摘要:
Provided are an imaging module for an endoscope that favorably blocks incidence of flare light to an imaging element and an electronic endoscope device including the same. The imaging module for an endoscope includes an objective lens optical system; a transparent optical member 56; an imaging element 58 that is of a microlens non-mounting type; an adhesive layer; and a light shielding mask 121 for a measure against flare that is interposed between a light emission surface 56a and a light incidence surface, is formed with an opening 121a, which matches an image circle that passes through the objective lens optical system and the transparent optical member 56 and is formed on the light incidence surface of the imaging element 58 and has a smaller diameter than the image circle, and is provided immediately before the light incidence surface of the imaging element 58.

Disclosed are an image defect detection device, method and an imaging unit capable of reliably detecting image defect, such as stripe unevenness or scratches, even if a comparatively inexpensive and low resolution imaging unit is used. An image reading unit has a plurality of read pixels arranged in a second direction intersecting a first direction and reads an image recorded on a recording medium by a single-pass recording head, which is relatively moved in the first direction. A birefringent plate shifts and duplexes the image at least in the second direction by performing birefringence of image light of the image. The birefringent plate makes the width of image defect in the second direction on the read pixels greater than the pitch of the read pixels. A detection unit which detects image defect included in the image and extended in the first direction based on the reading result of the image.
