BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a digital image processing apparatus having an image capturing function, such as a digital camera, and more particularly to a digital image processing apparatus having a segment capturing function.

The split shooting function is a digital camera function that obtains a single image by splitting and synthesizing multiple shots.

1A to 1C illustrate a conventional split photographing process, which illustrates a process of two-split shooting, three-split shooting, four-split shooting, and a split-shot image configuration.

In the conventional divided photographing function, photographing is sequentially performed as many times as the number of divisions selected by the user, and automatic saving is performed immediately. Referring to FIG. 1C illustrating a process of four-part shooting, divided shooting is performed in the order of shooting 1 → shooting 2 → shooting 3 → shooting 4 → autosave.

The conventional segmented photographing function is automatically stored even when an image is incorrectly photographed or an unfavorable image is photographed due to a user's mistake or poor focusing or a bad auto-white balance (AWB). For this reason, there is a problem that if a single mistake occurs in a plurality of shots, the entire split shot image is ruined.

In addition, the divisional shooting function of the conventional digital camera can be stored only when all the shooting is completed. For this reason, when a photographing mistake occurs in the middle, there is a problem in that rephotography is performed from the beginning.

In addition, since the conventional digital camera's split shooting function does not allow re-shooting when the captured image is reproduced, there is a problem in that only a part of the split-photographed image cannot be modified after shooting and storing the image.

Here, the DSP 7 controls the timing circuit 2 to control the operations of the photoelectric converter OEC and the analog-digital converter 1. The CDS-ADC (Correlation Double Sampler and Analog-to-Digital Converter) element 1 as an analog-to-digital converter processes the analog signal from the photoelectric converter (OEC), removes the high frequency noise, and adjusts the amplitude. (auto gain control, AGC) and then convert to a digital signal. The DSP 7 processes the digital signal from the CDS-ADC element 1 to generate a digital image signal classified into luminance and chroma signals.

The DRAM (Dynamic Random Access Memory) 4 temporarily stores digital image signals and other temporary processing data from the DSP 7.

The EEPROM (Electrically Erasable Programmable Read Only Memory) 5 stores algorithms and setting data necessary for the operation of the DSP 7. The memory card of the user is attached to and detached from the memory card interface 6.

The digital image signal from the DSP (Digital Signal Processor) 7 is converted into the display signal of the LCD panel by the LCD driver 14 so that the image is displayed on the color LCD panel 17.

On the other hand, the digital image signal from the DSP 7 can be transmitted by serial communication via the USB (Universal Serial Bus) connection 18 or the RS232C interface 8 and its connection 19, and the video filter 9 And a video signal through the video output unit 20.

The audio processor 13 outputs the audio signal from the microphone MIC to the DSP 7 or the speaker SP, and outputs the audio signal from the DSP 7 to the speaker SP.

The user input unit INP may include a shutter button, a mode selection button, a function selection button, a zoom button, a direction movement button, and the like. The user input unit INP is operated by the user to generate a command for performing each function according to the user's instruction.

It will be appreciated that the functionality of the various components may be implemented in combination.

3 is a diagram illustrating an example of a rear surface of a digital camera as shown in FIG. 2 as an example of a digital image processing apparatus to which the present invention may be applied.

At the rear of the digital camera of Fig. 3, the viewfinder 100, autofocus lamp 101, flash status lamp 102, mode dial 103, wide-angle zoom button 104, telephoto zoom button 105, 5 Function button 106, speaker 107, external output terminal 108, DC power input terminal 109, playback mode button 110, LCD monitor 111, display the currently set shooting information on the monitor or LCD monitor An LCD button 112, a manual focus button 113, a pause button 114 and the like are provided to turn off / turn on.

In this case, the five-function button 106 includes a menu entry / confirmation button and a top, bottom, left and right direction buttons at the center. When the menu is displayed on the monitor, the up, down, left, and right directional buttons can function as special function buttons instead of directional movement.

The various function buttons shown in FIG. 3 may be provided to perform two or more complex functions in addition to the functions shown in the names. For example, the manual focus button 113 may act as a delete button in a specific mode, for example, the division shooting mode, the reproduction mode, or the like of the present invention.

