Abstract:
1. A device for converting a digital pixel signal to an analog output signal having a target format, the device comprising: a pixel pipeline circuit configured to provide a pixel stream comprising digital pixel values, wherein the pixel pipeline circuit has an input connected with a digital pixel buffer; an encoder coupled to an output of the pixel pipeline circuit and having one or more processor elements configured to convert the pixel stream to digital sample values corresponding to a target analog signal representing the pixel stream in the target format, thereby generating a base data stream at a base sampling rate corresponding to the target format; a supersampling circuit coupled to an output of the encoder and configured to generate a supersampled data stream at a supersampling rate from the base data stream, the supersampling rate being higher than the base sampling rate; and a digital to analog converter coupled to an output of the supersampling circuit and configured to convert the supersampled data stream to the analog output signal having the target format with the base sampling rate.
