    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: There is provided an image processing device that includes a facial image extraction portion, a positivity computation portion, and a selected image update portion. The facial image extraction portion specifies a facial region of an imaged subject within at least one sequentially input selection-eligible image and extracts from the selection-eligible image a facial image that corresponds to the facial region. The positivity computation portion computes for the selection-eligible image, using the corresponding facial image, a positivity of the imaged subject toward a person who acquired the selection-eligible image. The selected image update portion compares the selection-eligible image for which the positivity was computed in the positivity computation portion to a selection candidate image that has the greatest positivity among selection-eligible images for the same imaged subject for which the positivities have already been computed, and makes the image with the greater positivity the new selection candidate image.
