摘要： An image of a subject is focused on an image pickup device through a zoom lens and a diaphragm. The image focused on the image pickup device is photoelectrically converted into an electric signal. The electric signal as a picture signal is supplied to an amplifying circuit. The amplifying circuit amplifies the supplied picture signal. The amplified picture signal is digitized by an A/D converter. The digitized picture signal is supplied to a signal processing circuit. The signal processing circuit performs a clamping process, a color signal process, a luminance signal process, and other processes such as contour compensation, defect compensation, and white balance compensation. A camera CPU controls the zoom lens through a lens driving circuit, controls the image pickup device through a timing generating circuit, and controls an auxiliary lighting portion 7. A signal received from an operating portion is supplied to the camera CPU.

摘要： A light-emission control apparatus comprising a light-receiving element 2, an A/D converting section 6, an integrating section 7, a comparing section 8, and a control section 9. The light-receiving element 2 outputs a light-reception signal corresponding to an amount of light it has received. The A/D converting section 6 converts the light-reception signal to digital data. The integrating section 7 integrates the digital data, generating an integrated value. The comparing section 8 compares the integrated value with a predetermined threshold value. The control means outputs a light-emission stop request to a light-emitting device 11, thereby causing the device 11 to stop emitting light, when the integrated value reaches the predetermined threshold value.
