Abstract: A fast imaging device 32 has a charge signal converter 33, a charge signal accumulator 36 and a charge signal transporter 37. A charge signal accumulator 36 is provided to each charge signal converter 33. A charge signal accumulator 36 extends linearly while inclining with respect to a line L2 connecting charge signal converter 33. The other end of a charge signal accumulator 36, connected at one end thereof to a charge signal converter 33 constituting a corresponding column, merges to a charge signal transporter 37. This construction reduces noise and increases a frame rate.

Abstract: A high-speed image sensor has a plurality of signal converting means (30) for generating electric signals corresponding to an incident light intensity and a plurality of electric signal recording means (33) for recording electric signals output from corresponding signal converting means (30). The electric signal recording means (33) is linearly shaped and has a read-out line (58a) for each of longitudinal sections thereof. The read-out line (58) is used for directly reading out the electric signals out of a light receptive area.