In the present invention, which will be described in detail below, the image of the division photographing mode includes an optical system (OPS) including the lens unit and the filter unit of FIG. It is taken through. Also, the captured divided image is temporarily stored in the DRAM 4 from the DSP 7 of FIG. 2 or read out. The digital image signal from the DSP 7 is converted into the display signal of the LCD panel by the LCD driver 14 so that the image is displayed on the color LCD panel 17. The DSP 7 of FIG. 2 can read the divided image temporarily stored in the DRAM 4 and store it in a recording medium such as the memory card 6 in order to perform the divisional imaging method of the present invention.

FIG. 4 is a flowchart for describing a method of divisional photographing of a digital image processing apparatus according to an exemplary embodiment of the present invention.

First, it is continuously determined whether the division shooting mode is selected (S100). The split shooting mode is a function for displaying a plurality of images simultaneously on one screen when shooting still images. When selecting the split shooting mode, the number of split screens, for example, two divisions, three divisions, and four divisions, can be selected.

When the split shooting mode is selected, images are sequentially taken by the user's shutter button input, and the split images are extracted and temporarily stored in the allocated split screen position (S102).

In step S102, it is determined whether to re-take the image stored immediately before (S104). Whether or not to retake the image may be determined as the occurrence of an interrupt caused by the input of a delete button provided in the user input unit (INP in FIG. 2).

If it is determined that the delete button is inputted to retake the image, the previous temporarily stored image is deleted and the flow returns to step S102 (S106).

If the segmentation shooting is not completed, the process proceeds to step S102 again (S108). For example, whether split shooting is completed is determined as the occurrence of an interrupt by inputting a predetermined confirmation button (106 in FIG. 3) provided in the user input unit (INP in FIG. 2) by the user's operation as the last captured image. Can be.

If the user continuously inputs the shutter button without inputting the delete button during the segmented image capturing, the segmented image capturing is continuously performed without generating the interruption of the re-photographing instruction in step S104 and the segmentation photographing completion instruction in step S106.

When the split shooting is completed, the divided shot image is temporarily stored in the recording medium (S110). In step S110, the divided photographing information of each divided image, for example, the number of divided images, the divided size, and the number of divided images may be stored together. This is to make it possible to re-capture some of the divided images at the time of reproducing the image shot and stored.

The divided images photographed in each of the above-described steps are displayed on the display panel (17 in FIG. 2 and 111 in FIG. 3) via the display driver (14 in FIG. 2).

FIG. 5 illustrates an example in which the divided photographing process of the digital camera of FIG. 4 is displayed on a display panel according to a user's operation order.

First, in step S100, the user selects a special effect mode from the menu, selects split shooting as a submenu, and selects 4 divisions as the number of split screens.

And in step S102, the user sequentially inputs the shutter button without inputting the delete button on the way, and continuously photographs images from No. 1 to No. 2 to No. 3.

Then enter the delete button. If the delete button is input, an interrupt occurs and it is determined that the previous temporarily stored image 3 is taken in step S104. In the present embodiment, the delete button is illustrated as the re-shooting instruction generating means, but the present invention is not limited thereto, and other buttons may be used.

If the user moves the cursor to enter cancel, reshooting is canceled.

If the user inputs a confirmation button, the last image temporarily stored in step S106 is deleted.

When the user inputs the shutter button, image 3 is retaken and temporarily stored in step S102.

If the user inputs the shutter button again, image 4 is taken and temporarily stored in step S102.

Although not shown in the drawing, when the user finally inputs the segmentation photographing completion, the segmentation photographing is completed, and the 4-split image is stored in the recording medium. When storing an image, the image may be compressed and stored by a predetermined compression format such as a JPEG (joint photographic coding experts group) file format.

FIG. 6 is a flowchart for describing a method of divisional photographing of a digital image processing apparatus according to another exemplary embodiment of the present invention.

First, it is continuously determined whether the division shooting mode is selected (S200). The split shooting mode is a function for displaying a plurality of images simultaneously on one screen when shooting still images. When selecting the split shooting mode, the number of split screens, for example, two divisions, three divisions, and four divisions, can be selected.

When the split shooting mode is selected, all images are taken as many times as the number of divisions sequentially set by the user's shutter button input, and the divided images are extracted and temporarily stored in the allocated split screen position (S202).

