Abstract:
An apparatus comprising:a plurality of pixel sensors, each pixel sensor having a first input, a second input and an output, wherein said plurality of pixel sensors are divided into columns, each first input of said pixel sensors within each of said columns being coupled in series, and each column being coupled alternatively to receive first and second signals respectively,said pixel sensors further divided into rows, each second input of said pixel sensors within each of said rows being coupled in series, and each row being coupled alternatively to receive a third signal and a fourth signal respectively;said first inputs of said pixel sensors coupled alternatively to receive a first signal and a second signal respectively; andsaid outputs of said pixel sensors generating output signals corresponding to said first and second signals received at said first inputs;a generator coupled to said first and second inputs of said pixel sensors to generate said first, second, third and fourth signals, wherein said generator further comprises a first, second, third and fourth multiplexor, said first multiplexor coupled to said first inputs for receiving said first signal, said second multiplexor coupled to said first inputs for receiving said second signal, said third multiplexor coupled to said second inputs for receiving said third signal and said fourth multiplexor coupled to said second inputs for receiving said fourth signal, said first, second, third and fourth multiplexors selecting said first, second, third and fourth signals from a plurality of signals generated by said generator; and a display arrangement.
