Abstract
The present invention relates to an image enlarged display method in a digital image signal processing apparatus. In the image magnification method of the present invention, in the preview screen shown on the display, a step of setting a specific part to be enlarged and viewed from the captured image part captured by the frame, and a general Quick View window showing the entire image of the captured image and an enlarged image of the specific part Displaying the zoomed Quick View window together. In this way, the user has an advantage of being able to view a magnified image of a desired part immediately without taking a zoom function by entering a playback menu separately.
Description
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.
In addition, the specification and drawings are not provided to limit the invention, the scope of the invention should be defined by the claims. Terms used in the present specification should be interpreted as meanings and concepts corresponding to the technical spirit of the present invention so as to best express the present invention.
Embodiments of the present invention will now be described with reference to the accompanying drawings.

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.
3 (a) to 3 (c) show an example of implementing an image magnification function of the present invention.
As shown in (a) of FIG. 3, an image magnification display menu or an image magnification display function is selected before photographing on a preview screen of the digital image signal processing apparatus. Thereafter, a
As shown in (c) of FIG. 3, the user may detect noise through an image that he / she wants to enlarge.
3 (d) sequentially illustrates the processes of FIGS. 3 (a) to 3 (c).
4 (a) to 4 (c) show another example of implementing the image magnification function of the present invention.
A preview screen as shown in FIG. 4A is shown to the user. The user may designate to enlarge an image of a specific target among a plurality of shooting targets on the preview screen as shown in FIG. 4 (b). After the shooting, the entire image and the enlarged image of the desired portion can be viewed together as shown in FIG.
Meanwhile, the present invention may be implemented by storing computer readable codes in a computer readable storage medium. The computer readable storage medium includes all kinds of storage devices for storing data that can be read by a computer system.
When the computer readable code is read and executed by the digital
Examples of computer readable storage media include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, and the like, and also include implementing in the form of a carrier wave (eg, transmission over the Internet). The computer readable storage medium can also be distributed over network coupled computer systems so that the computer readable code is stored and executed in a distributed fashion.
The present invention has been described above with reference to preferred embodiments. Those skilled in the art will understand that the present invention can be implemented in a modified form without departing from the essential features of the present invention. Therefore, the above-described embodiments should be considered in an illustrative rather than a restrictive sense. The scope of the present invention is defined by the appended claims rather than by the foregoing description, and the inventions claimed by the claims and the inventions equivalent to the claimed invention are to be construed as being included in the present invention.
