Abstract
An image sending apparatus has a conversion member for converting a radiation wave into visual light, an image sensing area having a plurality of pixels for converting the visual light converted by the converting member into an electrical signal, and a shielding member mounted in a partial area of the image sensing apparatus for shielding the radiation wave.
Claims13
An image sensing apparatus comprising:
- a converting member that converts a radiation wave into visual light having a wavelength longer than that of the radiation wave;
- an image sensing unit having a plurality of photoelectric conversion portions for converting visual light converted by said converting member into an electric signal, said image sensing unit including an image sensing area and an optical black area, each of the image sensing area and the optical black area having a plurality of photoelectric conversion portions arranged such that there is space between photoelectric conversion portions;
- a scanning circuit that sequentially outputs signals from the photoelectric conversion portions, said scanning circuit being arranged on a same semiconductor substrate as said image sensing unit, at the periphery of said image sensing unit;
- and
- a common shielding member arranged to shield said scanning circuit and the optical black area of the image sensing unit.

An image sensing apparatus comprising:
- a converting member that converts a radiation wave into visual light having a wavelength longer than that of the radiation wave;
- an image sensing sensor having an image sensing area including a plurality of pixels each of which converts visual light, converted by said converting member, into an electrical signal;
- a mounting board on which said image sensing sensor is mounted;
- a driving circuit, arranged in a peripheral area of said image sensing sensor, that drives said image sensing sensor, wherein said image sensing sensor and said driving circuit are not arranged on a same semiconductor chip;
- a light guiding member that guides visual light onto said image sensing area, thereby reducing the radiation wave, wherein said light guiding member is arranged above said image sensing area but is not arranged above said driving circuit;
- a scanning circuit that sequentially outputs signals from the photoelectric conversion portions, said scanning circuit being arranged on a same semiconductor chip as said image sensing sensor, at the periphery of said image sensing sensor;
- and
- a common shielding member that shields against the radiation wave, wherein said common shielding member is arranged to shield said driving circuit and said scanning circuit.
