Description

Method of magnifying the image in digital image processing device}

The present invention relates to a digital image signal processing apparatus. More particularly, the present invention relates to an image enlarged display function in a digital image signal processing apparatus.

The user must move to the playback mode and use the zoom function in order to view a specific portion of the captured image in more detail as soon as the shooting is completed. Therefore, in order to find a part that the user wants to see in the already photographed image, there is a problem of returning to the menu again to play the desired image, and having to go through the trouble of finding and expanding a specific part every time.

In addition, conventionally, there is a technique of expanding the center of the AF in the captured image, but this also does not solve the above hassle because it enlarges the position of AF, not the portion desired by the user.

The user presets a part to be enlarged and viewed at the time of photographing so as to present a method of viewing the entire image and the image to be enlarged together at the moment of photographing completion.

The present invention solves the conventional problem through the image enlarged display method in the digital image signal processing apparatus. In the digital image signal processing apparatus, an image enlarged display method may include: setting a specific portion to be enlarged from a captured image portion captured by a frame in a preview screen shown on a display; And after capturing the captured image part, displaying a general Quick View window showing an entire image of the captured image and an enlarged Quick View window showing an enlarged image of the specific portion. It includes.

In the digital image signal processing apparatus of the present invention, the user may enlarge and view a portion of interest in the captured image simultaneously with the entire captured image. In this way, the user may not only enlarge and view an image of a specific person, but also easily detect noise in the case of a landscape photograph.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. The following description and the annexed drawings are for understanding the operation according to the present invention, a part that can be easily implemented by those skilled in the art can be omitted.

The operation unit 120 is a place that can input a control signal from the outside such as a user. The operation unit 120 exposes the image pickup device 115 to light for a predetermined time and releases a shutter-release button for inputting a shutter-release signal for taking a picture, a power button for supplying power, and an angle of view according to the input. There are a wide-angle zoom button and a tele-zoom button to widen or narrow the angle of view, and various function buttons such as selecting a text input or shooting mode, a playback mode, selecting a white balance setting function, and selecting an exposure setting function. The operation unit 120 may have various types of buttons as described above, but is not limited thereto, and may be implemented in any form that a user can input, such as a keyboard, a touch pad, a touch screen, a remote controller, and the like.

In addition, the digital photographing apparatus 100 may include a program storage unit 130 for storing a program such as an operating system or an application system for driving the digital camera, and a buffer storage unit for temporarily storing data or result data necessary for performing an operation. 140, a data storage unit 150 storing various information required for the program, including an image file including an image signal.

In addition, the digital photographing apparatus 100 includes a touch screen display 160 to display an operation state thereof or image information photographed by the digital photographing apparatus 100. The touch screen display 160 may provide visual and / or audio information to the user. At the same time, the touch screen display 160 is provided to receive an input through a user's touch. Accordingly, the touch screen display 160 operates as a user input interface with the operation unit 120.

In addition, the digital photographing apparatus 100 includes a digital signal processor 170 for processing an input image signal and controlling each component according to the input signal.

2 is a flowchart illustrating an image enlargement display function as a preferred embodiment of the present invention.

The digital image signal processing apparatus starts photographing the image (S210). In this case, the user may set whether to use an image enlargement display function or an image enlargement display menu that enlarges a portion of the captured image to be viewed. However, it should be noted that this setting may be set in advance by the user.

On the Preview screen of the digital image signal processing device, a display (see FIG. 3 (b) 320) for moving the direction is displayed. The user moves the display capable of moving the direction by using a button, a key, a direction key, etc. to the position where the user wants to enlarge and view the captured image (S220). The portion that the user wants to enlarge and view in the captured image may be a face portion of a specific person, a specific position in a landscape image, and the like.

The user photographs an image using a shutter key or a photographing button (S230).

When the shooting is completed, the digital video signal processing unit displays the normal Quick View showing the entire image of the user's captured image on the Double Quick View screen and the enlarged Quick View showing the enlarged image of the specific part of the image that the user wants to see. Display together (S240).

In this case, the magnified Quick View is shown together in a small pop-up window on top of the normal Quick View. You can use the Picture in Picture (PIP) algorithm to create a Double Quick View screen. Using the PIP algorithm, you can show the normal Quick View and Zoom Quick View in double layers on the display, and also resize the Normal Quick View and Zoom Quick View. However, it should be noted that the PIP algorithm proposed in the present invention is only one example of implementing the above. After that, the shooting is finished (S250).

For example, when the user takes a picture at a party or a year-end meeting, the user may set a location where a specific person is caught on the preview screen by using the image enlargement display function. When the user takes a picture, the Double Quick View screen shows a picture of all the people together and an enlarged picture of the part of the person.

As another example, an image of a portion enlarged in a pop-up window format on the Double Quick View screen is displayed on the display until the next picture is taken, thereby providing a function that can be compared with the previous picture.

According to another preferred embodiment, the noise may be checked using an image of an enlarged portion of the image on the Double Quick View screen. This is referred to FIG. 3.
