SOLID STATE IMAGE PICKING-UP DEVICE AND IMAGE PICKING-UP SIGNAL OUTPUT CIRCUIT

摘要

A pixel signal obtained by imaging with a solid-state image sensor element can be output selectably either in n bits or in a bit number of an integral multiple of n in synchronization with an output clock. A clock converting unit (26), an allocating unit (32), a first selector (31), a second selector (27), and an output mode control unit are provided for the purpose. The allocating unit (32) allocates respective bit data of pixel signal obtained by imaging with the solid-state image sensor element into at least two series of bit data alternately, in synchronization with clock converted by the clock converting unit (26). The first selector (31) selects an output from the bit data allocated by the allocating unit (32) and the bit data not allocated by the allocating unit (32). The second selector (27) selects an output from a clock with a frequency converted by the clock converting unit (26) and a clock with a frequency not converted by the clock converting unit (26).
