Filed: 1987-02-20
Abstract: PURPOSE:To prolong the life of a lamp by detecting the best value of a turn-on pulse and preventing the lamp from being turned on with a pulse having unnecessarily large time width. CONSTITUTION:The turn-on pulse width of the hollow cathode lamp 1 is found prior to actual measurement. Namely, sampling circuits 6 and 6' sample an absorbance signal at time intervals shorter than the time width of the turn-on pulse from the beginning of illumination during the illumination period based upon a large current pulse. Then ratios of or differences between an absorbance signal by 1st sampling and respective absorbance signals by successive sampling are calculated through logarithmic converting circuits 7 and 7' and a subtracting circuit 8, and the time from the start point of the turn-on pulse where the values of two successive ratios or differences become smaller than a predetermined constant value is stored in a memory 10. Then when a measurement is taken actually, the turn-on pulse width of the hollow cathode lamp 1 is set to the time stored in the memory 10 to prolong the life of the lamp without turning on the lamp 1 with a large current having an unnecessarily long time width.

Abstract: PURPOSE: To eliminate the malfunction and wrong detection of autofocusing by calculating a noise offset level, subtracting it from an evaluated value, and setting the position of a focus lens so that the value calculated by the subtraction can be a peak. CONSTITUTION: A noise offset level calculating part 12c calculates the noise offset level corresponding to any specified AGC level and photometric value based on data in a data and table preparing/storage part 12b and outputs this level to subtracters 12d and 12e. The subtracter 12d subtracts a noise offset level N from the first evaluated value and applies the result to a focus control part 12a as the new first evaluated value. The subtraction part 12e subtracts the level N from the second evaluated value and applies the result to the control part 12a as the new second evaluated value. The control part 12a detects a moving direction while moving the focus lens by using the first evaluated value. Afterwards, the focus lens is stopped at the position, where the second evaluated value becomes the peak, by using this evaluated value.
