Accordingly, as the micro controller 512 controls the lens driving unit 510, the zoom motor M _Z is driven to move the zoom lens.

Meanwhile, in the automatic focusing mode, the main controller built in the digital camera processor 507 controls the driving unit 510 through the micro controller 512 to drive the focus motor M _F. Thus, the focus lens is moved. In this process, the number of drive steps of the focus motor M _F , for example, the position of the focus lens where the high frequency component of the image signal is the largest, is set. Reference symbol M _A denotes a motor for driving an aperture (not shown).

The main photoelectric conversion unit OEC of the charge coupled device (CCD) converts light from the main optical system OPS into an electrical analog image signal. Here, the digital camera processor 507 controls the timing circuit 502 to control the operations of the main photoelectric converter OEC and the main analog-to-digital converter 501. The main CDS-ADC (Correlation Double Sampler and Analog-to-Digital Converter) element 501 as the main analog-to-digital converter unit processes the analog video signal from the main photoelectric converter (OEC) to remove the high frequency noise. After adjusting the amplitude, it is converted into digital image data.

If no conversion signal to another mode is generated in step S8, the digital camera processor 507 repeats step S2 and the following steps. If a conversion signal to another arbitrary mode is generated in step S8, the digital camera processor 507 repeats the step S2 and the subsequent steps after performing the corresponding mode (step S9).

(Preview) Reference contour information of the user's face is obtained from the image data (step S52). In other words, reference contour information of the user's face is obtained from the preview image data from the auxiliary CDS-ADC element 47. Here, the well-known contour recognition algorithm is used. In summary, whether to contour is determined according to the gray level difference between adjacent pixels.

Next, the digital camera processor 507 determines whether the current contour information temporarily stored in the DRAM 504 is equal to the reference contour information (see FIG. 5) (step S605).

If the current outline information is not the same as the reference outline information in step S605, the digital camera processor 507 displays the message "The user cannot be photographed because it is different" on the color LCD panel (step S607).

If the current outline information is not the same as the reference outline information in step S605, the digital camera processor 507 continues the following steps.

The digital camera processor 507 determines whether the SH2 signal, which is the two-stage signal from the shutter release button 13 in FIG. 1, is on (step S609).

If the SH2 signal is not On in step S609, the digital camera processor 507 determines whether the SH1 signal, which is the first stage signal from the shutter release button 13, is in the On state (step S611). .

If the SH1 signal, which is the first-stage signal from the shutter release button 13, is in the on state in step S611, since the user intends to capture, the step S609 is performed again. If the SH1 signal, which is the first-stage signal from the shutter release button 13 in the step S611, is in the off state, the intention of photographing by the user has disappeared, so that the digital camera processor 507 terminates the execution of this algorithm.

If the SH2 signal is On in step S609, since the user has pressed the shutter release button 13 completely, the digital camera processor 507 continues the following steps.

The digital camera processor 507 generates an image file in the memory card (step S613).

Next, the digital camera processor 507 temporarily stores the obtained current contour information in the DRAM 504 (step S73).

Next, the digital camera processor 507 judges whether or not the current contour information temporarily stored in the DRAM 504 is the same as the reference contour information (see FIG. 5) (step S75).

If the current outline information is the same as the reference outline information in step S605, the digital camera processor 507 performs focusing (step S77).

Steps S71, S73, S75, and S77 are repeated periodically.

Next, the digital camera processor 507 determines whether or not the current contour information temporarily stored in the DRAM 504 is the same as the reference contour information (see FIG. 5) (step S85).

Next, in step S85, if the current outline information is equal to the reference outline information, the color LCD panel 35 is turned on (step S87).

If the current outline information is not the same as the reference outline information in step S85, the color LCD panel 35 is turned off (step S89).

Steps S81, S83, S85, S87, and S89 are repeatedly performed periodically.

According to the algorithm of FIG. 8 as described above, if the current contour information from the preview image data of the user-face detection unit 48 is periodically compared with the reference contour information, and if the current contour information is equal to the reference contour information, the color LCD panel If 35 is on and the current contour information is not equal to the reference contour information, the color LCD panel 35 is off.
