System and method for high dynamic range image sensor sensitive array

摘要

A method is disclosed of a heterogeneous image sensor array comprising more than one image sensor structures that are interconnected. The final image sensor array image output for each image sensor structure or pixel is computed using single image sensor structure output data or output data from more than one image sensor structures. The heterogeneous array exhibits complexity, cost, power consumption, device yields and reliability benefits when compared to other image sensor array structures.

1. An image sensor array comprising multiple individual image sensors each sensitive to electromagnetic radiation used to sense electromagnetic radiation from an external scene and from this sensing create the electronic representation of the external scene during an image capture process, wherein the image sensor array comprises a plurality of communicating image sensors of different complexities in terms of number of circuit elements associated with dynamic range and wherein the plurality of image sensors are organized into image sensor sub-arrays, at least one of which comprises a first image sensor which prompts reset of output state of a second image sensor.
