ABSTRACT:
Row driving circuits drive a plurality of kinds of pixels in each scanning line. Column reading circuits read from the plurality of kinds of pixels in each column. A column selection circuit for GR colors selects outputs of the column reading circuits in even numbered columns, and a column selection circuit for GB colors selects outputs of the column reading circuits in odd numbered columns. In this way, in a predetermined line, only G signals are output from the column selection circuit for GR colors, and only B signals are output from the column selection circuit for GB colors. Similarly, in the next line, only R signals and only G signals are output from the selection circuits. By amplifying outputs of the column selection circuits with independent amplifications, pixel color based amplifications are possible. Amplifications can be changed in each line, and therefore the resolutions can be improved and outputs with good S/N ratio can be obtained with low speed devices.
