Document Type and Number:
WIPO Patent Application WO/2011/102281
Kind Code:
A1
Abstract:
Disclosed are an image signal processing circuit, an image capture device, an image signal processing method, and a program, which are capable of extracting, with a high degree of precision, particular information, including bar codes, with regular lenses, without requiring specialized EDOF lenses or signal processing circuits. An image signal processing circuit comprises a processing circuit (131) that carries out image processing with one color signal (B), from among a plurality of color signals, that possesses a resolution on the near point side; and an enhancement processing unit (132) that carries out enhancement processing, applying an inverse function of a point spread function (PSF) upon a signal that is image processed with one color signal by the processing circuit.
