    摘要： There is provided a charging device capable of improving charging efficiency and reducing power consumption, thereby increasing a battery service life. The charging device charges a main capacitor (2) by rectifying output voltage boosted via a self-excitation DC-DC converter, by using a diode (D). The self-excitation DC-DC converter is configured as follows. When a current value (I1) flowing in a primary side (P) of an oscillation transformer (T) reaches a first predetermined value (IPK1) the excitation period is terminated and energy is transmitted from the primary side (P) to the secondary side (S) of the oscillation transformer (T) so as to execute a charging period for charging the main capacitor (2). The excitation period is resumed with a delay time (t1) after detecting that the current value (I2) flowing into the secondary side (S) of the oscillation transformer (T) is lowered than a second predetermined value (Ith2).

    摘要： The present invention provides a flash discharging circuit for simplifying the charging of electric power in a capacitor. When energy discharged from a transformer for storing and discharging energy is charged in a main capacitor of the circuit, a detection voltage inputted to a first input terminal of a comparator so as to detect a primary current flowing through a primary winding of the transformer is compared with a reference voltage inputted to a second input terminal of the comparator. According to a result of the comparison, it is detected that a predetermined primary current flows through the primary winding of the transformer. When the primary current flowing through the primary winding of the transformer is turned off, the reference voltage is set to be lower than the detection voltage.

    摘要： An improved handheld electronic device and camera apparatus upon which can be executed an improved method enable a modular camera to be used in conjunction with a flash. In one implementation, compensation parameters that are intended for use in a non-flash situation are overwritten with compensation parameters that are configured to compensate for the combined effects of the camera and the flash and are used by an embedded compensation routine executed on the camera. In another implementation, an image signal is processed by the embedded compensation routine using the original compensation parameters, but if it is determined that the image signal is a flash image signal, the image signal is further processed by the embedded compensation routine employing an additional set of parameters which compensate the image signal for the effect of the flash.

    摘要： A camera includes: a photometric unit that acquires two dimensional photometric information of an image of a photographic subject; a separation unit that separates the image of the photographic subject into two groups, based upon photometric information acquired by the photometric unit during non-emission of light by a flash light emission device; and a calculation unit that multiplies the photometric information acquired by the photometric unit during a first light emission by the flash light emission device before photography, by different coefficients for the two groups, and calculates an amount of light required for photography that is to be emitted during a second light emission by the flash light emission device, based upon the photographic information after multiplication by the coefficients.
