A wiring board includes a wiring forming region in which a plurality of wiring layers are stacked while sandwiching insulating layers, an outer periphery region which is arranged around the wiring forming region and in which a reinforcing pattern is formed in the same layer as each of the wiring layers. An area ratio of the reinforcing pattern to the outer periphery region and an area ratio of the wiring layer to the wiring forming region are substantially the same in each of the layers, and the reinforcing patterns exist without a gap in the outer periphery region when the wiring board is viewed in planar perspective.

摘要:
An imaging device with a semi-column-parallel pipeline analog-to-digital converter architecture. The semi-column-parallel pipeline architecture allows multiple column output lines to share an analog-to-digital converter. Analog-to-digital conversions are performed in a pipelined manner to reduce the conversion time, which results in shorter row times and increased frames rate and data throughput. The architecture also enhances the pitch of the analog-to-digital converters, which allows high performance, high resolution analog-to-digital converters to be used. As such, semi-column-parallel pipeline architecture overcomes the shortcomings of the typical serial and column-parallel architectures.
