Fig. 4 is based on the 2nd example of the picture of photography/image quality variation of parameter operation.In addition, same with above-mentioned explanation, in the following description, the example of omission and image quality relating to parameters describes with the example relevant with photographic parameter.Fig. 4 (1) illustrates following scene: show the displaying live view image identical with Fig. 3 in the picture 40 of display part, finger 42 touches face's part 52 of the women in picture left side.In addition, under the situation of image quality control, do not carry out the demonstration of initial automatic mode.
Fig. 4 (2) is illustrated near the scene of the icon 54 of the photographic parameter that shows " women " the specified subject.By the subject detection 11d of portion, from view data integral body, extract the part of specified subject, be judged as the face of the kind of the subject that extracts for the women.Then, select the photographic parameter of " women " by parameter selection portion 11c.
In Fig. 4 (3), after in Fig. 4 (2), for example having shown about one second people's the icon 54 of photographic parameter, the demonstration of mode icon 50 is switched to " women's face ", and, as the photographic parameter modification information, at picture lower right display parameters window (Parameter window) 70.In parameter window 70, show the photographic parameter modification information uniformly.
And, position display cursor 56 in specified subject (women's face).In addition, in above-mentioned the 1st example, the demonstration example that icon 54 vivo moves to mode icon is shown, still,, the example that omits the animation that moves is shown here, still, yes arbitrarily.
Here, the photographic parameter of establishing " women " has the smooth and lightness of face to adjust these two adjustment parameters.The smooth of face is meant, carries out image processing and is adjusted into smooth with the skin with face.Particularly be following processing: by image processing part 17, detect the color spot of face and the part of fold, the data around utilizing are carried out interpolation so that this part is not obvious.The lightness adjustment is the processing of adjusting the brightness of face's part, by image processing part 17, increase and decrease face particularly the skin part luminance component and adjust.
In parameter window 70, at first show as the information relevant with the smoothness of face, expression adjusts the parameter name 72 that content is " face smooth "; As parameter guide 73 operation relevant, that simulated people's face (circle) with the smoothness of face; The adjusted value 74 of representing the circular shape of the current adjustment amount relevant with the smoothness of face.And then, in parameter window 70, show as with lightness adjust relevant information, to adjust content be the parameter name 76 of " lightness adjustment " in expression; As adjusting relevant parameter guide 77 operation, that simulated the craspedodrome bar with lightness; The adjusted value 78 (wedge shape) of the current adjustment amount that expression is relevant with the lightness adjustment.Adjust " smoothness of face " by the rotary manipulation shown in the direction of operating d around the parameter guide 73.By clockwise rotary manipulation, smooth amount increases.Operate by the craspedodrome about shown in the direction of operating e of parameter guide 77 and to adjust " lightness adjustment ".By operating to right, face is brighter.
Fig. 4 (4) is the picture that the above-mentioned parameter alter operation finishes.For example by at the operation of the double-click of picture etc., promptly determine the operation of cameraman's change, the parameter window 70 that deletion is showing, parameter modification EO.According to the icon display of photograph mode, the situation that photograph mode changes to the photographic parameter of " women " is shown.
Fig. 5 is the example that has utilized the other forms of parameter window of parameter window.Be following scene: as subject, specified the apple of picture central authorities belows, be judged as subject by the subject detection 11d of portion and be " apple ", by parameter selection portion 11c, according to " apple ",, selected the photographic parameter of " cooking " as photographic parameter.Then, by display control unit 18, at the screen displayed parameter window 80 relevant with corresponding cooking.
If the photographic parameter of " cooking " has form and aspect, chroma, these three of lightness to adjust parameter.In the parameter window 80 relevant, show this three parameters uniformly with cooking.In parameter window 80, in accordance with the order from top to bottom, configuration and form and aspect, chroma, relevant each parameter name 82 and the horizon bar of lightness are parameter guide 84.The current adjusted value of cursor 86 expressions of each the dark circles shape on the parameter guide 84.Here, on parameter window 80, with three parameter guides 84 of proper spacing alignment arrangements, so the operator can utilize an operation to set three parameters so that finger is operated to the mode that direction of operating f slides on picture.Certainly, the operator also can change adjusted value singly to operate along the mode of parameter guide 84 horizontal slip cursors 86.
Fig. 6 is the example of parameter window that has utilized the another form of parameter window.If specified subject and the 1st example identical " setting sun ".In this example, the photographic parameter of " sunset clouds " is different with the 1st example, adjusts these two parameters by color adjustment and chroma and constitutes.
Fig. 6 (1) is following scene: specified " setting sun ", photograph mode changes to the photographic parameter of " sunset clouds " from automatic mode.In the 1st example, automatically in screen displayed parameter guide (Fig. 3 (1)), still, in this example, hide the major part of parameter window 90, only show a part at the picture right-hand member, under the situation of the operation of having carried out the operator, the integral body of parameter window 90 appears in picture.This is for preferential visuognosis displaying live view image.
Fig. 6 (2) is following state: with the operator's of the end of the parameter window of direction slip left 90 operation correspondingly, by display control unit 18, display parameters window 90 animation of moving of direction left on picture is in the integral body of the parameter window 90 of screen displayed sunset clouds.
In parameter window 90, dispose the project that chroma is adjusted in the adjustment of left side configuration color, on the right side.About the color adjustment, show the color adjustment usefulness of ring-type parameter guide 93, represent wherein parameter name 92 and adjusted value (currency is 7) 94 for the color adjustment.About the chroma adjustment, show equally the chroma adjustment usefulness of ring-type parameter guide 97, represent wherein parameter name 96 and the adjusted value (currency is 60) 98 adjusted for chroma.
When the operator when each parameter guide is carried out rotary manipulation shown in the b, photography conditions configuration part 11a changes the adjusted value that color adjustment and chroma are adjusted according to its operational ton.By clockwise rotary manipulation, all be adjusted into this value and increase.Fig. 6 (3) is illustrated in half the state of parameter window 90 of screen displayed.Under the situation that only needs color to adjust, the operator can utilize finger prick that the slide of left and right directions is adjusted, so that parameter window 90 exposes the amount of the parameter guide 93 of display color adjustment usefulness in picture.
Fig. 7, the 8th illustrates the flow chart of operating the flow process of relevant processing with the photography/image quality variation of parameter of above-mentioned explanation.
Fig. 7 is the flow chart of processing that the alter operation of photographic parameter is shown.The processing of the alter operation of photographic parameter waits and carries out by control part 11, photography conditions configuration part 11a, parameter selection portion 11c, the subject detection 11d of portion, operation detection part 11e, display control unit 18.Part or all of control part 11, photography conditions configuration part 11a, parameter selection portion 11c, the subject detection 11d of portion, operation detection part 11e, display control unit 18 etc. is called the photography conditions control device.
