摘要： An image input device or a solid-state image sensing device using a CCD linear sensor includes a main sensor array and a sub sensor array. A transfer register for the sub sensor array is provided with charge sweep means for sweeping away unnecessary charges. Thus, only signals in the main sensor array are selectively read out without being affected by signals in the sub sensor array.

摘要： In a three-line linear sensor, a first linear sensor (10) without electronic shutter structure and second and third linear sensors (20), (30) with electronic shutter structures (28), (38) being disposed in an axial symmetry fashion are combined and a line spacing (D1) between the first and second linear sensors (10), (20) can be reduced by an amount corresponding to the omitted electronic shutter structure.

摘要： A CCD linear sensor as a solid-state imaging device has a photosensor and a pair of CCD registers connected to the photosensor. One of the CCD registers is supplied with first two-phase transfer clock signals for transferring electric charges from the photosensor to a first signal converter, and the other CCD register is supplied with second two-phase transfer clock signals for transferring electric charges from the photosensor to a second signal converter. The second two-phase transfer clock signals are shifted a 1/2 clock period from the first two-phase transfer clock signals. The CCD registers have the same number of dummy registers on their output ends for transferring the electric charges therethrough to the first and second signal converters, which convert the transferred electric charges into output signals that are in phase with each other. The periods of the output signals and the negative-going edges, i.e., the transitions, of reset pulses applied to the gates of FETS connected to the first and second signal converters are separate in time from each other, preventing coupling-induced noise from being included in the signal periods. The clock signals can thus be generated at a higher frequency and at a higher speed, making it possible to process the image signals at a higher frequency and at a higher speed.
