Image pickup apparatus, radiation image pickup apparatus and radiation image pickup system
View Patent ↗An image pickup apparatus includes plural light receiving areas arranged two-dimensionally and a vertical scanning circuit composed of plural unit circuit stages arranged in the vertical direction and a horizontal scanning circuit composed of plural unit circuit stages arranged in the horizontal direction for selecting and reading the plural light receiving areas in succession and in which the vertical scanning circuit and the horizontal scanning circuit are arranged in spaces between the light receiving areas. A crossing area of the vertical scanning circuit and the horizontal scanning circuit, in a space between the light receiving areas, is divided into two areas, and at least a unit circuit of the horizontal scanning circuit is provided in one of the two areas while at least a unit circuit of the vertical scanning circuit is provided in the other of the two areas.
1. An image pickup apparatus which is provided with plural light receiving areas arranged two-dimensionally, and a vertical scanning circuit composed of plural unit circuit stages arranged in the vertical direction and a horizontal scanning circuit composed of plural unit circuit stages arranged in the horizontal direction, for selecting and reading said plural light receiving areas in succession and in which said vertical scanning circuit and said horizontal scanning circuit are arranged in spaces between said light receiving areas, wherein a crossing area of said vertical scanning circuit and said horizontal scanning circuit, in a space between said light receiving areas, is divided into two areas, and at least a unit circuit of said horizontal scanning circuit is provided in one of said two areas while at least a unit circuit of said vertical scanning circuit is provided in the other of said two areas.
2. An image pickup apparatus according to claim 1 , wherein two unit circuits of said horizontal scanning circuit are provided in said one of said two areas in which said horizontal scanning circuit is provided, or two unit circuits of said vertical scanning circuit are provided in said other of said two areas in which said vertical scanning circuit is provided.
3. An image pickup apparatus according to claim 1 , wherein different wiring layers are used for the vertical scanning circuit of said plural stages and the horizontal scanning circuit of said plural stage, and the length of wiring in each wiring layer remains unchanged in a crossing area of the vertical scanning circuit of said plural stages and the horizontal scanning circuit of said plural stages.
4. A radiation image pickup apparatus comprising an image pickup apparatus according to claim 1 , a scintillator plate, and a fiber optics plate.
5. A radiation image pickup system comprising:
a radiation image pickup apparatus comprising an image pickup apparatus according to claim 1 , a scintillator plate, and a fiber optics plate,
signal processing means for processing a signal from said radiation image pickup apparatus;
recording means for recording a signal from said signal processing means;
display means for displaying the signal from said signal processing means;
transmission process means for transmitting the signal from said signal processing means; and
a radiation source for generating said radiation.
