摘要： Several devices for determining a distance of an object a user of an electro-active lens is looking at are presented. Once the distance is determined, the devices may alter the optical power of the electro-active lens to ensure that the object is correctly focused. Optical range finding is a possible means for carrying out this task. An active rangefinder may emit optical radiation from a transmitter directed at the object. The optical radiation may then be reflected off the object. The reflected optical radiation may then be received with an appropriate receiver. The received optical radiation may then be processed by appropriate circuitry to determine a distance to the object. A passive rangefinder works without a transmitter. Instead, an appropriate receiver receives ambient sources of light from the object. The received light may then be processed by appropriate circuitry to determine a distance to the object.

摘要： A B S T R A C T An image processing circuit/CPU (6) performs AF processing in response to a halfway shutter operation and upon confirmation of a shooting shutter instruction causes the light emitting means in a flash circuit (11) to emit light, and decides the amount of light emitted at shooting time on the basis of the brightness component of an output signal of an imaging element (2), whereby a subject distance is calculated from the amount of light emitted at shooting time, wherein, when the in-focus decision in the AF processing is negative, an optical lens (1) is moved by a lens drive circuit (5) to the position corresponding to the subject distance which has been acquired on the basis of the amount of light emitted at shooting time and a shooting operation is then performed, so that, even if the focus decision is impossible with the phase-difference or contrast-based AF system disadvantageous to dark subjects, the optical lens (1) can be moved to the neighborhood of the correct in-focus position.

摘要： The present invention provides for very rapid autofocusing of optical scanning systems. If a sample is sufficiently out of focus, the focal error signal used to focus a conventional half-blocked system can become saturated. Multiple steps toward the focus position then typically are required to bring the system into the operational range. To minimize this, a light adjustment system is provided to reduce the amount of light impinging on the half-blocked system when the focal error signal is at or near saturation. The half-blocked system then becomes primary controller again, and can move the system into a position generally close to the correct focal point. The light adjustment system then can be deactivated, but since the system now is much closer to focus, the half-blocked system can quickly bring the system into final focus. Alternatively, the photodetectors used to generate the focal error signal are segmented. The approximate distance to the correct focal point then is determined by comparing the amount of light detected by segments at different radial positions.
