Abstract: An illumination control unit selectively turns on strobe devices and a strobe light emitting unit. An image acquisition unit captures an image of an object through an imaging element and acquires individual illumination images. An individual irradiation area detection unit detects individual irradiation areas which are areas irradiated with each illumination light component in the imaging range of the imaging element on the basis of the individual illumination images. An irradiation area image generation unit generates an irradiation area image obtained by inserting division marks indicating each individual irradiation area into the image of the object. An irradiation area image output unit displays the irradiation area image on a rear display unit. The user observes the irradiation area image and can simply recognize each individual irradiation area.

Abstract: In a variable magnification viewfinder device, information displayed on a liquid crystal panel and a viewfinder image are combined with each other through a prism. When a variable power lens is inserted in a viewfinder optical path, viewfinder magnification is changed. Based on the change in the viewfinder magnification, brightness of a backlight unit is changed and luminance of the information displayed on the liquid crystal panel is changed. In a viewfinder field of view, the information and the viewfinder image are displayed at substantially the same brightness.

Abstract: An image shooting device includes an image shooting component, a brightness detector, a flash component, a shift detector, a controller, and a flash amount determining component. The shift detector detects a shift amount of a subject position in a set of image data that has arisen due to shaking of the image shooting device. The controller corrects, on the basis of the detected shift amount, at least one of two sets of image data acquired within non-flash state and flash-emitting state, such that positions of a detection target region with respect to the subject position of the respective sets of image data are substantially matched. The flash amount determining component determines a flash amount of the flash component on the basis of the detected brightness level.

Abstract: An imaging apparatus includes: flash driving means for driving a flash during a set preliminary emission period and a set main emission period; and an image sensor constituted by a plurality of photoelectric converting elements which are arranged in a matrix and capable of being accessed randomly. The charge accumulation initiation timing and the charge accumulation cessation timing of the photoelectric converting elements line are controlled line by line or pixel by pixel. The imaging apparatus forms images employing pixel signals output from the photoelectric converting elements, and determines main regions within the images. The preliminary emission period is set such that charge accumulation in photoelectric converting elements corresponding to pixels that constitute the main region is initiated prior to the preliminary emission period and ceased after the preliminary emission period. The flash driving means drives the flash during the set preliminary emission period.

The charge accumulation initiation timing and the charge accumulation cessation timing of the photoelectric converting elements are controlled line by line or pixel by pixel. The imaging apparatus forms images employing pixel signals output from the photoelectric converting elements, and extracts pixel signals output from photoelectric converting elements in which charge accumulation is initiated prior to the preliminary emission period and ceased after the preliminary emission period. An emission amount to be employed during the main emission period is determined by executing predetermined calculations based on the extracted pixel signals. Main emission of flash is performed with the determined emission amount.

Otherwise, it obtains both of them. The emission control unit determines the emission amount for the main emission using one of the obtained face detection results.
