A digital image acquisition system having no photographic film, such as a digital camera, has a flash unit for providing illumination during image capture and a red-eye filter for detecting a region within a captured image indicative of a red-eye phenomenon, the detection being based upon a comparison of the captured image and a reference image of nominally the same scene taken without flash. The bonded composite has first and second thin-section elements bonded to each other, at least in part by bond elements and at least in part by adherent material. According to the invention, the solvent used in developing printing plates can be reclaimed andor recycled by simply centrifuging the polymer-contaminated solvent. This configuration, underwater will naturally orient the apparatus in the upright vertical position with the float end and fish hook on top and the weighted end resting on bottom, while positioning the baited hook outward and away from shaft in view of foraging fish. In addition, since the components are integrated with the wiring board and embedded, the strength thereof can be enhanced. A maximum value of the second DC offset value is set larger than a multiplication value of a gain of the amplifier by a minimum resolution value of the first DC offset value.
