A method for restoring still image data acquired by capturing a subject image with an imaging element, includes: acquiring blur information regarding blur in a Y direction of the imaging element upon image capturing; sets a recovery matrix for recovering, from the still image data, image data to be acquired upon capturing the subject image in a state where there is no blur; recovers the image data by multiplying the recovery matrix and the still image data; computes plural types of noises which derive from the recovery matrix and which are periodically superimposed on the recovered image data in the Y direction, based on (i) noise period information regarding a noise superimposition period of each noise, (ii) the recovered image data, and (iii) the still image data; and eliminates the computed noise from the recovered image data.

A deciding apparatus and method for deciding an audio signal coding system. A digital signal processor receives a coded audio signal, selects a specific coding system for the coded audio signal based on a predetermined portion of a data sequence of additional data of the audio signal, and decodes the audio signal using the selected coding system. A memory stores decoded programs for decoding the coded audio signal.

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.

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.
