Abstract: PURPOSE:To jumpedly enhance the resolving power for detecting a distance even in a frequency range of a clock pulse capable of being respondent to a general purpose digital IC by providing a processing means for calculating distances by performing calculation and processing on the basis of a reflected pulse beam waveform that has been obtained by rearranging in time series and synthesizing N sets of reflected pulse beam sample waveforms stored in a storing means. CONSTITUTION:A pulse beam is emitted onto an object 10 in a timing synchronized with a delay clock pulse. The reflected pulse beam thereof is subjected to A/D conversion and are successively stored in a memory 5. This operation is carried out by changing the delay time every time plural times of pulses are emitted. Then, the A/D conversion values of plural times of reflected pulse beam signals which have been stored in a processing unit 7 are successively read out, and the read data are rearranged while considering time series for synthesizing one waveform, and from the data position giving the maximum value of the signals, the distance up to the object is measured by calculation. Thus, even if a general purpose digital I/D or the like is used, high resolving- power and high accuracy distance measuring can be enabled.

Abstract: PURPOSE:To improve exposure accuracy and to photograph a still picture not to accompany a smear phenomenon, etc., by executing exposure for photometry by an electronic shutter, and executing main exposure by a mechanical shutter opening and closing member. CONSTITUTION:When the release of a camera is pushed by an operator, external photometry is executed by a photometry element and in exposure 1 for the photometry, the size of diaphragm and a shutter speed are determined.
