4 to 7 schematically illustrate rotation directions and folding modes of the LCD display device according to the display device modes. FIG. 10 is a flowchart schematically illustrating an embodiment of a method of controlling a photographing apparatus to set a power mode according to a display apparatus mode in the digital camera of FIGS. 1 to 8.

Referring to the drawings, a digital camera as an embodiment of a photographing apparatus equipped with a rotatable display device according to the present invention is a digital camera 1 shown in Figs. 1 to 2, and a rotatable display on its body portion 1a. The device is equipped with a color LCD panel 35. In this case, the color LCD panel 35 is rotatable and foldable, as shown in FIGS. 4 to 7, to facilitate shooting at various angles and to allow self-shooting.

In particular, the power supply mode may be changed according to the rotation direction of the color LCD panel 35 and the display device mode by the folding mode. That is, the user detects a specific display mode in which the user does not use the camera temporarily, and enables the power mode to enter the power saving mode, thereby powering the camera from the new power off state at the moment when the user wants to shoot. Allows you to perform shooting immediately, without having to wait for the time to start up in the ON state.

Therefore, when the camera is not in use temporarily, the power is cut off except for the part required for the camera to be turned on, and the power is saved. It is possible to allow the user to take a picture without missing an instant image.

In this case, the display device mode may be a first mode (FIG. 4), a second mode (FIG. 5), a third mode (FIG. 6), and a fourth mode according to the rotation direction and the folding mode of the color LCD panel 35. 7).

The first mode (Fig. 4) is a mode in which the display surface of the color LCD panel 35 faces the body portion 1a and is closed. The second mode (Fig. 5) is a mode in which the display surface of the color LCD panel 35 faces in the opposite direction to the body portion 1a and is closed. The third mode (Fig. 6) is a mode in which the display surface of the color LCD panel 35 is open toward the body portion 1a. The fourth mode (Fig. 7) is a mode in which the display surface of the color LCD panel 35 is open facing the opposite direction of the body portion 1a.

In addition, the power mode may be a power saving mode and a normal mode, the power saving mode is a mode that is operated to save power, the normal mode is a mode that does not perform a separate power saving operation.

At this time, when the power mode is a power saving mode, it is preferable to operate to cut off the power applied to other devices except the memory control unit and the main control unit provided in the control device (see FIG. 8) of the digital camera.

Particularly, in the present embodiment, when the display device mode is the first mode, the user detects the digital camera as a mode that is not temporarily used, and switches the power mode to the power saving mode, saving power and allowing the user to take pictures. If you want to do it, you can immediately switch the power mode to the normal shooting mode.

In this case, when the display device mode is switched to one of the second mode, the third mode, and the fourth mode, it is preferable to sense that the user wants to take a picture.

According to the photographing apparatus control method 810 of setting the power mode according to the display device mode in the digital camera according to the present invention, determining the display device mode (step 811) and setting the power mode to the power saving mode (step 812). And setting the power mode to the normal mode (step 813).

In the determining of the display device mode (step 811), the display device mode may be determined by detecting an operation state of the color LCD panel 35 by the user. That is, it is preferable to determine the display device mode by detecting the rotation state of the color LCD panel 35 and whether it is folded. In this case, the display device mode determination according to the user's operation of the color LCD panel 35 is performed according to the operation state of the color LCD panel 35 as shown in FIGS. 4 to 7. It may be one of the fourth modes.

8 is a view showing the overall configuration including a control device of the digital camera of FIGS. 1 to 7, the overall configuration and operation of the digital camera 1 of FIG. 1 will be described.

The transparent barrier 13 for preventing foreign matter from adhering to the optical system OPS is driven by the barrier motor M _B to be opened or closed. The optical system OPS including the lens unit and the filter unit optically processes light from a subject. The lens unit of the optical system OPS includes a zoom lens, a focus lens, and a compensation lens.

When the user presses the wide angle-zoom button 39w or the telephoto-zoom button 39t included in the user input unit INP, a corresponding signal is input to the microcontroller 512. Accordingly, as the microcontroller 512 controls the lens driver 510, the zoom motor M _Z is driven to move the zoom lens. That is, when the wide-angle zoom button 39W is pressed, the focal length of the zoom lens is shortened to widen the angle of view, and when the telephoto-zoom button 39T is pressed, the focus of the zoom lens is pressed. The longer the length, the narrower the angle of view. Here, since the position of the focus lens is adjusted while the position of the zoom lens is set, the angle of view is hardly influenced by the position of the focus lens.

Meanwhile, in the auto focus mode, the focus motor M _F is driven by the main controller embedded in the digital signal processor 507 controlling the lens driver 510 through the microcontroller 512. As a result, the focus lens is moved from the front to the rear, and in this process, the position of the focus lens where the high frequency component of the image signal is the largest, for example, the number of driving steps of the focus motor M _F is set.

The compensation lens compensates for the overall refractive index and is not driven separately. Reference numeral 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 high frequency components. Infra-Red cut filter cuts the infrared component of the incident light.

A photoelectric conversion unit (OEC) of a charge coupled device (CCD) or a complementary metal-oxide-semiconductor (CMOS) converts light from an optical system (OPS) into an electrical analog signal. Here, the digital signal processor 507 controls the timing circuit 502 to control the operations of the photoelectric converter OEC and the analog-digital converter 501. The CDS-ADC (Correlation Double Sampler and Analog-to-Digital Converter) element 501 as an analog-to-digital converter processes the analog signal from the photoelectric converter (OEC), removes the high frequency noise, and adjusts the amplitude. After that, it is converted into a digital signal.

