Abstract: Auto focus control is exerted based on a focus evaluation value indicating a degree of sharpness of an image obtained from a plurality of image pickup devices placed at positions of different light path lengths. There is provided a device which makes a correction on sensitivity of the focus evaluation value obtained from each image pickup devices. It is thereby possible to make an adequate correction on a sensitivity of the focus evaluation value so as to exert the auto focus control with high accuracy. It is also possible to automatically make a correction on the sensitivity of the focus evaluation value and eliminate troublesome labor. All or a part of signal processing for the auto focus control is performed by a single processing part by time-sharing. Thereby, a circuit scale can be miniaturized and power consumption can be reduced.

Abstract: In a lens system in which a momentary mode in which AF is operated when an AF switch SW2 is pressed and a continuous mode in which the AF is continuously operated can be selected, a CPU uses the AF switch SW2 for use in the momentary mode as an AF stop switch, and stops an AF process when the AF switch SW2 is pressed (turned on) in the continuous mode.

Abstract: A communication navigation apparatus (102) predicts a planned en route point that may deviate from a guidance route and previously connects a communication line for connection with a communication server (101). For example, when current waypoint information (P) is positioned on a link (L2), the apparatus extracts a node (V2) as en route point information and connects a communication line with the communication server (101). If the current waypoint information (P) is positioned on a link (L3) after the apparatus passes the node (V2), it means that the apparatus is not deviated from a guidance route corresponding to guidance route information (R), so that it cuts the connected communication line.

Abstract: A focus detecting system for determining the focus state of an imaging lens, such as a camera lens, is disclosed. Object light not forming an image for image production is deflected along an optical axis through a relay lens to a focus state detection unit that includes image detecting elements with light receiving surfaces that are equidistant in front of and behind a position conjugate with a light receiving surface for image production. Either the relay lens or the focus state detection unit is moveable along the optical axis to vary how far the light receiving surfaces are out of focus. A diaphragm opening of the imaging lens determines if and by how much the relay lens and focus state detection unit are relatively moved. Evaluation values of the out of focus amount are compared in order to control focusing of the imaging lens.

Abstract: The object distance display apparatus displays object distances according to actually measured object distance data entered in advance, matched with focusing lens positions acquired from a television lens device, and enables, when the apparatus is connected to the television lens device, any data entry error to be readily identified by graphically displaying the object distance data entered in advance. Actually measured object distance data entered in advance, matched with focusing lens positions, can be graphically displayed on an LCD panel with a touch panel function of the apparatus. If any abnormal datum such as an input error is detected, it can be deleted by touching a delete switch.

Abstract: In a substrate treating unit, a removal liquid supplying mechanism supplies a removal liquid to the surface of a substrate. In order to retain the removal liquid on the surface of the substrate for a fixed time, a spin chuck is operated to spin the substrate at such a low speed as to retain the removal liquid on the substrate, or spins the substrate intermittently, or temporarily stops spinning of the substrate. Thus, treatment with the removal liquid progresses without a further supply of the removal liquid, thereby restraining consumption of the removal liquid.

Abstract: An indexer part, removal processing part, interface, and dry processing part are disposed adjacent to each other in a row. That is, the removal processing part that performs removal processing of an organic matter by using a removal liquid is disposed adjacent to the indexer part loading and unloading a substrate with respect to the exterior of an apparatus. The interface that gives and receives a substrate between the removal processing part and dry processing part is interposed between the removal processing part and the dry processing part that performs dry processing of a substrate after passing through the removal processing. This enables to provide a substrate processing apparatus that can completely dry the substrate after a reaction product removal processing.
