摘要： A distance measuring apparatus has: an AF optical system for dividing object light beams into a pair thereof and forming images and; an AFIC for photoelectrically converting received object optical images in pixels, accumulating charges, and outputting object distance information on the basis of the object image signal. A CPU discriminates whether or not the object is based on a night view or a view in which the night view is the background on the basis of the output of the AFIC or an operation of a night view photographing mode switch, and corrects the object distance to a second predetermined distance shorter than a first predetermined distance when the object is based on the night view or the like and the object distance is longer than the first predetermined distance.

摘要： The present invention comprises a first distance-measuring mode in which a subject distance is measured on the basis of a subject image signal produced by at least a pair of integration-type light-receiving elements receiving the light from subjects, and a second distance-measuring mode in which the subject distance is measured on the basis of the image signal a steady-light removing section has produced by removing the steady-light component from the subject image signal. In measuring the distance, the second distance-measuring mode is forced to be on for a specific time. On the basis of the resulting image signal, the main subject is estimated and a light-receiving sensor sensing area is selected. The light-receiving sensor sensing area is used for integration control in continuing to obtain the subject image signal.

摘要： A ranging apparatus according to the present invention can execute accurate focusing even when photography is performed in, for example, an environment in which the background of a main subject to be photographed is a night view. This accurate focusing is executed by performing two pre-integration operations, one with light projection and the other without light projection, then comparing signal patterns obtained by the two pre-integration operations to thereby select a partial area of a line sensor, which shows a difference between the signal patterns obtained by the comparison, and mainly using an output from this area as a signal for ranging. Further, this ranging apparatus performs pre-emission before the ranging operation, using the line sensor to set the ranging area of the apparatus substantially equal to an image area to be shot, thereby determining the position of the main subject in the image area to be shot. Thus, the ranging apparatus can select a desired subject without focus lock operations.

摘要： A knock detection device for an internal combustion engine make provisions to prevent erroneous decisions from being made due to a steplike signal change at the time of mask removal or to an overlap between an LC resonance generation period and a knock occurrence period in high engine rpm conditions. A low-frequency component is removed from an ion current signal by an HPF, and the resulting flat signal is supplied to a mask circuit, thereby reducing the amount of discontinuity occurring at the time of mask removal and suppressing noise in an output signal of a BPF to a level that does not affect knock detection. Further, by setting the gate period in a peak-hold circuit slightly delayed with respect to the mask removal timing, noise associated with the mask removal is completely eliminated. As mask signals used to specify the mask period, in addition to a mask signal for removing the mask when a predetermined crankshaft angle is reached, a second signal is provided for removing the mask when a prescribed time required for LC resonance noise to settle down has elapsed from the end of spark discharge, and the mask is removed only when both of the mask signals are deactivated.
