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 zoom / split / volume button 39 included in the user input unit INP in the live-view mode or the video recording mode, 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.

For example, when a wide angle-zoom signal is generated, the focal length of the zoom lens is shortened to widen the angle of view, and when a telephoto-zoom signal is generated, the focal length of the zoom lens is increased. The angle of view becomes narrower. 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 focusing mode, the focus motor M _F is driven by the main controller embedded in the digital camera processor 507 controlling the driving unit 510 through the microcontroller 512. Accordingly, the focus lens is moved, and in this process, the position of the focus lens, that is, the focus position at which the luminance differences between adjacent pixels are the largest on average, is set as the driving step number of the focus motor M _F.

The compensating lens of the lens unit of the optical system OPS is not driven separately because it serves to compensate the overall refractive index. Reference numeral M _A denotes a motor for driving an iris (not shown).

In the filter portion of the optical system OPS, an optical low pass filter removes optical noise having a high frequency content. 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 camera 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, 501) as an analog-to-digital converter processes analog signals from the photoelectric converter (OEC), removes the high frequency noise, and adjusts the amplitude. To generate digital image data.

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

In the DRAM (Dynamic Random Access Memory) 504, digital image data from the digital camera processor 507 is temporarily stored. The EEPROM (Electrically Erasable and Programmable Read Only Memory) 505 stores algorithms necessary for the operation of the digital camera processor 507. In the memory card interface (MCI) 506, a user's memory card is detached.

The flash memory FM stores setting data or sticker image data necessary for the operation of the digital camera processor 507. Techniques associated with a sticker are described in detail in FIGS. 4 to 11.

When operating power is applied to the digital camera 1, the digital camera processor 507 executes initialization (step S401).

When this initialization step S401 is performed, the digital camera processor 507 performs a live-view mode (step S403). In this live-view mode, the input image is displayed on the display panel 35.

Next, when a sticker composition signal is generated from the user (step S405), the digital camera processor 507 performs a sticker selection mode (step S407). When this sticker selection mode (step S407) is performed, the sticker image selected by the user is synthesized and displayed on the live-view image. Accordingly, the user has the convenience of giving the sticker function to the image to be photographed. For example, if there is a person image of the user in the sticker menu, the user may generate a composite image of the user's person and a nice background by using a self photographing function. The detailed algorithm of the sticker selection mode (step S407) will be described with reference to Figs.

Next, if the SH1 signal, which is the first-stage signal from the shutter release button 13, is On (step S409), the digital camera processor 507 performs a shooting mode (step S411). The detailed algorithm of this shooting mode (step S411) will be described with reference to FIG.

Next, when signals corresponding to the setting mode are input among the input signals from the user input unit INP (step S413), a setting mode for setting operating conditions according to the input signals from the user input unit INP is performed. (Step S415).

On the other hand, if no end signal is generated (step S417), the digital camera processor 507 determines whether a conversion signal to any other mode has been generated (step S419).

If no conversion signal to any other mode has been generated in step S419, the digital camera processor 507 repeats step S403 and subsequent steps. If a conversion signal to any other mode, for example, a playback mode, is generated in step S419, the digital camera processor 507 repeatedly performs the step S403 and subsequent steps after performing the mode (step S420). do.

5 shows a detailed algorithm of step S407 of the sticker selection mode of FIG. 4. FIG. 6 shows an example of a live-view image of FIG. 4. FIG. 7 shows an example of an image 701 of a sticker file selected by a user in step S503 of FIG. 5. 8 is a step of 5 stickers in S509 - shows an example of the view image-target image (701 _B) is a live-view of synthesis of the resulting composite on a live image. Reference numeral 35 in FIGS. 6 and 8 indicates the color LCD panel of FIG. 3. In FIG. 7, reference numeral 701 _A denotes a sticker-background image.

3 and 5 to 8, the detailed algorithm of the step (S407) of the sticker selection mode of Figure 4 will be described as follows.

First, the digital camera processor 507 displays index images (also called thumbnail images) of sticker files stored in the flash memory 62 on the color LCD panel 35 (step S501).

When following this one index picture of stickers selecting by a user's operation (step S503), the selected from the index image sticker of the lower tone than the highest gray level - the target image (701 _B), a live-view image (the image of Fig. 6) Are synthesized and displayed (step S505).

The reason why the image of the gradations lower than the highest gradation becomes the sticker-target image 701 _B in step S505 is because the gradation of the sticker-background image 701 _A of the sticker image 701 is modulated to the highest gradation. . In step S505, the initial display position of the sticker-target image 701 _B is the center of the color LCD panel 35.

Next, when the direction signal generated by the user's operation (step S507), the digital camera processor 507 is sticky, depending on the direction signal, the view image color LCD panel (Synthesis live while moving the target image (701 _B) 35) (step S509). Therefore, the user sticky - can take place in the desired position the target image (701 _B).

9 shows a detailed algorithm of performing the shooting mode of FIG. 5 (step S411). The performance of this algorithm starts when the SH1 signal, which is the first stage signal from the shutter release button, is on. Here, the current position of the zoom lens is already set. A detailed algorithm of performing the shooting mode of FIG. 5 (step S411) will be described with reference to FIGS. 3 and 9 as follows.

