The imaging unit 33 includes a shutter, a lens unit, an aperture, a charge coupled device (CCD), and an ADC, which are not shown in the figure. The shutter is a mechanism for adjusting the amount of light exposed together with the aperture. The lens unit receives light from an external light source and processes an image. At this time, the iris adjusts the amount of light incident (light quantity) according to the degree of opening and closing. The opening and closing degree of the iris is controlled by the digital signal processing unit 39.

The CCD accumulates the amount of light input through the lens unit and outputs an image captured by the lens unit in accordance with the accumulated light amount in accordance with the vertical synchronization signal. Image acquisition of the digital image processing apparatus is performed by a CCD that converts light reflected from a subject into an electrical signal. In order to obtain a color image using a CCD, a color filter is required, and most of them employ a filter (not shown) called a color filter array (CFA). CFA has a structure arranged regularly by passing only one color light per pixel, and has various shapes according to the arrangement structure. The ADC converts an analog video signal output from the CCD into a digital signal.

The image processor 35 performs signal processing to display the digitally converted RAW data.

In addition, the digital image processing apparatus according to the present invention is not only a memory card storing the above-described image file, but also an EEPROM (Electrically Erasable and Programmable Read Only Memory) and a digital camera storing algorithms necessary for the operation of the processor of the digital image processing apparatus. Of course, it may further include a flash memory for storing the configuration data required for the operation of the processor. In addition, in the case of the present invention, a gesture storage unit (not shown) for storing various kinds of information according to the selection of the gesture graphic and the gesture operation may be further provided with respect to the gesture editing function.

Image files stored in the storage unit 37 are selected by the user's selection in the reproduction mode and reproduced on the display unit 23. For example, in the conventional touch-sensing-based digital image processing apparatus, gesture graphics for facilitating image reproduction have been used. However, such gesture graphics may be digital images regardless of the user's intention. Since the processing apparatus is manufactured, it has been made to perform the determined gesture operation.

As described above, in order to improve the mapping relationship between the gesture graphic and the gesture action that does not freely reflect the user's intention, the digital signal processor 39 according to the present invention may perform the gesture action selected by the user on the gesture graphic selected by the user.
