Patent ID: 6961457

Claim:
A bonding apparatus comprised of a processing member that processing bonding parts, a first imaging device of high magnification that images a specific pattern, and a first offset calculating means that calculates an amount of offset between said processing member and said first imaging device based upon image data acquired by said first imaging device, said bonding apparatus further comprising: a second imaging device that images said specific pattern, said second imaging device having low magnification that is lower than said first imaging device, and a second offset calculating means that calculates an amount of deviation between a reference point of a first image data acquired by said first imaging device and a reference point of second image data acquired by said second imaging device based upon said first image data and said second image data and wherein said second offset calculating means calculates said offset by: performing reduction processing so that the image data with higher magnification obtained by said first imaging device and image data obtained by said second imaging device are caused to match an imaging magnification on a lower magnification side, and comparing an image obtained by said reduction processing with said image data on said lower magnification aside.
