At step S207, display control unit 227c obtains the coordinate (step S207) of touch location, make display part 216 on live view image, show zoom frame (step S208), and sub-picture is overlapped on live view image and in display part 216, shows (step S209).Specifically as shown in figure 11, by touch panel 217, in the situation that carried out on the live view image W10 that display part 216 shows touching, display control unit 227c shows zoom frame K10 to the Nei region, cornerwise position that comprises 2 touch locations.And the right part that the sub-picture K11 that intercepts the region of zoom frame K10 by the 207a of cutting portion from view data and generate is overlapped in to live view image W10 shows.User can grasp photography region after zoom and the image after zoom thus.After step S209, camera head 1 is transferred to step S210.
Illustrate that display control unit 227c is overlapped in zoom frame K10 the computational methods of the viewing area while showing on live view image W10 herein.To be explanation display control unit 227c be overlapped in the figure of the computational methods of the viewing area while showing on live view image W10 by zoom frame K10 to Figure 12.In Figure 12, can consider following coordinate system: take the lower-left of display part 216 is initial point, and what take display part 216 is laterally X-axis, and what take display part 216 is longitudinally Y-axis.
As shown in figure 12, to establish the size of display part 216 in X-direction be X(f), zoom frame is in the situation that the size of X-direction is X(fmax), the focal length of current camera lens part 3 is that the maximum focal length of F, camera lens part 3 is Fmax, can pass through following formula (1) and calculate zoom frame in the indication range of X-direction.
X（fmax）=（X（f）×F）/Fmax…（1）
In addition, to establish the size of display part 216 in Y direction be Y(f), zoom frame is in the situation that the size of Y direction is Y(fmax), the focal length of current camera lens part 3 is that the maximum focal length of F, camera lens part 3 is Fmax, can pass through following formula (2) and calculate zoom frame in the indication range of Y direction.
Y（fmax）=（Y（f）×F）/Fmax…（2）
Like this, display control unit 227c is used formula (1) and formula (2), calculates live view image W10 and goes up the big or small X(fmax of the viewing area of zoom frame K10), Y(fmax).
Return to Figure 10, continue the later explanation of step S210.In step S210, touch test section 227a and detect whether zoom frame K10 has been carried out to slide.Touch test section 227a and detect (step S210: be) in the situation of the slide of zoom frame K10, camera head 1 is transferred to step S211 described later.On the other hand, touch test section 227a and do not detect (step S210: no) in the situation of the slide of zoom frame K10, camera head 1 is transferred to step S214 described later.
In step S211, display control unit 227c obtains expression and from having carried out the starting position of slide, plays the slip coordinate (step S211) that end slide user's finger has left the position of touch panel 217, makes display part 216 on live view image W10, show the zoom frame K10(step S212 corresponding with slip coordinate).And, sub-picture K11 is overlapped in to live view image W10 and above in display part 216, shows (step S213).As shown in figure 13, in the situation that zoom frame K10 has been carried out amplifying the slide of zoom ratio, display control unit 227c dwindles the viewing area of zoom frame K10 and shows in display part 216 according to slide example.And, the sub-picture K11 that intercepts the region of zoom frame K10 and generate is overlapped in to live view image W10 above in display part 216, shows by the 207a of cutting portion from view data.Thus, user can grasp photography region after zoom and the image after zoom.After step S213, camera head 1 is transferred to step S214.
Return to Figure 10, continue the later explanation of step S214.In step S214, release-push 211b has been carried out in the situation of half push (step S214: be), while showing zoom frame K10 on the live view image W10 showing at display part 216 (step S215: be), display control unit 227c deletes sub-picture K11(step S216 from live view image W10).
Then, photography control part 227b makes camera lens part 3 carry out optical zoom, until become the size (step S217) that is equivalent to zoom frame K1.Particularly, photography control part 227b is scaled the focal length of the camera lens part 3 corresponding with the viewing area of zoom frame K10 on live view image W10, the focal length that drives camera lens part 3 to obtain to become this conversion.
