    摘要: A correlator, such as may be used in a phase detecting device of an automatic focusing circuit for a camera , has a simple arrangement that attains improved accuracy and high speed. A pair of charge storing elements is provided to which input signals are applied. When predetermined charges are supplied into potential wells formed in the charge storing elements, charge remaining in the potential wells depending on their depth can be detected as the absolute value of the difference between the two input signals. Therefore, the input signals can be subjected to correlation directly as they are, that is, in analog form, without conversion to digital form.

    摘要: A phase difference-detecting apparatus for detecting a relative distance between a pair of focused images obtained from subject luminous flux passed through an objective lens to thereby judge a focusing state of the objective lens. The apparatus includes a pair of signal generating sections which receive the subject flux and provide first and second time series signals. A switching-capacitor integrator is provided including a plurality of capacitive elements and switching elements for intermittently connecting the capacitive elements to each other, and for receiving the first and second time series signals. A control device compares the sizes of the first and second time series signals with each other to thereby generate a control signal corresponding to a relation of size between the first and second time series signals. The switching elements are controlled on the basis of the control signal to cause the switching-capacitor integrated value of an absolute value of a difference between the first and second time series signals, and to cause the switching-capacitor integrator to generate, as a correlation value, an integrated value on the basis of the first and second time series signals in predetermined numbers whenever the quantity of relative movement is changed.

    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.
