Time-of-flight image sensor resolution enchantment and increased data robustness using a binning module

A time-of-flight (ToF) image sensor system, comprising:

• an illumination source configured to generate a modulated light signal;
• a pixel array comprising a plurality of actual pixel lines and a plurality of actual pixel columns, wherein each pixel of the pixel array is configured to receive the modulated light signal reflected from an object as a reflected modulated light signal and to demodulate the reflected modulated light signal to generate an electrical signal;
• a plurality of analog-to-digital converters (ADCs), wherein each ADC is coupled to at least one assigned pixel of the pixel array and is configured to convert a corresponding electrical signal generated by the at least one assigned pixel into an actual pixel value;
• a binning circuit coupled to the plurality of ADCs and configured to generate at least one interpolated pixel, wherein the binning circuit is configured to generate each of the at least one interpolated pixel based on actual pixel values corresponding to a different pair of adjacent pixels of the pixel array, each of the at least one interpolated pixel having a virtual pixel value;
• and
• an output circuit coupled to the binning circuit and configured to output the virtual pixel value of each of the at least one interpolated pixel according to an image structure.
