Abstract

A pixel array for use in a high dynamic range image sensor includes a plurality of pixels arranged in a plurality of rows and columns in the pixel array. Each one of the pixels includes a linear subpixel and a log subpixel disposed in a semiconductor material. The linear subpixel is coupled to generate a linear output signal having a linear response, and the log subpixel is coupled to generate a log output signal having a logarithmic response in response to the incident light. A bitline is coupled to the linear subpixel and to the log subpixel to receive the linear output signal and the log output signal. The bitline is one of a plurality of bitlines coupled to the plurality of pixels. Each one of the plurality of bitlines is coupled to a corresponding grouping of the plurality of pixels.
