A photographing apparatus for saving and a part screen editing method thereof.

The photographing apparatus refers to a device for recording and reproducing an image signal generated by capturing a subject, and an audio signal on a recording medium through predetermined signal processing. The photographing apparatus can use a magnetic tape as a recording medium, and can record a video for a long time. In general, examples of the recording apparatus include a camcorder capable of capturing video, that is, a digital video camera (DVC), and a digital still camera (DSC) capable of capturing DVC and still images. And a composite photographing apparatus in which a single case is integrated.

Such a photographing apparatus provides a special effects mode for special processing such as beautifying or changing an image displayed on a screen. A typical special effect provided by the video recording / reproducing apparatus is a mosaic effect.

However, the conventional photographing apparatus applies a special effect to the entire image displayed on one screen. In other words, the conventional photographing apparatus cannot process only the image of the partial screen desired by the user in the image displayed on the full screen.

Thus, for partial screen editing for partially applying special effects to an image displayed on the entire screen, an auxiliary device such as a PC having an editing program for providing partial screen editing has been required.

In addition, when recording a special effect processed image, the conventional photographing apparatus recorded the special effect processed image as it is on the recording medium.

Therefore, when the recorded medium is to be reproduced, it is impossible to recover the original image when the original image of the special effect processed image is not viewed.

Accordingly, an object of the present invention is to provide a photographing apparatus and a partial screen editing method capable of partial screen editing which partially processes an image displayed on the entire screen without the need for an editing program and an auxiliary device.

Another object of the present invention is to provide a photographing apparatus capable of editing a partial screen for preserving the original video recorded by the special effect processing, and a method for editing the partial screen.

Partial screen editing method of the photographing apparatus of the present invention for achieving the above object, the step of displaying the selected special effect region selected from the original image by processing the special effect and the original image and the partial special effect region information on the recording medium, respectively Storing.

The partial special effect region information is information about a region selected for processing a special effect among the original image, and includes (x-axis starting position, y-axis starting position) and (x-axis ending position, y-axis ending position) of the selected region. It is preferable to include).

In addition, it is preferable to output at least one of the original image and the image processed by the special effect on the image corresponding to the partial special effect area information according to whether the partial special effect is applied during playback.

More preferably, when the partial special effect is applied, an image obtained by combining the image corresponding to the partial special effect zero information with the special effect is output to the original image, and the original image is output when the partial special effect is not applied.

On the other hand, the photographing apparatus according to the present invention, the storage unit for storing the original image and the partial special effect area information and the partial special effect region selected from the original image by processing the special effects, and displays the original image and the DSP (Digital Signal) for storing partial special effect area information and outputting at least one of the original image and the image processed by the special effect on the image corresponding to the partial special effect area information depending on whether the partial special effect is applied during playback. Processor).

Hereinafter, with reference to the drawings will be described in detail the present invention.

1 is a block diagram of a camcorder according to an embodiment of the present invention.

The camcorder is an example of a photographing apparatus that processes a special effect on an image displayed on one screen among images input from the outside, that is, an image of a region selected for processing a special effect on one field of image. Similarly, the camcorder performs special effect processing on an image of a region selected for special effect processing on an image of one field reproduced on one screen among images recorded on a recording medium.

In addition, the camcorder records the original image and the "information about the region selected for special effect processing" (hereinafter, the "partial special effect region") during the recording after the special effect processing of the image of the region selected from the image of one field displayed on one screen. Information ".

When the recorded image is reproduced, the camcorder reproduces the original image or the image corresponding to the partial special effect area information according to the selection of the partial special effect application.

Referring to FIG. 1, a camcorder includes an imaging unit 110, a DSP 120, a display unit 130, a VCR unit 140, a memory 150, a key input unit 160, and a controller 170. .

The imaging unit 110 photoelectrically converts an optical signal incident through the lens into an electrical signal, and performs predetermined signal processing on the converted signal. The imaging unit 110 is capable of capturing both moving and still images, and includes a lens unit 112, a charge coupled device (CCD) 114, and a correlated double sampler / auto gain controller / analog-to-CDS / AGC / ADC. Digital converter 116 is provided.

The CCD 114 converts an optical image incident through the lens unit 112 into an electrical signal and outputs the electrical signal. That is, the optical image of the subject is formed on the optical surface of the CCD 114 by the lens unit 112, and the CCD 114 converts the optical image formed on the photosensitive surface into an electrical signal and scans horizontally and vertically. Output in the form of electrical signals in dimensions.

The CDS / AGC / ADC 116 uses CDS (Correlation Dual Sampler) to remove noise from the signal output from the CCD 114 and to keep the level of the signal constant using an AGC (automatic gain control element). The gain is adjusted and converted to a digital signal using an analog-to-digital converter.

The digital signal processor (DSP) 120 performs a predetermined signal processing on the image signal received from the imaging unit 110 and applies the signal processed image to the display unit 130 to be described later.

