摘要： An output current of a photodiode is charged in a capacitor, and the voltage change of the capacitor is monitored by a plurality of comparators. The time required for the capacitor voltage to reach a predetermined value is counted by using a clock signal input unit for inputting a clock signal of a predetermined frequency, and a counter for counting an upper part of a number corresponding to a logarithm of a number of clocks of the clock signal generated after the integration start by a photoelectric conversion unit. The outputs of the comparators when the counter counts the upper part are latched, and the lower part of the number is supplied.

摘要： A pair of optical systems of the same characteristics are disposed spaced apart by a base line length in the direction perpendicular to an optical axis, to form a focal plane, on which a standard photosensor and a reference photosensor, each having a plurality of photosensor elements, are disposed. An image of an object is focused onto the standard and reference photosensors, to generate a standard optical signal and a reference optical signal which are compared with each other, while changing the phase of the reference optical signal relative to the phase of the standard optical signal to calculate correlation factors. A distance to the object is detected from a phase having an extreme value of the calculated correlation factors. If the calculated correlation factors are asymmetrical relative to the extreme value, one correlation factor change by a unit phase shift before the extreme value is subtracted from the other correlation factor change by the unit phase shift after the extreme value. The subtraction result is divided by a constant. The division result is added to the correlation factors at sampling points adjacent the extreme value on the side of the other correlation factor change. The addition results are used as the corrected correlation factors, to perform an interpolation calculation to obtain a phase having an extreme value of the corrected correlation factors.

摘要： A transistor includes p-type semiconductor (12) including a projection (13a) having a pair of side walls (13b, 13b) facing each other, a gate insulation layer (15c), a pair of n-type source/drain regions (BL1, BL2), tunnel insulation layers (15a), a pair of floating gates (FG1, FG2), inter-polycrystalline insulation layers, and a control gate (CG). The root portion of the projection (13A), which virtually connects the source/drain regions (BL1, BL2) with a straight line, is higher in the concentration of the p-type impurity than the other portion. A delete voltage for deleting charges stored in the floating gate (FG) is applied between the control gate (CG) and the source/drain region (BL1, BL2), so that a delete current flows toward the control gate (CG) or the source/drain region (BL1, BL2), the charges stored being deleted.

摘要： A phase difference detection unit for an automatic focusing system of a camera or the like. The phase difference detecting unit includes a pair of linear image pickup devices which receive a pair of optical images of an object formed by the lens in the automatic focusing system of a camera or the like. The detecting unit also has a correlation operating circuit which determines whether or not the lens of the focusing system is in a proper focus condition. The proper focus condition is determined by a minimum correlation value output by the correlation operating circuit, the value being indicative of the correlation between a pair of phase shifted analog electrical signals representative of the optical images received by the pickup devices. The correlation operating circuit is capable of operation at high speed with improved accuracy by maintaining the capacitive loads of the input terminals of the correlation operating circuit.
