Image signal processing device performing image signal processing through plural channels

An image signal processing device comprising:

• a channel converter configured to:
• divide a first input signal stream by processing units and generate a first plurality of processing unit signals, the first input signal stream comprising first image signals generated by a first plurality of pixels of an image sensor, and
• divide a second input signal stream by the processing units and generate a second plurality of processing unit signals, the second input signal stream comprising second image signals generated by a second plurality of pixels of the image sensor;
• an image signal processing core comprising a plurality of image processing channels, each of the plurality of image processing channels being configured to perform an image signal processing operation, the image signal processing core being configured to generate a plurality of output unit signals by receiving and processing the first and second plurality of processing unit signals in parallel through one or more of the plurality of image processing channels;
• a channel combiner configured to combine the plurality of output unit signals and generate at least one output signal stream;
• and
• a configuration controller configured to control, according to an operation mode, at least one of a number of the first plurality of processing unit signals, a number of the second plurality of processing unit signals, selection of a frequency of a processing clock signal that is used to provide the first and second plurality of processing unit signals in parallel to the image signal processing core, and makeup of the combination of the plurality of output unit signals,
• wherein a number of image processing channels that are allocated to process the first plurality of processing unit signals and a number of image processing channels that are allocated to process the second plurality of processing unit signals, from among the plurality of image processing channels, vary based on at least one of the operation mode, the number of the first plurality of processing unit signals, and the number of the second plurality of processing unit signals.

An image signal processing device comprising:

• a channel converter that receives an input signal stream from an image sensor, and divides the input signal stream into one or more processing unit signals;
• an image signal processing core, comprising a plurality of image processing channels, that performs an operation on the one or more processing unit signals to generate one or more output unit signals,
• wherein the image processing channels operate in parallel;
• and
• a channel combiner that combines the one or more output unit signals to generate the output signal stream.
