Abstract
There is a need to provide a solid-state imaging apparatus capable of highly accurately analog-to-digital converting an analog voltage output from a pixel circuit. The solid-state imaging apparatus supplies a counter code to an integral A/D converter. The counter code CD includes 3-phase clock signals and gray signals. The clock signals each have a cycle equal to specified cycle multiplied by 8 and allow phases to shift from each other by specified cycle. The gray signals linearly increase count values at a cycle equal to specified cycle multiplied by 4. The counter code reverses only the logical level of a signal when a count value changes. A count value error can be limited to a minimum.
