Definition

(Für diese Definition ist die deutsche Übersetzung noch nicht abgeschlossen)

Definition

• Arrangement of scanning circuits for generating control signals for a multiplexer or an arrangement of switches that connects the column lines of the sensor array to the sensor output. In contrast to CCD sensors, addressed image sensors do not necessarily comprise transfer or readout registers that transfer the image signal to the output.

• Details of analogue (pixel signal) shift registers and scanning circuits thereof.
• Bucket-brigade type shift registers.
• Details of digital (signal) shift registers and scanning circuits thereof.
• Horizontal and vertical lines to read out the pixel array in x- and y- directions.
• Multiple horizontal readout lines for different sensor regions.
• Multiple horizontal readout lines for different colours.
• Details of multiplexer or switches for horizontal scanning used for performing horizontal binning between signals from different column lines.
• Details of multiplexer or switches for outputting signals from a column line to different readout line.

Circuits like AD converters, correlated double sampling or amplifiers provided for each column are not part of the readout registers, but all these circuits can be part of a readout circuit. Details of column parallel AD converters, CDS circuits or column amplifiers are classified in group H04N 25/78. Group H04N 25/767 covers details of how the data is transmitted to the output.
