Abstract: In a camera having a gamma-correction circuit on an output signal processing path of a CCD, an incident light path leading to the CCD is kept opening in a state where nonlinear gamma-correction processing in the gamma-correction processing circuit is prohibited, first image data (CCD output data; DATA1) are generated based on electric signal output from the CCD, incident light path leading to the CCD is kept closing, second image data (CCD output data; DATA2) are generated based on electric signal output from the CCD and lastly, the second image data DATA2 are subtracted from the first image data DATA1, thereby correcting to eliminate dark voltage component included in the first image data DATA1.

Abstract: A flash device is provided which causes a plurality of light emitting elements to emit desired white strobe light independent of possible uneven brightnesses of light being emitted by light emitting used. Red, green and blue light emitting elements are driven to emit corresponding colored rays of light to thereby provide white strobe light. Percentages of respective total light emission times of the light emitting elements are determined depending on the percentage data of light being emitted by those light emitting elements and stored in memory.
Abstract translation: 提供一种闪光装置，其使得多个发光元件发射期望的白色闪光灯，而与所发光的发光的可能的不均匀亮度无关。 红色，绿色和蓝色发光元件被驱动以发射相应的彩色光线，从而提供白色闪光灯。 发光元件的总发光次数的百分比取决于由这些发光元件发射的光的百分比数据并存储在存储器中。
