To provide estimating apparatus and method of the optical distortion of light transmitted through a transparent plate-shaped body. Upon picking-up a grid pattern via a glass plate by an image pickup device 4, 4n±α CCD pixels correspond to n grids (pair of a bright portion and a dark portion), thereby generating α moire fringes. Sine waves with a phase A and sine waves with a phase B deviated from the phase A by 90° are generated based on gray data of the picked-up image in this state. A phase angle at each pixel on the Lissajous figure is calculated based on the sine waves with the phases A and B, and the refractive power is calculated based on a phase angular speed, serving as the difference between the phase angles of the pixels.

An object of the present invention is to apply a phase shift method to a workpiece having a rough surface to accurately detect an abnormal concave-convex irregularity. Therefore, in an inspecting system of the present invention, an image of a stripe pattern reflected on an inspection target surface is detected at a shallow angle, and one or more continuous unit stripes of a unit stripes reflected image is specified among from the stripe pattern reflected images existing in a predetermined distance range counted from the edge in a closer side to the workpiece. Then, the phase of the specified unit stripes reflected image is varied to apply a phase shift method and scan the inspection target surface with the unit stripes reflected image to thereby detect the abnormal concave-convex irregularity.

A reference start point RPS and a reference end point RPE for detecting a beat position BP.sub.n are set as a BP.sub.n-1 +BT.+-.DR on the basis of a beat interval BT obtained by user's guide tapping for a predetermined time, a predetermined deviation value DR and the detected last beat position BP.sub.n-1. Thus, the crest value Lrp of an audio signal exceeding a predetermined threshold TH in the specified retrieval interval is obtained. Each beat position BP.sub.n is obtained on the basis of a reference point RS of the audio signal existing when the crest value is obtained. In reproduction of an audio signal by a DMTR, a MIDI clock is generated from the beat position and output to a MIDI sequencer, etc.

An inspection system is provided that can calculate highly accurate data for inspection having a high S/N ratio with high freedom. In order to attain this, an imaging timing is adjusted to synchronize a time for a projected image of an object to move by “m” pixels (“m” is an integer number greater than or equal to 1) in the X-axis direction on imaging elements, with an imaging time interval, and partial image data imaged at the identical inspection position on the object is specified from each unit of two-dimensional image data based on the object appearing deviated by “m” pixels in the X-axis direction in each unit of the two-dimensional image data imaged at each of the imaging timings, and data for inspection in which a noise reducing processing is conducted at the inspection position is produced based on each section of the partial image data.

There are provided a method and apparatus capable of conveniently and rapidly inspecting a warpage of a rod. A rod to be inspected is rolled down an inspection bed and light shielded by the downwardly rolling rod is detected by a line sensor as a one-dimensional image signal. A positional fluctuation value of the downwardly rolling rod is obtained from a two-dimensional image signal obtained from the one-dimensional image signal. Based on the positional fluctuation value, the degree of the warpage of the rod is determined. The shielded light signal is detected in the vicinity of one end of the downwardly rolling rod to be inspected.
