Details of the digital camera disclosed in the US application, its control device, and its control method will be included in the present specification, the detailed description thereof will be omitted.

The control device 500 of the digital camera may be mounted on the digital camera 200 to control the digital camera 200 to operate the digital camera 200. The control device 500 of the digital camera includes a display panel 25; Touch screen 26; A touch signal input unit 526; It is provided with a control unit.

The image is displayed on the display panel 25. The touch screen 26 is disposed on the display panel 25 and receives a touch input from the outside to generate a touch signal.

The touch signal input unit 526 receives a touch signal. The control unit receives a touch signal through the touch signal input unit 526 and manipulates an image according to the touch signal to give an effect. In this case, the controller 507 may be the digital signal processor 507 of FIG. 3.

For example, when a touch signal is input through the touch signal input unit 526, the micro controller 512 processes the input and is assigned to each touch signal according to a menu or function currently set in the digital signal processor 507. The function can be performed.

In addition, the effect on the image manipulated by the controller 507 may be any one of a change in shape and / or size of the image, out focusing on the image, and color change. However, the present invention is not limited thereto, and the image effect may further include various other image processing for giving an effect by processing the image.

The touch screen 26 may include a touch unit 261 and a touch controller 262. The touch unit 261 may be formed by disposing a two-dimensional resistive film having a light transmittance on the display panel 25. The touch controller 262 may be electrically connected to the touch unit 261 to generate a touch signal indicating that a specific position of the touch unit is touched according to an input from the outside.

The touch screen 26 may be made by a resistance measurement method. In this case, when a specific position on the touch unit 261 is touched, the resistance change position measured by the touch controller 262 may be sensed to recognize the position on the screen as X and Y coordinates. To this end, signals at both ends in the X direction of the touch unit 261 are input through the X- and X + terminals of the touch controller 262, and signals at both ends in the Y direction of the touch unit 261 are input to the touch controller 262. It can be input through the Y- and Y + terminals.

When a specific position of the touch unit 261 is touched, in order to generate a touch signal indicating that a corresponding position of an image displayed on the display panel 25 is touched, the touch screen region and the image region are corresponded to each other. Accordingly, as the image on the touch screen from the outside is manipulated, a corresponding touch signal may be generated.

That is, when an image displayed on the display panel 25 is touched by the user, the touch signal is generated and input to the control unit, for example, the digital signal processor 507 through the touch signal input unit 526, and the corresponding control unit generates the touch signal. The touch signal is interpreted to manipulate the image accordingly.

To this end, first, an effect area to be manipulated may be specified by giving an effect in the corresponding image by a user's input from the outside on the touch screen 26 on which the image is displayed. At this time, according to the image effect selected by the user, the control unit detects a change in the touch signal and gives an image effect to the image to change the image.

An image manipulation of an image displayed on the display panel 25 by receiving a user input through a touch screen by the controller, for example, the digital signal processor 507 may be performed by the control method illustrated in FIG. 4.

In the control device 500 of the digital camera according to the present invention, a user may directly operate on a touch screen to effect an image displayed on a display panel. Thus, the user can conveniently manipulate the image.

When the user presses the wide-zoom button W or telephoto-zoom button T included in the user input unit INP, a corresponding signal is input to the micro controller 512. [

Accordingly, as the micro controller 512 controls the lens driving unit 510, the zoom motor M _Z is driven to move the zoom lens. That is, when the wide-angle zoom button W is depressed, the focal length of the zoom lens is shortened to enlarge the angle of view, and if the telephoto-zoom button T is depressed, the focal length of the zoom lens becomes long and the angle of view becomes narrow.

Meanwhile, in the auto focus mode, the main controller incorporated in the digital signal processor 507 controls the lens driving unit 510 through the micro controller 512 to drive the focus motor M _F. The compensation lens compensates for the overall refractive index and is not driven separately. Reference symbol M _A denotes a motor for driving an aperture (not shown).

In the filter section of the optical system (OPS), an optical low pass filter removes optical noise of a high frequency component. Infra-red cut filter blocks the infrared component of incident light.

The photoelectric conversion unit OEC may include an image pickup device such as a CCD (Charge Coupled Device) or a CMOS (Complementary Metal-Oxide-Semiconductor). The photoelectric conversion unit OEC converts light from the optical system OPS into an electrical analog signal.

The analog-to-digital conversion unit may include a CDS-ADC (Correlation Double Sampler and Analog-to-Digital Converter) The analog-to-digital converter processes the analog signal from the photoelectric converter (OEC), removes the high-frequency noise, adjusts the amplitude, and converts the analog signal into a digital signal. Here, the digital signal processor 507 controls the timing circuit 502 to control the operations of the photoelectric conversion unit (OEC) and the analog-digital conversion unit 501.

The real-time clock 503 provides time information to the digital signal processor 507. The digital signal processor 507 processes the digital signal from the CDS-ADC element 501 to generate a digital image signal classified into luminance and chroma signals.

A self-timer lamp, an auto-focus lamp, a mode indicating lamp, a flash standby lamp, and the like are provided in the light emitting portion (LAMP) driven by the microcontroller 512 under the control of the main controller incorporated in the digital signal processor 507 . The user input unit INP may include a direction button 21, a wide-angle zoom button W, a tele-zoom button T, and the like.

A digital image signal from the digital signal processor 507 is temporarily stored in a DRAM (Dynamic Random Access Memory) 504. The EEPROM (Electrically Erasable and Programmable Read Only Memory) 505 stores algorithms and setting data such as a boot program and a key input program required for the operation of the digital signal processor 507. In the memory card interface 506, a user's memory card is detached.

The digital image signal from the digital signal processor 507 is input to the display panel driver 514, which causes the image to be displayed on the display panel 25.

On the other hand, the digital image signal from the digital signal processor 507 can be transmitted by serial communication through a USB (Universal Serial Bus) connection 31a or RS232C interface 508 and its connection 31b, 509 and the video output unit 31c as video signals. Here, the digital signal processor 507 may incorporate a micro controller therein.

The audio processor 513 outputs the audio signal from the microphone MIC to the digital signal processor 507 or the speaker SP and outputs the audio signal from the digital signal processor 507 to the speaker SP .

On the other hand, the control device 500 of the digital camera may be provided with a touch signal input unit 526. The user command from the outside may be input through the touch signal input unit 526.

In this case, a touch signal input through the touch screen 26 of FIG. 1 may be input to the touch signal input unit 526. When a touch signal is input through the touch signal input unit 526, the micro controller 512 processes the input to perform a function according to the input. In this case, a function allocated to each touch signal may be performed according to a menu or function currently set in the digital signal processor 507.
