ABSTRACT:
A driving method for a solid-state image sensing device includes the steps of: transferring signal charges generated at pixels (12) arranged in odd rows in the column upward direction through vertical transfer paths (13) each arranged for each column; temporarily accumulating the upward transferred signal charges for one field at a first accumulation region (14) and transferring the accumulated signal charges row by row in sequence for each field period through other vertical transfer paths (18) to a first horizontal path (16); transferring the upward transferred signal charges in the horizontal row direction row by row through the first horizontal transfer path (16); transferring signal charges generated at pixels (12) arranged in even rows in the column downward direction through the same vertical transfer paths (13); temporarily accumulating the downward transferred signal charges for one field at a second accumulation region (15) and transferring the accumulated signal charges row by row in sequence for each field period through other vertical transfer paths (19) to a second horizontal path (17); and transferring the downward transferred signal charges in the horizontal row direction row by row through the second horizontal transfer path (17) at a timing different (e.g., one cycle later) from that of the signal charge transfer through the first horizontal transfer path (16). The driving method enables both the interlaces and non-interlaced scanning without use of any external memory.
