摘要： In a module which consists of optical systems and sensors, a pair of first line sensors are arranged vertically to a pair of second line sensors, and each of the line sensors is provided with a lens which projects an object image thereon. One of the first line sensors and one of the second line sensors intersect each other at right angles, and share an object lens which projects an object image onto them. In such a construction, the number of lenses, and the space for the line sensors are reduced, so that the module can be downsized.

摘要： A distance measuring apparatus includes a pair of line sensors. An image of an object is projected on the line sensor through a lens. The distance up to an object is measured according to the object image in the line sensor. The line sensor includes a plurality of pixels (CCD). The time period for respective pixels to complete charge accumulation with the pixel first completing charge accumulation as the pixel of quantizing reference becomes the data for the respective pixels. In the present invention, the range of pixels used for quantizing reference is altered according to variation in the focal length of the lens. The operation of distance measurement is terminated when charge accumulation for all the pixels within the range of the integration completion determination ends. The range of integration completion determination is altered according to the focal length, the measured brightness value and the shooting mode.