First, the digital camera processor 507 checks the remaining amount of the memory card (step S4101) to confirm whether or not it is a capacity capable of recording pixel data (step S4103). If it is not a recordable capacity, the digital camera processor 507 indicates that the capacity of the memory card is insufficient, and then ends the shooting mode (step S411). In the case of a recordable capacity, the following steps are performed.

First, the digital camera processor 507 sets white parameters related to white balance by performing white balance setting according to shooting conditions currently set (step S4107).

Next, the digital camera processor 507 sets the appropriate exposure amount according to the average gradation of the input image (step S4109). Here, the aperture is driven in accordance with the set aperture value AV.

Next, the digital camera processor 507 performs auto focusing (step S4111).

Next, the digital camera processor 507 continues the following steps if the SH1 signal, which is the first stage signal from the shutter release button 13 in FIG. 1, is on (step S4113).

First, the digital camera processor 507 determines whether the SH2 signal, which is a two-stage signal from the shutter release button 13 in FIG. 1, is on (step S4115).

If the SH2 signal is not on, the digital camera processor 507 repeats the steps S4113 and S4115. Here, if the SH1 signal is not On, there is no user's intention of shooting, so the shooting mode (step S4) ends.

If the SH2 signal was On in step S4115, the digital camera processor 507 generates an image file in a memory card as a recording medium (step S4117). The digital camera processor 507 then performs image capture (step S4119). That is, the digital camera processor 507 receives the image data from the CDS-ADC element 501. Next, the digital camera processor 507 compresses the received image data (step S4121). The digital camera processor 507 stores the compressed image data in an image file (step S4123).

Next, the digital camera processor 507 displays the sticker-addition guidance message (step S4125). Accordingly, when the user decides to add the captured image to the sticker menu (step S4127), the digital camera processor 507 performs the sticker adding mode (step S4127). When this sticker adding mode (step S4127) is performed, the captured image is included in the sticker menu. Accordingly, the user can capture a desired image and use it as a sticker, and use more various sticker images.

FIG. 10 shows a detailed algorithm of step S4129 of the sticker adding mode of FIG. 9. 3, 6 to 8, and 10, the detailed algorithm of the step S4129 of the sticker addition mode of Figure 9 will be described as follows.

First, the digital camera processor 507 detects the contour from the captured image (eg, 701) to find the position of the sticker-target image 701 _B (step S1001).

Next, the digital camera processor 507 modulates all of the pixel gray levels of the area other than the sticker-target image 701 _B , that is, the area of the sticker-background image 701 _A , to the highest gray level, for example, the 256th gray level. (Step S1003).

Next, the digital camera processor 507 generates a sticker file in the sticker menu area of the flash memory 62 (step S1005).

Then, the digital camera processor 507 stores the modulated captured image data in a sticker file (step S1007).

FIG. 11 shows an algorithm of a playback mode in step S420 of performing the corresponding mode of FIG. 4. 3, 6 to 8, and 11, the algorithm of the playback mode in the step (S420) of performing the mode of Figure 4 will be described as follows.

First, the digital camera processor 507 plays back the image file that was most recently stored in the memory card (step S1101).

Next, when the direction signal is generated by the user's operation (step S1103), the digital camera processor 507 reproduces the next video file according to the direction signal (step S1105).

Next, when a sticker composition signal is generated by the user's operation (step S1107), the digital camera processor 507 performs the following steps.

First, the digital camera processor 507 displays index images (also called thumbnail images) of sticker files stored in the flash memory 62 on the color LCD panel 35 (step S1109).

Next, if a certain index image of a sticky selection by a user's operation (step S1111), stickers of the lower tone than the highest gray level in the selected index image - for playing a target image (701 _B) image (for example, in Fig. 6 The image is synthesized and displayed (step S1113).

As described above, the reason why the image of the gradations lower than the highest gradation becomes the sticker-target image 701 _B in step S1113 is that the gradation of the sticker-background image 701 _A is the highest gradation among the sticker images 701. This is because it is modulated. Sticky at the step S1113 - initial display position of the target image (701 _B) is the center of the color LCD panel 35.

Next, when the direction signal is generated by the user's operation (step S1115), the digital camera processor 507 moves the reproduced image to the color LCD panel 35 while moving the sticker-target image 701 _B in accordance with the direction signal. Display (step S1117).

Next, when a storage signal is generated by the user's operation (step S1119), the digital camera processor 507 generates an image file on the user's memory card, and then the sticker-composite image (e.g., the image of FIG. 8). ) Is stored in the video file (step S1121). Of course, the synthesized image data may be stored after being compressed in step S1121.

The above step S1103 and subsequent steps are repeatedly performed until the end signal is generated (step S1123).

As described above, according to the control method of the digital image processing apparatus and the digital image processing apparatus employing the method, the image captured in the shooting mode is included in the sticker menu according to the user's decision. Accordingly, the user can capture a desired image and use it as a sticker, and use more various sticker images.

Furthermore, since the sticker image selected by the user is synthesized and displayed on the live-view image, the user has the convenience of giving the sticker function to the image to be photographed.
