Motion detection solid-state imaging device
First Claim
1. A motion detection solid-state imaging device comprising a plurality of photoelectric converters arranged in a matrix to form a receiving field, the device detecting motion of an image based on signals from the photoelectric converters wherein:
- first and second photoelectrics of the plurality of photoelectric converters which are spatially adjacent to each other are treated as a set;
a first light integration period of the first photoelectric converter is shorter than a second light integration period of the second photoelectric converter, while the first and second light integration periods end substantially at a same point of time;
the signals from the first and second photoelectric converters are both read out after the first and second light integration periods; and
a product of a ratio of the second light integration period with respect to the first light integration period and the signal from the first photoelectric converter is obtained so as to detect motion of the image based on a difference between the product and a signal from the second photoelectric converter.

Abstract
A motion detection solid-state imaging device of the present invention includes a plurality of photoelectric converters arranged in a matrix to form a receiving field, the device detecting motion of an image based on signals from the photoelectric converters. First and second photoelectrics of the plurality of photoelectric converters which are spatially adjacent to each other are treated as a set. A first light integration period of the first photoelectric converter is shorter than a second light integration period of the second photoelectric converter, while the first and second light integration periods end substantially at a same point of time. The signals from the first and second photoelectric converters are both read out after the first and second light integration periods. A product of a ratio of the second light integration period with respect to the first light integration period and the signal from the first photoelectric converter is obtained so as to detect motion of the image based on a difference between the product and a signal from the second photoelectric converter.

12. A motion detection solid-state imaging device, comprising:
- a plurality of photoelectric converters arranged in a matrix to form a receiving field; and
vertical CCDs provided along each column of the matrix arrangement, signal charges of the photoelectric converters in the column being transmitted and taken out through the vertical CCD of the column by resetting the photoelectric converters arranged in columns, wherein;a first photoelectric converter and a second photoelectric converter are alternately arranged for each column of the matrix arrangement so as to form the column; the first photoelectric converter is reset during a second light integration period of the second photoelectric converter so as to initiate a first light integration period of the first photoelectric converter, with the second light integration period of the second photoelectric converter being continued, and the first and second photoelectric converters are both reset at the end of the first and second light integration periods so as to take out the signal charges of the first and second photoelectric converters through the vertical CCD; and a product of a ratio of the second light integration period with respect to the first light integration period and a signal charge of the first photoelectric converter is obtained so as to detect motion of the image based on a difference between the product and a signal charge from the second photoelectric converter. - View Dependent Claims (13, 14, 15, 16)
