1. An electronic camera for electrically photographing a subject, comprising:
- preliminary illuminating unit configured to illuminate the subject with preliminary light rays;
exposure control section configured to control an exposure of an image relating to the subject illuminated with the preliminary light rays to generate image data;
extracting section configured to extract an block area or areas from the image data, the extracted block area or areas corresponding to a part or parts of the subject, which mainly illuminated with the preliminary light rays; and
setting section configured to set a predetermined white balance adjustment with respect to the block area or areas.

Abstract
There is disclosed a constitution in which an area with strobe light rays dominant therein, which corresponds to strobe light dominant area, is extracted in accordance with various extraction conditions, and a white balance adjustment suitable for a property of the area is set in order to enhance a result of an indoor strobe photographing. Moreover, it is judged whether or not correction is appropriate for each white balance area in accordance with a result of evaluation exposure of a steady light amount.

9. An electronic camera including a strobe, comprising:
-
preliminary exposure configured to perform a steady light preliminary exposure by steady light rays and perform a pre-flash preliminary exposure accompanied by a strobe light illumination in response to a photographing preparation operation;
judgment section configured to judge whether a image area influenced dominantly by strobe light rays exceeds a predetermined ratio with respect to a whole exposure image area based on a steady light preliminary exposure result and pre-flash preliminary exposure result; and
white balance setting section configured to apply a white balance condition for the strobe light rays different from a white balance condition for steady light rays to an area influenced dominantly by said strobe light rays during a strobe photographing, when said judgment means judges the area influenced dominantly by the strobe light rays to exceed the predetermined ratio with respect to the whole exposure image area. - View Dependent Claims (10)

11. An exposure method of an electronic camera including a strobe, comprising the steps of:
-
performing a steady light preliminary exposure by steady light rays and performing a pre-flash preliminary exposure accompanied by a strobe light illumination in response to a photographing preparation operation;
judging whether a image area influenced dominantly by strobe light rays exceeds a predetermined ratio with respect to a whole exposure image area based on a steady light preliminary exposure result and pre-flash preliminary exposure result; and
applying a white balance condition for the strobe light rays different from a white balance condition for steady light rays to an area influenced dominantly by said strobe light rays during a strobe photographing, when said judgment step judges the area influenced dominantly by the strobe light rays to exceed the predetermined ratio with respect to the whole exposure image area. - View Dependent Claims (12)
