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： A rangefinder provides a rangefinding optical system, and photoreception unit including a pair of photoelectric conversion element arrays, and outputs signals corresponding to the light received by the photoelectric conversion element arrays. The controller allocates the output signals o a plurality of areas, and stores signals included within a single allocated area in memory. The memory has a storage capacity sufficient only to store the allocated data. Data relating to the distance to a rangefinding object are determined by calculations using the data stored in memory.

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 metering device includes a pair of image sensors, and a pair of optical members. Each image sensor has a number of pixels arranged along a specified direction. There is provided a distance data calculator for defining a plurality of pairs of meter areas over pixels of the first and second image sensors, and calculating distance data concerning a distance to the object by performing a plurality of comparisons between image data from a pair of meter areas by shifting the pair of meter areas relative to each other a set number of pixels. A shift pixel number for a particular pair of meter areas having a smallest spatial parallax with respect to an optical axis of an optical system of a viewfinder is made to be different from that for the other pairs of meter areas.

摘要： An object detecting apparatus according to the present invention has: an image sensor capturing a plurality of object images in time sequence; a first detection start signal generator generating a signal to start detection of an object, included in a first area, of the object images captured by the image sensor; a first detector detecting a characteristic of the object included in the first area in response to the signal from the first detection start signal generator; and a second detector detecting an object similar to the characteristic detected by the first detector, within a second area larger than the first area. Consequently, even when a moving object is shot, the user can take a picture intended by him only by determining the composition so that the main object is roughly followed.
