Abstract: An image data circuit compensates sensitivity differences in image detection between a pair of image sensors. The image sensors each include a plurality of charge storage type optical sensing elements. Correction data indicative of sensitivity difference between the image sensors is stored in permanent memory. A clock pulse generator circuit generates clock pulses for counting charge storage periods indicated by output signals from the optical sensing elements. A pair of counter circuits counts the clock pulses and outputs count values corrected with the correction data and corresponding to the charge storage periods. A pair of quantizing circuits converts the output signals to image data based on the corrected count values.

Abstract: A method of detecting a phase difference between a pair of images of an object which are formed on a pair of optical sensor arrays through different optical paths, with presence of flare in one of the images, is disclosed. The method includes the steps of: preparing a sensor data group representing a pattern of each image and consisting of sensor data received from each optical sensor array; correcting the sensor data group so as to eliminate a difference in the average value of the sensor data between the optical sensor arrays; preparing a plurality of combinations each having two subgroups corresponding to the pair of optical sensor arrays, each subgroup consisting of a predetermined number of a series of sensor data, which are selected from the sensor data group corrected, such that a portion of the sensor data group from which the subgroup is selected is sequentially shifted; and selecting one of the combinations having a maximum degree of correlation between the subgroups, and detecting a phase difference from positions on the optical sensor arrays which correspond to the subgroups of the selected combination.

Abstract: For correction of an error caused in a period of a clock signal for digitizing a plurality of time signals, e.g., from an image sensor, a clock signal generating device generates a reference signal Sr indicative of a reference time of time signals TS from an OR-date (20). The device counts a reference clock signal .phi. in a frequency divider (30) until the reference signal Sr is generated, and outputs a divided clock signal .phi..sub.n with frequency dividing ratio 1/N from the frequency divider (30). It then counts the signal .phi..sub.n and stores the count value as a reference value S in a reference value counter (40). The device outputs an output clock signal .phi..sub.o from an output counter (50) each time the signal .phi. received after generation of the signal Sr reaches a predetermined value. It accumulates in an accumulator (60) the count value of the frequency divider (30) at the time of generation of the signal Sr in response to the signal .phi..sub.o, and it sets a reference value of the counter (50) for counting the signal .phi., to generate the signal .phi..sub.o usually at S, and at 1+S when an accumulated value in the accumulator (60) reaches the parameter N of the frequency dividing ratio.

Abstract: In a focus detection system in which light from an object is incident on at least two photosensor arrays via an optical system to form two images on the photosensor arrays, the relative displacement between the two images is determined in order to detect whether the optical system is in focus or not. A correction term which is formed by f(i.sub.0 +2) and f(i.sub.0 +1) or f(i.sub.0 -2) and f(i.sub.0 -1) is added to f(i.sub.0-1)-f(i.sub.0) or f(i.sub.0 +1)-f(i.sub.0), so that the amount of image deviation between the two images is obtained. Here i.sub.0 is the value of i when a function f(i) is minimized, the function f(i) expressing the inconsistency between the two images, corresponding to an amount of relative displacement i.times.p between the two images obtained discretely. The symbol p represents the pitch of the at least two photosensor arrays.

Abstract: An acceleration measuring device consists of a sealed-off, diode vacuum tube which in turn contains a cold cathode and an anode positioned at opposing longitudinal end regions of the vacuum tube via an inter-electrode space C. An inert argon gas is sealed in the vacuum tube at the pressure of 1 mm Hg. Because the acceleration measuring device utilizes field effect electron emission phenomenon, i.e., quantum mechanical tunneling by the Schottky effect, from the cold cathode, one obtains electron-emission characteristics which are essentially temperature independent. The vacuum tube also includes one or more areas connected to the inter-electrode space, local density of the gas in which connected areas changes in response to acceleration experienced by the acceleration measuring device, whereby the density of the gas in the inter-electrode space is altered. Since the density of the gas in the inter-electrode space between the mutually opposing electrodes corresponds essentially linearly to the impedance against the electron flow towards the anode, the anode current is inversely proportional to the density of the gas in the inter-electrode space. The magnitude of the acceleration is measured by detecting the variation of the anode current.
