摘要： A photographic camera in which a two-position lens is focused automatically on subjects located within "near" and "far" distance ranges from the camera. The lens is normally positioned in one of the two positions and movable to the other of the two positions in response to a signal generated by an electronic ranging circuit upon the detection of subject location in the focus range to which the other position corresponds.

摘要： At least one image of a moving object is acquired using an image acquisition device equipped with an automatic focussing system. A distance between the object and the device when the effective acquisition of the image occurs is estimated based on the estimated speed and on the period of time separating a time of actuation triggering the process for acquiring the at least one image from the time of acquisition of the said effective acquisition, and the taking into account of the said distance by the automatic focussing system.

摘要： Systems and methods for generating an optical image include forming an optical image with at least one optical element of an optical imager while modifying wavefront phase. Modifying the phase does not reduce an optical bandpass limited by an aperture of the optical imager. The systems and methods also include detecting the optical image over a range of spatial frequencies such that there are no zeros in an optical transfer function of the optical imager over detected spatial frequencies within the optical bandpass and over an extended depth of focus that is larger than a depth of focus occurring without modifying wavefront phase.

摘要： A photographic exposure control system automatically classifies ambient scene lighting conditions as normal, backlit or forelit and then selects an exposure parameter signal program that is appropriate for the indicated conditions. The system monitors a plurality of different portions of the scene area with a multi-sensor array that detects both subject range and ambient light intensity. A comparison of range measurements identifies that scene area portion having the nearest subject therein as the subject area. Ambient light intensity measurements of subject and non-subject areas are compared to classify lighting conditions and select a corresponding one of normal, backlit and forelit signal programs which control operation of system components to vary the ratio of ambient to artificial light contribution to exposure for the indicated lighting conditions.
