A charger includes a power obtaining unit and a power transfer unit. The power obtaining unit charges a first power storage device with a voltage supplied from outside. The power transfer unit transfers power stored in the first power storage device to a second power storage device so as to store the power in the second power storage device. The power transfer unit includes a voltage decrease reduction unit. The voltage decrease reduction unit reduces voltage decrease of the first power storage device per transfer of the power from the first power storage device to the second power storage device. The second power storage device has a capacitance larger than the first power storage device.

In an imaging apparatus having LEDfor emitting light toward an object, an imaging unithaving CCDgenerates a first object image with LEDemitting light and a second object image with LEDemitting no light. Average brightness of the first object image and average brightness of the second object image are calculated. Brightness difference between the average brightness of the first object image and the average brightness of the second object image is calculated. Brightness difference of the object is obtained using the calculated brightness difference between the first and second object images, and under control of CPU, a process is executed for adjusting exposure conditions based on the brightness difference of the object.

In a video creation device, a creator creates a frame of a first type and a frame of a second type. A difference determiner determines whether or not the difference between frames of a determination pair exceeds a threshold, wherein the determination pair contains two frames of the first type, or the frame of the first type and the frame of the second type. A frame creator creates a frame of a third type between frames of a data pair, wherein the data pair contains two frames of the first type next to each other. A synthesizer creates high-dynamic-range frame by synthesizing frames of synthesized pair, wherein synthesized pair contains the frame of the second type and the frame of the first type, or the frame of the second type and the frame of third type. And, a video creator creates video comprised of the frame synthesized by the synthesizer.

When a hand shake reducing mode has been set for shooting a subject, an exposure is controlled in accordance with a program diagram (solid line) B for the shake reducing mode, which is different from a program diagram (broken line) A for a normal mode. In a state where a shutter speed is set to less than ' 1/80', two-pixel addition and/or four-pixel addition is executed on an imaging signal to amplify subject luminance, raising ISO sensitivity. A shutter speed set to fall in a high speed range reduces deterioration in image quality due to hand shake and/or subject movement during a shooting operation.

When picking up an image including an object, an imaging apparatus displays the picked-up image on a display unit, and stores the image in a first storage unit. Then, the imaging apparatus performs such control as to extract the contour of an object image in the image stored in the first storage unit, and to display the contour together with the object image on the display unit. A first correction unit then corrects the object image, from which the contour is extracted, into a circular shape, and the corrected object image is stored in a second storage unit.

An image capturing apparatus includes a power source controller for controlling a power supply to the image capturing apparatus to be in one of: (i) an on state, and (ii) an off state. A detector detects when any one of a plurality of operation members of the image capturing apparatus is operated when the power supply is in the off state. A brightness acquiring section controls an image capturing unit of the image capturing apparatus to acquire a brightness of an environment of the image capturing apparatus, when the detector detects that one of the operation members has been operated when the power supply is in the off state. A determining section determines whether or not the acquired brightness is above a predetermined level. And an image capturing controller permits the image capturing unit to capture an image of a subject only if the determining section determines that the acquired brightness is above the predetermined level.

When an auxiliary emission auto focus has been set by operation and through image display is started, a CPUstarts an operation of acquiring a single frame among those sequentially picked up at a predetermined interval. Next, the CPUcalculates an EV value, judges whether a LEDstate. If the LEDis in the ON state, the CPUjudges the calculated EV value. If the EV value is equal to or more than EV, the CPUimages a single frame after temporarily turning OFF the LED, and then turns the LEDON to judge whether the shooting scene is really dark. Next, the CPUcalculates the EV value. When judged that the EV value is not equal to or less than EV, the CPUjudges that the shooting scene is not dark and turns OFF the LED

There is provided an illumination apparatus used for imaging a moving picture made up of a plurality of frames, and for irradiating an auxiliary light from a light source constituted by one or a plurality of LEDs onto a photo-object. The one or plurality of LEDs are duty-driven by a duty ratio smaller than 100% during an imaging period (during a period for exposing a CCD) of a frame period. The heat releasing effect and the light emitting efficiency can be improved as compared to a case where the LEDs are successively turned on during an imaging period. As a result, the light emitting intensity at the time the light emitting diodes are turned on can be heightened with the amount of consumed electricity unchanged, and the light emitting efficiency of the light emitting diodes can be improved.
