摘要： The present invention provides an image capturing apparatus capable of properly zooming in on a main subject without performing complicated framing. A digital camera having an electronic zoom function has an external passive type distance detector for obtaining two-dimensional distance detection information. The two-dimensional distance detection information obtained by the distance detector is used for an auto-focus control of the digital camera. Further, the two-dimensional distance detection information is also used for detection of a main subject in an image capturing area. The digital camera specifies the position of the main subject by using the two-dimensional distance detection information and moves the center of the partial area to be extracted in the case of generating a pseudo zoom image toward the specified position.

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.

摘要： When an FFP mode is set, a quick-return mirror and a sub mirror are driven between an inclined position and a horizontal position according to whether the focus point is within the image capturing area of a phase difference AF module or not. When the focus point is set within the image capturing area of the phase difference AF module, focus adjustment is performed by a phase difference detection method using the phase difference AF module. When the focus point is set outside the image capturing area of the phase difference AF module, focus adjustment is performed by a contrast detection method with the entire image capturing area as the object area of the focus adjustment.

摘要： A camera including a first and second luminance detector, a distance detector and a calculator. The first luminance detector, having a first spectral sensitivity and receiving light from a larger region of a photographing view, generates a first luminance information. The distance detector, having a second spectral sensitivity and receiving light from a smaller region of the photographing view, generates a distance information concerning a distance to an object. The second luminance detector generates a second luminance information based on the received light of the distance detector. The calculator calculates a control luminance value for exposure control based on the first luminance information and the second luminance information when the first luminance information is above a predetermined threshold value. In addition, the calculator calculates a control luminance value based on the first luminance information when the first luminance information is below the predetermined threshold value.

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.
