摘要： An image acquisition apparatus includes: an imaging device on which an image of a small area allocated to an area to be imaged is formed; a detection section detecting intensity of light irradiated on the small area from a light source; an integration section integrating the intensity of light detected by the detection section; if an integration value of the intensity of light integrated by the integration section from a point in time when light is emitted from the light source is greater than a predetermined threshold value, a light-source control section terminates light emission; an exposure control section starting exposure of the imaging device before light is emitted from the light source and terminating exposure of the imaging device after emission of light from the light source is terminated; and an image acquisition section acquiring the image of the small area as a divided image from the imaging device.

摘要： A generator for a flash device includes at least a first capacitor bank, which includes at least one capacitor of a first type and at least a second capacitor bank, which includes at least one capacitor of a second type. The first capacitor bank is connectable to a charger via a first switch and the second capacitor bank is connectable to a charger via a second switch. The generator is configured to individually control the first switch and the second switch so that the first capacitor bank and the second capacitor bank can be individually charged to the same or different voltages. Since the first capacitor bank and the second capacitor bank can be simultaneously discharged, it is possible to achieve a desired energy level and color temperature from a flash device connected to the generator.

摘要： The invention relates to a light flash generator that comprises a discharge lamp (1), a DC supply circuit (6) for the discharge lamp capable of generating a voltage V2 between the anode (2) and the cathode (3), a priming circuit (5) for the discharge lamp (1) capable of applying a priming electric pulse (5’) on the priming electrode (4) of the discharge lamp, a main discharge circuit (7) capable of storing and discharging the electric energy necessary for generating one or more electric discharges with an intensity of 13 in the discharge lamp (1). According to the invention, the light flash generator includes a pre-expansion circuit (8) connected between the anode (2) and the cathode (3) of the discharge lamp (1). The pre-expansion circuit (8) is capable of generating an electric pre-pulse with an intensity of 14 at a voltage V4 in the discharge lamp (1), after the generation of the fine ionised flow (25) having an intensity of 12 and before the generation of one or more main light pulses in the discharge lamp (1), generating a light pre-pulse in the discharge lamp (1) for a duration of t4’.

摘要： The present invention relates to a photographing device that obtains color image signals of a subject image captured with a taking lens and an imaging device. The photographing device comprises a white light emitting diode (93) that is used as a light source of the photographing device and emits white light, a light emission control device (54) that makes the white light emitting diode emit light by supplying electric energy to the white light emitting diode, and an automatic white balance correcting device that corrects a white balance of the color image signals according to a color temperature of the white light emitted from the white light emitting diode at the light emission of the white light emitting diode.
