Abstract: An artificial neural network (ANN) system includes a processor, a virtual overflow detection circuit and a data format controller. The processor performs node operations with respect to a plurality of nodes included in each layer of an ANN to obtain a plurality of result values of the node operations and performs a quantization operation on the obtained plurality of result values based on a k-th fixed-point format for a current quantization of the each layer to obtain a plurality of quantization values. The virtual overflow detection circuit generates a virtual overflow information indicating a distribution of valid bit numbers of the obtained plurality of quantization values. The data format controller determines a (k+1)-th fixed-point format for a next quantization of the each layer based on the generated virtual overflow information. An overflow and/or an underflow are prevented efficiently by controlling the fixed-point format using the virtual overflow.

Abstract: An electronic device is disclosed. The electronic device includes a camera, a communication module, and a processor. The processor is operably coupled with the camera and the communication module. The processor is configured to obtain a first image corresponding to an external object using the camera. The processor is also configured to generate a second image smaller in data size than the first image using the first image. The processor is further configured to transmit the second image to an external electronic device through the communication module. The processor is also configured to receive correction area information from the external electronic device through the communication module. The correction area information is based on information associated with an image area identified from the second image. The processor is further configured to perform correction using the first image based on at least part of the correction area information.