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.

The self-timer lamp 11, the auto-focus lamp 33, and the mode indicating lamp are provided to the light emitting part LAMP driven by the microcontroller 512 under the control of the main controller embedded in the digital signal processor 507. 14L and flash standby lamp 34 are included. In the user input unit INP, the shutter button 13, the mode dial 14, the function buttons 15, the monitor button 32, the manual focusing / delete button 36, the manual adjustment / playback button 37 ), A wide-angle zoom button 39W, a telephoto-zoom button 39T, and the like.

The digital image signal from the digital signal processor 507 is temporarily stored in the DRAM (Dynamic Random Access Memory) 504. The EEPROM (Electrically Erasable and Programmable Read Only Memory) 505 stores algorithms and setting data necessary 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 LCD driver 514, whereby the image is displayed on the color LCD panel 35.

On the other hand, the digital image signal from the digital signal processor 507 can be transmitted by serial communication via a universal serial bus (USB) connection portion 21a or an RS232C interface 508 and the connection portion 21b, and a video filter ( 509 and the video output unit 21c may be transmitted as a video signal. Here, the digital signal processor 507 incorporates a microcontroller 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 microcontroller 512 drives the flash 12 by controlling the operation of the flash controller 511 according to the signal from the flash-light amount sensor 19.

There may be various methods for implementing the power mode according to the present invention. In the present embodiment, the power mode may include a power saving mode and a normal mode. The power saving mode is a mode that operates to save power, and the general mode is a mode in which an operation for additional power saving is not performed.

In particular, the power saving mode is a mode for minimizing power usage without performing a series of processes performed by the initial startup of the camera. The power saving mode is applied to other devices except for a memory controller and a main controller of the digital camera. It is desirable to operate to cut off the power supply.

In the exemplary embodiment shown in the drawing, the power saving mode may be implemented by maintaining a state in which power is applied only to the digital signal processor 507 and the memory control unit as main controllers and cutting off power applied to other components. In this case, the memory controller may be one of the DRAM 504, the EEPROM 505, and the memory card interface (MCI) 506.

9 is a flowchart illustrating a photographing algorithm performed by the digital camera of FIGS. 1 to 7.

Referring to the drawing, the shutter button 13 included in the user input unit INP has a two-stage structure. In other words, after the user operates the wide-angle zoom button 39W and the tele-zoom button 39T, the S1 signal from the shutter button 13 is turned on by pressing the shutter button 13 only one step, and 2 When the button is pressed all the way, the S2 signal from the shutter button 13 is turned on. Therefore, the photographing algorithm of FIG. 8 starts when the user presses the shutter button 13 to one step (step S701). Here, the current position of the zoom lens is already set.

Next, the remaining amount of the memory card is checked (step 702), and it is checked whether or not the capacity of the digital video signal can be recorded (step 703). If it is not a recordable capacity, it is indicated that the capacity of the memory card is insufficient (step 704). In the case of a recordable capacity, the following steps are performed.

First, an automatic white balance (AWB) mode is performed according to the set photographing information to set relevant parameters (step 705). Next, an automatic exposure (AE) mode is performed in accordance with the set photographing information so that the exposure amount for the incident luminance is calculated, and the aperture driving motor MA is driven in accordance with the calculated exposure amount (step 706). Next, an automatic focusing (AF) mode is performed according to the set shooting information to set the current position of the focus lens (step 707).

Next, it is checked whether the S1 signal, which is the first-stage signal from the shutter button 13, is on (step 708). If the S1 signal is not On, it ends because there is no user intention. If the S1 signal is On, the following steps are continued.

First, it is checked whether the S2 signal is on (step 709). If the S2 signal is not turned on, the user does not press the second stage of the shutter button 13 for capturing. Therefore, the process moves to the step 706.

If the S2 signal is On, the user presses the second stage of the shutter button 13 for shooting, and thus the shooting operation is performed (step 710). That is, the photoelectric converter OEC and the analog-to-digital converter 501 operate by the digital signal processor 507 controlling the operation of the timing circuit 502. Next, the image data is compressed (step 711) to generate a compressed image file (step 712). The generated image file is then stored in the user's memory card from the digital signal processor 507 via the memory card interface 506 (step 713).

It is preferable to have a step (step 833) of changing the camera operation mode to the next mode when the button is pressed.

At this time, it is preferable to sequentially change to another operation mode each time the play mode button is pressed. That is, when the operation mode is set to the display device power mode, the current camera operation mode is stored when the display device mode is set to the first mode by the operation of the color LCD panel (35 in FIG. 2), Next, when the display device mode is changed from the first mode to another mode by the operation of the color LCD panel 35, the photographing is performed by the camera operation mode previously stored. At this time, when the play mode button 30 is pressed again, the camera operation mode is switched to another mode, and when the play mode button 30 is pressed again, the camera operation mode can be sequentially switched to another mode.

In addition, when the operation mode is one of a still image shooting mode and a moving image shooting mode, and the display device mode is the first mode, it is preferable that the power mode is a power saving mode.
