Zusammenfassung:The present disclosure provides a quantization apparatus and method, and an image processing apparatus, capable of improving operation efficiency while suppressing performance degradation due to quantization errors by receiving one of a plurality of matrices obtained for neural network operation in an artificial neural network as an input matrix, dividing the input matrix into a plurality of channels, selecting a quantizer for each channel by analyzing the distribution of element values included in each of the plurality of divided channels, and quantizing element values included in the channels using the selected quantizer.
