Abstract
An image sensing device, and a method of operating the same, includes an image sensor and an image processor. The image sensor is configured to sense light sourced from a subject and generate an image layer. The image processor is configured to generate a feature map by performing a convolution operation on the image layer and a fixed-size kernel, generate a final feature map by performing convolution operations on a variable-size kernel and the feature map, and generate image data including channels in which the final feature map is classified for each color.
Claims20
An electronic device comprising:
- an image sensor configured to sense light sourced from a subject and generate an image layer;
- and
- an image processor configured to:
- generate a feature map by performing a convolution operation on the image layer and a fixed-size kernel;
- generate a final feature map by performing convolution operations on a variable-size kernel and the feature map;
- and
- generate image data including channels in which the final feature map is classified for each color.
A method of operating an electronic device, the method comprising:
- converting an image of a subject into an image layer;
- generating the image layer as an initial feature map by performing a convolution operation using a fixed-size kernel;
- comparing a size of the subject included in the initial feature map with a size of a receptive field;
- generating a plurality of feature maps by adjusting the size of a variable-size kernel and the receptive field according to a comparison result;
- and
- generating channels in which a final feature map among the plurality of feature maps is classified for each color, and generating feature data including the channels.
