Abstract

A photographing apparatus comprises an imaging sensor and a display unit. The imaging sensor obtains image data. The display unit indicates a first white balance setting picture that is used for setting a white balance gain in a white balance adjustment of the image data and a second white balance setting picture that is used for setting a fine adjustment of the white balance gain. The second white balance setting picture has an adjustment state indication area that illustrates a state where the fine adjustment is tuned and an adjustment quantity indication area which has a cursor illustrating a quantity of the fine adjustment and a two-dimensional coordinate plane illustrating a range of movement of the cursor. Only the second white balance setting picture has the adjustment state indication area.

Claims (21)

1. A photographing apparatus comprising:

an imaging sensor that obtains image data; and

a display unit that indicates a first white balance setting picture that is used for setting a white balance gain in a white balance adjustment of said image data and a second white balance setting picture that is used for setting a fine adjustment of said white balance gain, said second white balance setting picture having an adjustment state indication area that illustrates a state where said fine adjustment is tuned and an adjustment quantity indication area which has a cursor illustrating a quantity of said fine adjustment and a two-dimensional coordinate plane illustrating a range of movement of said cursor;

only said second white balance setting picture having said adjustment state indication area;

wherein in said fine adjustment of said white balance gain, an adjustment of tone of colors between green and magenta, and an adjustment of tone of colors between blue and amber, are tuned;

said adjustment state indication area having a first adjustment state indication area, a second adjustment state indication area, a third adjustment state indication area, and a fourth adjustment state indication area;

said first adjustment state indication area being arranged on an upper side of said adjustment quantity indication area;

said second adjustment state indication area being arranged on a lower side of said adjustment quantity indication area;

said third adjustment state indication area being arranged on a right side of said adjustment quantity indication area; and

said fourth adjustment state indication area being arranged on a left side of said adjustment quantity indication area.

2. The photographing apparatus according to claim 1 , wherein

said first adjustment state indication area has an arc shape;

said second adjustment state indication area has an arc shape;

said third adjustment state indication area has an arc shape;

said fourth adjustment state indication area has an arc shape; and

said first, second, third, and fourth adjustment state indication areas approximately form a circular shape that surrounds said adjustment quantity indication area.

3. The photographing apparatus according to claim 1 , wherein a square-shaped frame that constitutes an external form of said two-dimensional coordinate plane, has an upper-side part, a lower-side part, a right-side part, and a left-side part;

said upper-side part has green color at a horizontal center, has a color gradation so that amber color is increased in a right direction from green color at said horizontal center, and has a color gradation so that blue color is increased in a left direction from green color at said horizontal center;

said lower-side part has magenta color at said horizontal center, has a color gradation so that amber color is increased in said right direction from magenta color at said horizontal center, and has a color gradation so that blue color is increased in said left direction from magenta color at said horizontal center;

said right-side part has amber color at a vertical center, has a color gradation so that green color is increased in an upper direction from amber color at said vertical center, and has a color gradation so that magenta color is increased in a lower direction from amber color at said vertical center; and

said left-side part has blue color at said vertical center, has a color gradation so that green color is increased in said upper direction from blue color at said vertical center, and has a color gradation so that magenta color is increased in said lower direction from blue color at said vertical center.
