Abstract
Abstract In an X-ray fluoroscopic apparatus including an X-ray tube for radiating an X-ray onto an object to be examined, an image intensifier for converting an X-ray image transmitted through the object into an optical image, a solid-state imaging device having an amorphous silicon layered type charge-coupled device for imaging the optical image through an optical system connected to an output of the image intensifier, and a display for displaying an output image signal from the solid-state imaging device. The solid-state imaging device performs interlaced scanning in a frame storage mode in the odd-numbered field, and in a field storage mode in the even-numbered field.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
79 words
A solid-state imaging device for performing interlaced reading, comprising: light-receiving sections arranged in a two-dimensional matrix; a vertical transfer section adjacent to a light-receiving section in each line of the light-receiving sections; and means for reading signals in different modes during alternate fields of a frame period, including reading, in an odd-numbered field period, from said light-receiving sections in a frame storage mode, and, reading in an even-numbered field period from the light-receiving sections in a field storage mode.
Claim 2
Dependent Claim
79 words
A solid-state imaging device for performing interlaced reading, comprising: light-receiving sections arranged in a two-dimensional matrix; a vertical transfer section adjacent to a light-receiving section in each line of the light-receiving sections; and means for reading signals in different modes during alternate fields of a frame period, including reading, in an odd-numbered field period, from said light-receiving sections in a frame storage mode, and, reading in an even-numbered field period from the light-receiving sections in a field storage mode.
Claim 3
Dependent Claim
67 words
A device according to claim 1, in which said reading means comprises means for reading signals from every other light-receiving section in the vertical direction as a signal of one pixel in the odd-numbered field in the frame storage mode, and reading signals from adjacent two light-receiving sections in the vertical direction as a signal of one pixel in the even-numbered field in the field storage mode.
Claim 4
Dependent Claim
19 words
A device according to claim 1, in which said light-receiving sections comprise an amorphous silicon layered type charge-coupled devices.
Claim 5
Dependent Claim
58 words
A device according to claim 1, wherein said reading means comprises means for reading signals from light-receiving sections on odd-numbered scanning lines as odd-numbered scanning line signals in the odd-numbered field, and reading signals from light-receiving sections on pairs of the odd-numbered scanning lines and the even-numbered scanning lines as even-numbered scanning line signals in the even-numbered field.
Claim 6
Dependent Claim
14 words
A device according to claim 1, wherein said light-receiving section comprises a charge-coupled device.