In operation S202, it is determined whether one or more of the temporarily stored divided images are to be re-photographed (S204). Whether or not to retake the image may be determined as the occurrence of an interrupt caused by the input of a delete button provided in the user input unit (INP in FIG. 2).

If it is determined that the delete button is input and retakes, the image to be retaken is selected and deleted (S206).

In order to replace the deleted segmented image, the photographed image is temporarily stored and the process proceeds to step S204 (S208).

In step S208 it is determined whether to retake. If the user instructs to retake again, the above-described steps S206 and S208 are performed. In step S208, if the user inputs the completion of reshooting, the reshooting is completed, and the divided shot image is temporarily stored in the recording medium (S210). In step S210, the divided photographing information (division, division size) of each divided image may be stored together. This is to make it possible to re-capture some of the divided images at the time of reproducing the image shot and stored.

FIG. 7 illustrates an example in which the divided photographing process of the digital camera of FIG. 6 is displayed on a display panel according to a user's operation order.

First, in step S200, the user selects a special effect mode from the menu, selects split shooting as a submenu, and selects 4 divisions as the number of split screens.

In step S202, the user sequentially inputs the shutter button without inputting the delete button in the middle, and continuously photographs the images from the first image to the second image.

Then enter the delete button. When the delete button is input, it is determined that a re-shooting instruction interrupt occurs to re-take the temporarily stored split image (S204).

If the user moves the cursor to enter cancel, reshooting is canceled.

If the user inputs a direction button to select the re-captured split image, for example, image 3 and inputs a confirmation button, image 3 is deleted.

When the user inputs the shutter button, image 3 is retaken and temporarily stored in step S208.

Although not shown in the drawing, when the user finally inputs the segmentation photographing completion, the segmentation photographing is completed, and the 4-split image is stored in the recording medium. Of course, if the user inputs the delete button again to generate a re-shooting instruction interrupt, the steps S204, S206, and S208 are repeated.

FIG. 8 is a flowchart for describing a method of performing segmented photographing of a digital image processing apparatus according to still another preferred embodiment of the present invention.

First, the divisional shot image is selected and played in the playback mode (S300).

The reproduced divided image stores information of the divided image, for example, each divided image, the number of divided images, and the divided size.

In operation S302, it is determined whether to re-photograph the reproduced divided image. Whether or not to retake the image may be determined as the occurrence of an interrupt caused by the input of a delete button provided in the user input unit (INP in FIG. 2).

When it is determined that the divided shot image is to be retaken, the divided shot image is decompressed and the divided images are temporarily stored (S304).

When the re-shooting target image is selected by the user's operation, the re-selected split image is deleted (S306).

In order to replace the deleted segmented image, it is retaken and temporarily stored (S308).

In step S310 it is determined whether the reshooting is complete. If the user instructs to retake again, the above-described steps S306 and S308 are performed. For example, whether or not reshooting is completed may be determined as an interrupt occurrence by input of a predetermined confirmation button provided in the user input unit (INP in FIG. 2) by a user's operation.

If the user inputs the reshooting completion in step S310, the reshooting is completed, and the divided shot image is temporarily stored in the recording medium (S312). In step S312, the divided photographing information (division, division size) of each divided image may be stored together. This is to make it possible to re-capture some of the divided images at the time of reproducing the image shot and stored.

FIG. 9 illustrates an example in which the divided photographing process of the digital camera of FIG. 8 is displayed on a display panel according to a user's manipulation order.

First, in step S300, the user selects and reproduces the image which has been divided and stored in the playback mode.

When the user inputs the delete button in step S302, an interrupt occurs to enter the reshooting mode.

When entering the re-shooting mode, by using the information on the number of divisions and the size of the divided image is temporarily stored so that each of the divided images can be retaken.

If the user moves the cursor to enter cancel, reshooting is canceled.

In step S306, if the user inputs the direction button to select the re-photographing target split image, for example, image 3 and inputs the confirmation button, image 3 is deleted.

When the user inputs the shutter button, image 3 is retaken and temporarily stored in step S308.

Although not shown in the drawing, when the user finally inputs the segmentation photographing completion, the segmentation photographing is completed, and the 4-split image is stored in the recording medium. Of course, if the user inputs the delete button again to generate a re-shooting instruction interrupt, steps S306 and S308 are repeated.
