ABSTRACT:
A solid-state imaging device having weighted sensitivity distribution includes a pixel having a main area and at least one sub-area positioned adjacent the main area. Each of the main and sub-areas produces an output signal. A processing circuit is provided for receiving the output signals from the main and sub-areas, suppressing an intensity of the sub-area output signal, inverting a polarity of the sub-area output signal, and combining the suppressed and inverted sub-area output signal with the main area output signal to provide a pixel output signal having enhanced sensitivity.
