摘要： There is a film image information reading apparatus called a film scanner. This apparatus comprises: a lighting optical system to illuminate a film document; a photoelectric conversion element, such as a CCD to convert the image information of the film document into the electric signal; and an adjusting circuit to adjust the output of the photoelectrical conversion element such that a predetermined density of the film document is output as an output of almost the saturation level of that element. The predetermined density is the color density of the base color of a negative film. The adjusting circuit may control the charge storage period, gain, or output level of the photoelectric conversion element. With this apparatus, the positive image can be easily derived by reversing the negative image without considering the base color of the negative film and the image signal of a high quality can be obtained.

Reflected light from the object is received by a photo-electric converter to shift the position of a photo-taking lens to an in-focus position on the basis of a signal produced from the photo-electric converter.

摘要： In the disclosed distance measuring arrangement, a light projector turns on and off to illuminate an object over the ambient light during projection periods when light is projected and during space periods when light is not projected. The reflected light is detected as a function of distance by integrating projection signals representing light reflected during projection periods, integrating space signals representing light during reflected space periods, subtracting the integration space signals from the projection signals, and extracting measurements based on the subtractions. Compensation for change in ambient light between periods is obtained by changing the timing of the integrations and extractions from concidence with the projections and space periods.
