An operation switch includes: a capacitance sensor that generates three or more detection signals in response to approach or contact of an object to respective three or more electrodes; a determination circuit that determines whether or not the object is a living body based on one or more detection signals selected from the three or more detection signals, the one or more detection signals excluding a detection signal having a maximum intensity among the three or more detection signals; and a controller that, when the object is determined to be a living body, generates an operation signal for operating a predetermined device.

A control switch for controlling a level of an operation of an apparatus among operating levels including first, second, and third operating levels includes: sensors each of which, in operation, senses an object, the sensors including first, second, and third sensors arranged along one direction, the first, second, and third sensors being assigned first, second, and third level values, respectively; an acquisition circuit that, in operation, acquires a moving velocity of the object along the direction with the first, second, and third sensors; a change circuit that, in operation, changes at least two of the first, second, and third level values according to the moving velocity; and a control circuit that, in operation, causes the apparatus to operate at an operating level corresponding to the level value assigned to one of the first, second, and third sensors which has sensed the object.

The error correction processing includes: data reproduction processing of reproducing recording data, constituted by a plurality of data units each made of a plurality of bits, from a recording medium sequentially; error correction processing of performing error correction in the row direction and error correction in the column direction at least once for an error correction code block that has the reproduced recording data arranged in the row direction over a plurality of rows; determination processing of determining whether uncorrectable data is left behind after execution of the error correction processing; and erasure correction processing of performing, when it is determined that uncorrectable data is left behind, column-direction error correction considering data constituting at least one row of the error correction code block as erasure data, even in cases where uncorrectable data in the error correction in the row direction is not left behind.
