Although the image processing apparatus of
The image processing apparatus may select a plurality of images when the slideshow function is performed, and perform image processing on the selected images simultaneously after the slideshow function is performed.
The image processing apparatus may include the imaging unit 3 that captures an image. The imaging unit 3 includes an imaging device 20 that captures the image of a subject and converts the captured image into an electrical signal, an image converting unit 41 that converts the electrical signal transmitted by the imaging device 20 into image data, and an imaging controller 49 that controls operation of the imaging device 20. The image light of a subject is incident to the imaging device 20 through an optical system 10 disposed in front of the imaging device 20.
The optical system 10 disposed in front of the imaging device 20 includes a plurality of lenses 12, and forms an image on a surface of the imaging device 20 by using external image light. The lenses 12 are disposed such that intervals therebetween are changeable. By changing the intervals of the lenses 12, a zoom magnification and a focus of the optical system 10 may be controlled.
The lenses 12 are driven by a zoom driver 11 having a driving unit, such as a zoom motor, for changing the relative locations of the lenses 12. The lenses 12 may include a zoom lens for enlarging or reducing the size of the image of a subject, and a focus lens for controlling focusing of a subject. The zoom driver 11 is driven in correspondence to a control signal applied by a driving circuit unit 42 of a controller 40. Thus, the zoom driver 11 may drive the optical system 10 so that the optical system 10 has any one of a plurality of enlargement magnifications.
The imaging device 20 may include a photoelectric conversion device such as a charge-coupled device (CCD) or a complementary metal-oxide semiconductor (CMOS), and converts an image light that enters through the optical system 10 into an electrical signal. The imaging device 20 is driven in correspondence to a control signal applied by the imaging controller 49.
The image converting unit 41 performs image processing on the electrical signal of the imaging device 20 or converts the electrical signal into image data that may be stored in a storage medium.
The electrical signal transmitted by the imaging device 20 may be converted by the image converting unit 41 according to the following method. For example, the method may include: reducing driving noise of the electrical signal transmitted by the imaging device 20 by using a correlated double sampling (CDS) circuit; adjusting the gain of a signal obtained after noise is reduced, wherein the adjusting is performed by an automatic gain control (AGC) circuit; converting an analog signal into a digital signal by using an analog-to-digital (A/D) converter; and performing correcting for pixel defects with respect to a digital signal, gains correction, white balance correction, and gamma correction. The CDS circuit, the AGC circuit, and the A/D converter may be independent circuits.
The image converting unit 41 may convert the electrical signal of the imaging device 20 into RGB data and then convert the RGB data into raw data such as a YUV signal including a luminescence Y signal and a color difference UV signal.
The controller 40 is electrically connected to the imaging device 20, the zoom driver 11, a touch screen 50, the user input unit 60, and the storage unit 14. The controller 40 exchanges control signals with these elements in order to control operation of the elements, and processes data.

The controller 40 may be embodied as a microchip or a circuit board including a microchip, and constituents of the controller 40 may be embodied by software or circuits installed in the controller 40.
The storage controller 43 controls writing of data to the storage unit 14 and reading of the written data or set information. The storage unit 14 may include a volatile internal memory. The volatile internal memory may include a semiconductor memory device such as a synchronous dynamic random access memory (SDRAM). The storage unit 14 may perform a buffer memory function for temporarily storing raw data generated by the image processor 70, and an operation memory function that is used when the image processor 70 processes data.
The storage unit 14 may also include a non-volatile external memory. The non-volatile external memory may be, for example, a memory stick, a flash memory such as secure digital (SD)/multimedia card (MMC), a storage device such as a hard disk drive (HDD), or an optical storage device such as a DVD or CD. The storage unit 14 may store image data that is compressed in the form of a JPEG file or a TIFF file by the compression processor 48.
The image processing apparatus according to the present embodiment may include the touch screen 50 that includes a display unit 51 that displays an image of a file stored in the storage unit 14 and an input unit 52 that selects a portion of the image displayed by the display unit 51. The touch screen 50 may display an image captured by the imaging device 20 and generate a signal corresponding to a touched location by sensing the touch on a surface of the touch screen 50.
The touch screen 50 is an input device that may be used instead of a keyboard and a mouse. Since the touch screen 50 allows a user to directly touch the surface of a display with a finger or a pen in order to perform a desired operation, the user may perform desired operations under a graphical user interface (GUI) environment.
The display unit 51 of the touch screen 50 may be a display device such as a liquid crystal display (LCD) or an organic light-emitting display (OLED). The display unit 51 may display an image corresponding to image data stored in the storage unit 14.
The input unit 52 may be installed on a surface of the display unit 51 and senses a touch of the surface of the display unit 51. The input unit 52 may be an example of the user input unit 60 included in the image processing apparatus according to the present embodiment. The input unit 52 may include a resistance sensing unit, a capacitive sensing unit, a sensing unit using a surface acoustic wave, a sensing unit using infrared (IR) rays, or an optical sensing unit.
By contacting the input unit 52 of the touch screen 50, a user selects a menu in an image displayed by the display unit 51 and performs the due operation, or designates an identified region.
The image processing apparatus may include the user input unit 60 that is separately formed from the touch screen 50. The user input unit 60 may be embodied as, for example, menu buttons or a dial. A user may manipulate the user input unit 60 when reduced images are displayed by the display unit 51, in order to perform a slideshow function and select images. The user input unit 60 generates an input signal by recognizing manipulation of a user, and applies the generated input signal to the user interface 46.
The compression processor 48 may compress image data generated by the imaging unit 3 or extract the compressed image data. The image data may be compressed in the form of a JPEG file or a TIFF file. JPEG is an image compression standard set by the Joint Photographic Experts Group, and is a file format that is a widely used to compress a still image such as a picture owing to its high compression efficiency.
The slideshow performing unit 45 performs the slideshow function of sequentially displaying the images corresponding to the files stored in the storage unit 14 on the display unit 51 at a predetermined time interval. The slideshow performing unit 45 controls the storage controller 43 to sequentially read the files stored in the storage unit 14, decompresses the files read by controlling the compression processor 48, and controls the touch screen controller 44, thereby forming the images on the display unit 51.
The user input unit 60 may receive an input manipulation of the user when the slideshow function of sequentially displaying the images corresponding to the files stored in the storage unit 14 on the display unit 51 is performed. In more detail, the user may select images through the user input unit 60 or by manipulating the input unit 52 of the touch screen 50 when the slideshow function is performed.
The slideshow performing unit 45 may memorize the images selected by the user from among the images displayed according to the slideshow function based on an input signal of the user input unit 60. The slideshow performing unit 45 memorizes the selected images in order to perform image processing on the images selected by the user after the slideshow function is completed. The image processing apparatus according to the present embodiment includes the list creating unit 47 that creates a list of the files of the selected images in order to memorize the selected images in the slideshow performing unit 45.
