Abstract: An RGB video signal is generated by illuminating an object with light from a first monitor and capturing an image of the object with a camera. The second monitor holds a profile representing the correspondence relationship between R, G, and B values generated by displaying an image including values of R, G, and B on a reference monitor and capturing an image of the displayed image with the camera and X, Y, and Z values which are measurements of tristimulus values of the displayed image in the XYZ color space.

Abstract: A method of analyzing factor responsible errors in a wafer pattern which enables detection of an error ascribable to a difference between mask patterns and an error ascribable to another reason while distinguishing between the errors. A mask pattern is formed by etching a first mask at a first position within an etching chamber. Another mask pattern is formed by etching a second mask at a second position within the etching chamber. A wafer pattern is formed by single shot of exposing radiation through use of the first mask, and another wafer pattern is formed by single shot of exposing radiation through use of the second mask. The size of the wafer pattern formed through use of the first mask and the size of the wafer pattern formed through use of the second mask are compared with each other, thereby detecting a dimensional difference ascribable to a difference between mask patterns and a dimensional difference ascribable to another reason while distinguishing between the dimensional differences.

Abstract: A switching regulator is disclosed which is designed so that a negative feedback is applied to the base of a transistor constituting an oscillator adapted for chopping a DC voltage, only during a period of time which is required to effect pulse width control when the transistor is switched from conduction to non-conduction. A control circuit may also be provided which is arranged to compare the output of a current detecting circuit for detecting a current proportional to a current for driving a transformer with the output of an error voltage amplifier for amplifying an output resulting from comparison of a rectified version of the AC output of the transformer with a reference voltage. The foregoing control circuit is also arranged so that when the output of the current detecting circuit exceeds the output of the error amplifier, a trigger signal is imparted to cause the oscillator to be changed from the on state to the off state.