At this time, when the partial special effect mode is selected and the "region to apply the partial special effects in the image of one field" (hereinafter referred to as the "partial special effect region") is selected, the DSP 120 displays the image of the one field in the special mode. The effects are processed and stored in the memory 150 to be described later. The DSP 120 superimposes an image corresponding to the selected partial special effect region of the special effect processed image stored in the memory 150 on the original image of one field so as to be displayed.

The partial special effects mode is a mode for processing special images of the selected partial special effects area. The partial special effects include mosaic effect, art effect, sepia effect, black & white effect, and blur. Blur effect, mirror effect, and negative effect.

The DSP 120 compresses the original image and then applies the compressed original image and the partial special effect region information to the VCR unit 140, which will be described later, when the partial special effect image is recorded.

The partial special effect area information is information on an area selected for special effect processing, and includes (x-axis starting position, y-axis starting position) and (x-axis ending position, y-axis ending position) of the selected region.

On the other hand, when the camcorder operates in the playback mode, the DSP 120 receives the compressed image and the partial special effect area information from the VCR unit 140. The DSP 120 extends the applied compressed image and applies it to the display unit 130.

In this case, when the application of the partial special effects is selected, the DSP 120 processes the image corresponding to the received partial special effect area information by special effect and displays the processed special effects. The DSP 120 processes the partial special effects in the same manner as in the partial special effects mode.

In addition, when the camcorder operates in the playback mode, if the partial special effect mode and the partial special effect area are selected during playback, the DSP 120 applies the partial special effect mode.

The display unit 130 displays an image output from the DSP 120, and includes an on screen display (OSD) unit 132 and a liquid crystal display (LCD) 134.

The OSD unit 132 combines the menu screen for the partial special effect mode with the image output from the DSP 120. The OSD unit 132 generates (x-axis starting position, y-axis starting position) and (x-axis ending position, y-axis ending position) of the selected partial special effect region.

The LCD 134 is a display device that displays an image received from the DSP 120 and has a touch screen function. The user can select a menu for the partial special effect mode and the partial special effect area on the LCD 134 using the touch screen function.

The VCR unit 140 records the original image and the partial special effect area information output from the DSP 120 on the VCR tape 144, or reads the original image and the partial special effect area information recorded on the VCR tape 144. The VCR deck unit 142 is applied to the DSP 120.

The memory 150 stores a special effect processed image of one field to be partially processed.

The key input unit 160 includes a selection button for selecting a partial special effect mode, a special effect to be applied, and whether to apply the special effect during playback, and a direction key for selecting the partial special effect area.

The controller 170 controls the operation of the partial special effect processing mode according to a user's operation command input through the touch screen LCD 134 or the key input unit 160.

Referring to FIG. 2, the controller 170 determines whether a partial special effect mode is selected (S200). The user can select the partial special effect mode using the touch screen LCD 134 or the key input unit 160.

If it is determined that the partial special effects mode is selected, the DSP 120 processes the image of one field selected to process the partial special effects under the control of the controller 170 and stores the image in the memory 150 in a special effect (S210).

The DSP 120 determines whether a partial special effect region is selected (S220). The partial special effect area is selected by the LCD 134 or the key input unit 160 having a touch screen function in the image of one field selected to process the partial special effect.

When it is determined that the partial special effect region is selected, the DSP 120 superimposes an image corresponding to the selected partial special effect region among the special effect processed images stored in the memory 150 on the image of the one field selected to process the partial special effect. Let (S230).

The DSP 120 applies the partial special effect processed image to the LCD 134 so as to be displayed, and records the original image and the partial special effect area information not subjected to the partial special effect processing on the VCR tape 144 (S240).

The controller 170 determines whether to play back the video recorded on the VCR tape 144 (S250). When a playback command is input by the key input unit 160, the controller 170 controls to play back the image recorded on the VCR tape 144.

If it is determined that the recorded image is to be played back, the controller 170 determines whether to apply the partial special effect (S260). The OSD unit 132 combines and displays a message asking whether to apply a partial special effect to the image reproduced by the DSP 120 on the LCD 134. The user may select whether to apply the partial special effect by using the LCD 134 or the key input unit 160 having a touch screen function.

If it is determined that the partial special effect is to be applied (S260-Y), the DSP 120 processes the image corresponding to the partial special effect area information under the control of the controller 170 and displays the special effect on the LCD 134 ( S270). In this case, two heads may exist in the VCR deck unit 142 that reads the image and the partial special effect area information recorded on the VCR tape 144 and applies the DSP 120 to the DSP 120. When the partial special effect is applied, one head reads the image recorded on the VCR tape 144 and applies it to the DSP 120, and the other head reads the partial special effect area information recorded on the VCR tape 144 and then reads the DSP 120. Is applied.

If it is determined that the partial special effects are not to be applied (S260-N), the DSP 120 displays the original image on which the partial special effects have not been processed on the LCD 134 (S280).
