Abstract
Abstract A charge-coupled device (CCD) imager is comprised of a CCD image sensor (1), a horizontal register (2) for delivering an image signal from the CCD image sensor, the horizontal register being formed of an effective bit portion (2a) corresponding to the CCD image sensor (1) and first and second dummy bit portions (2b,2c) of a predeterminded length which are located at both sides of the effective bit portion (2a), and first and second output portions (3,6) provided in succession to the first and second dummy bit portions (2b,2c) to provide a positive image signal and a mirror image signal, wherein the effective bit portion (2a) is provided with four bus lines (4a₁,4a₂,5a₁,5a₂) through which a transfer clock is supplied to the horizontal register (2) and the first and second dummy bit portions (2b,2c) are provided with two bus lines (4a₂, 5a₂) through which a transfer clock is supplied to the horizontal register (2). Thus, the CCD imager can be simplified in arrangement and a undesirable charge can be prevented from being mixed into a signal charge.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
161 words
A charge-coupled device (CCD) imager comprising: a) a CCD image sensor (1); b) a horizontal register (2) for delivering an image signal from said CCD image sensor (1), said horizontal register being formed of an effective bit portion (2a) corresponding to said CCD image sensor and first and second dummy bit portions (2b,2c) of a predetermined length, said first and second dummy bit portions (2b ,2c) being located at both sides of said effective bit portion (2a); and first and second output portions (3,6) provided in succession to said first and second dummy bit portions (2b,2c) to provide a positive image signal and a minor image signal, wherein said effective bit portion (2a) is connected with four bus lines (4a₁,4a₂,5a₁,5a₂) through which a transfer clock is supplied to said horizontal register (2) and said first and second dummy bit portions (2b,2c) are each connected with two bus lines (4a₂,5a₂) through which a transfer clock is supplied to said horizontal register (2).
Claim 2
Dependent Claim
161 words
A charge-coupled device (CCD) imager comprising: a) a CCD image sensor (1); b) a horizontal register (2) for delivering an image signal from said CCD image sensor (1), said horizontal register being formed of an effective bit portion (2a) corresponding to said CCD image sensor and first and second dummy bit portions (2b,2c) of a predetermined length, said first and second dummy bit portions (2b ,2c) being located at both sides of said effective bit portion (2a); and first and second output portions (3,6) provided in succession to said first and second dummy bit portions (2b,2c) to provide a positive image signal and a minor image signal, wherein said effective bit portion (2a) is connected with four bus lines (4a₁,4a₂,5a₁,5a₂) through which a transfer clock is supplied to said horizontal register (2) and said first and second dummy bit portions (2b,2c) are each connected with two bus lines (4a₂,5a₂) through which a transfer clock is supplied to said horizontal register (2).
