摘要： A spectral image sensor includes: a first lens system; an infrared blocking filter; a second lens system configured to adjust a chief ray angle (CRA) of oblique incident light to reduce an incident angle of the oblique incident light with respect to a spectral filter; the spectral filter; and an image sensor. The image sensor may be configured to detect light passing through the first lens system, the infrared blocking filter, the second lens system, and the spectral filter.

摘要： An example electronic device and an example control method thereof are provided. The example electronic device may include: a memory configured to store information about a plurality of intonation templates, which are obtained by training an intonation template generator based on a plurality of voice signals and represent intonations of the plurality of voice signals; and a processor configured to, when a voice signal is received, obtain information about a user’s intention corresponding to the voice signal, obtain first text to respond to the voice signal, based on the voice signal and the information about the user’s intention, identify an intonation template corresponding to the first text based on the information about the plurality of intonation templates by inputting information about the first text to an intonation classifier, obtain intonation information corresponding to the identified intonation template by inputting information about the identified intonation template to the intonation encoder, and obtain an output voice signal corresponding to text by inputting the first text and the intonation information to a voice synthesis module.
