released by Qualcomm.

In the present invention, as shown in FIG. 1, two image sensors 11 and 12 are inputted through a user's menu operation unit 16 using one control DSP 13 or a slide open sensing. The first image sensor (Image Sensor 1, 11) or the second image sensor (Image Sensor 2, 12) may be selectively used by reading whether the slide 15 is detected by the unit 15.

In this case, the image sensor selection according to whether the slide open is detected is used in the slide type handset terminal. When the slide is opened, the image sensor mounted on the opposite side of the screen display unit is automatically selected. Automatically select the image sensor mounted on the screen display side. Of course, this may vary depending on the position of the image sensor in the slide-type handset terminal, and even if the slide-type handset terminal can use both image sensors regardless of open and close, as described above, The image sensor can be selected based on the settings of the menu operation.

The present invention as described above will be described collectively based on the configuration shown in FIG. 1.

First, the handset operating processor 14 receives selection information for selecting one image sensor among the two image sensors 11 and 12 through the slide open detection unit 15 and the menu operation unit 16. Then, the handset operating processor 14 drives the corresponding image sensor through the control DSP 13, receives the screen transmitted from the image sensor through the control DSP 13, and provides the user with the screen of the handset. The user can take a picture or leave a video while viewing the screen captured by the selected image sensor.

2A and 2B are flowcharts of one embodiment of a method for controlling two image sensors in one handset according to the present invention.

An embodiment of the method of controlling two image sensors in a handset according to the present invention as described above based on the flow shown in FIG. 2 will be described.

First, a user is requested to drive an image sensor in a handset (201). At this time, two image sensors are provided in one handset.

The handset operating processor, which is requested to drive the image sensor, checks whether the user has received the designation for the image sensor (202). That is, the user checks whether the user specifies the image sensor to be driven while requesting the driving of the image sensor.                     

As a result of checking whether the user has received the designation for the image sensor, when the image sensor to be driven is designated, the handset operating processor determines the image sensor to be designated from the user (203).

As a result of checking whether the user has received the designation of the image sensor, if the image sensor to be driven is not designated, the handset operating processor determines the basic setting to determine whether the slide needs to be opened (204).

As a result of determining whether an open detection of the slide is required, if an open detection of the slide is not necessary, an image sensor set as a default when the image sensor is driven is identified (205).

As a result of determining whether the slide is required to be opened, if it is necessary to detect the open of the slide, it is checked whether an open of the slide is detected (206). In other words, it checks whether the slide is open or closed.

As a result of the inspection, if the slide is in the open state, the image sensor designated to be driven when the slide is opened is grasped (207).

As a result of the inspection, if the slide is in the closed state, the image sensor designated to be driven when the slide is closed is grasped (208).

The handset operating processor drives the image sensor identified through the control DSP (209), and provides an image captured by the driven image sensor through the screen of the handset (210).

When the user checks the image provided through the screen of the handset, an image is requested to be photographed by the user (211). In operation 213, the captured image data is provided to the user. That is, the captured image may be provided through the screen of the handset, stored in a file format at the request of the user, and transferred to another handset or a computer.

Embodiments according to the present invention as described above are described as a slide type handset. Therefore, in a flip or clamshell handset, it is not necessary to open or close the slide, and a corresponding condition may be given according to whether the flip or folder is opened and the position of the image sensor. That is, in the case of a clamshell handset, if one of the image sensors of the handset cannot operate when the folder is closed, the image sensor may be selected depending on whether the folder is opened or closed. Of course, regardless of the shape of the handset, the image sensor driven according to the user's selection may be selected.

The method of the present invention as described above may be implemented as a program and stored in a computer-readable recording medium (CD-ROM, RAM, ROM, floppy disk, hard disk, magneto-optical disk, etc.).

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes are possible in the art without departing from the technical spirit of the present invention. It will be clear to those of ordinary knowledge.

As described above, the present invention has an effect that a user can take an image while directly viewing the counterpart and the user through the screen display unit by using two image sensors provided in one handset.

In addition, the present invention, by driving the image sensor corresponding to the driving of the image sensor in accordance with the opening and closing state of the handset has the effect that the user can efficiently use the image sensor through the handset.
