3 is a view showing the overall configuration including a control device of the digital camera of FIG. 1 and 2, 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.

Real time clock 503 provides time information to 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 21a or an RS232C interface 508 and its connection 21b, and a video filter ( 509 and video output 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.

4 is a flowchart illustrating a photographing algorithm performed by the digital camera of FIGS. 1 to 3.

Referring to the drawing, the shutter button 13 included in the user input unit INP has a two-stage structure. That is, after the user operates the wide-zoom button 39 _W and the tele-zoom button 39 _T , the S1 signal from the shutter button 13 is turned on by pressing the shutter button 13 only one step. When pressed to the second stage, the S2 signal from the shutter button 13 is turned on. Therefore, the photographing algorithm starts when the user presses the shutter button 13 one step (step 101). Here, the current position of the zoom lens is already set.

First, the shooting information is read out for setting the shooting conditions (step 101a). Next, the remaining amount of memory card is checked (step 102), and it is checked whether or not it is a capacity capable of recording a digital video signal (step 103). If it is not a recordable capacity, it is indicated that the capacity of the memory card is insufficient (step 104). In the case of a recordable capacity, the following steps are performed.

First, an automatic white balance (AWB) mode is performed in accordance with the shooting information read out in the shooting information reading step 101a to set relevant parameters (step 105).

Next, an automatic exposure (AE) mode is performed according to the shooting information read out in the shooting information reading step 101a, so that the exposure amount for the incident luminance is calculated, and the aperture driving motor M _A in accordance with the calculated exposure amount. ) Is driven (step 106).

Next, an automatic focusing (AF) mode is performed according to the shooting information read out in the shooting information reading step 101a to set the current position of the focus lens (step 107).

Next, it is checked whether the S1 signal, which is the first-stage signal from the shutter button 13, is on (step 108). 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 109). 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 106.

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 110). 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 111) to generate a compressed image file (step 112). 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 113).
