a buffer for recording the captured image and the taken image;
a first memory unit for recording the live view image; and
a second memory unit for recording the preview image;
wherein:
the captured image captured by the image taking unit is recorded in the buffer, and subsequently sent from the buffer to the first image processing unit;
the taken image created by the image taking unit is recorded in the buffer, and subsequently sent from the buffer individually to the second image processing unit and the third image processing unit;
the live view image created by the first image processing unit is recorded in the first memory unit, and subsequently sent from the first memory unit to the display unit;
the preview image created by the second image processing unit is recorded in the second memory unit, and subsequently sent from the second memory unit to the display unit; and
the display unit displays the live view image and the preview image together.
11. A method of taking an image comprising:
an image capturing step for capturing an image;
a taken-image creating step for creating a taken image;
a first image processing step for creating a live view image by using an image captured through the image capturing step;
a second image processing step for creating a preview image by using the taken image;
a third image processing step for saving the taken image; and
a displaying step for displaying the preview image in addition to displaying the live view image,
wherein at the time to end displaying the preview image, the displaying of the preview image is moved toward an icon representing a saving folder so as to be eventually drawn in the icon.
12. The method of taking an image according to claim 11 , wherein, after completion of the taken-image creating step, the image capturing step starts in parallel with the second image processing step.
13. The method of taking an image according to claim 11 , wherein, after a predetermined time period passes since displaying the preview image has started, the displaying step finishes displaying the preview image.
14. The method of taking an image according to claim 11 , further comprising a command sending step for sending an image-taking command signal, wherein:
the taken-image creating step carries out the creating process of a taken image according to an input of the image-taking command signal; and
if the image-taking command signal is sent out through the command sending step while the display screen is displaying the preview image, the displaying step discontinues displaying the preview image.
15. The method of taking an image according to claim 11 , wherein the displaying step displays the preview image in such a way that at least one of the transparency, shape, size, and position of the preview image changes in accordance with the passage of time.
16. The method of taking an image according to claim 11 , wherein, at the time of displaying the live view image and the preview image together, the displaying step displays one area for displaying the live view image and the other area for displaying the preview image separately.
17. The method of taking an image according to claim 11 , wherein, during execution of the taken-image creating step, the displaying step displays the live view image on the display screen, the live view image being created by using an image that the image capturing step has captured immediately before the start of the taken-image creating step.
18. The method of taking an image according to claim 11 , wherein the processing operation by the second image processing step for creating the preview image by using the taken image includes only a process for contracting the taken image.
