Abstract: An operation method of an image signal processing device includes receiving a raw pixel code from an external image sensor device including an image pixel, generating a non-linear pixel code by performing non-linear mapping on the raw pixel code, and outputting a downsized pixel code obtained by performing a masking operation on bit positions including a first bit position corresponding to a most significant bit of the non-linear pixel code and a second bit position corresponding to a least significant bit of the non-linear pixel code. An amplitude of the raw pixel code is linear to illuminance of a light incident onto the image pixel, an amplitude of the non-linear pixel code is non-linear to the amplitude of the raw pixel code, and the non-linear pixel code has a first code length, and the downsized pixel code has a second code length smaller than the first code length.

Abstract: The present invention relates to a heteroaryl derivative compound and a use thereof. Since the heteroaryl derivative of the present invention exhibits excellent inhibitory activity against EGFR, the heteroaryl derivative can be usefully used as a therapeutic agent for EGFR-associated diseases.

Abstract: A smoking article case with a hand care function may be provided. The smoking article case according to some embodiments of the present disclosure includes a body portion in which an inner space for storing a smoking article is formed and a cover which is connected to the body portion, wherein a functional care zone may be formed on at least a portion of an outer surface of the body portion and an outer surface of the cover. Microcapsules containing a functional material are applied on the functional care zone, and as the microcapsules are crushed by a smoker's rubbing motion and the functional material is discharged from the crushed microcapsules, the hand care function may be provided to the smoker.

Abstract: An embodiment of the present disclosure provides a method of flavoring and aging smoking materials, the method including: adding a flavoring, which is diluted in a base solution, to a smoking material; and aging the smoking material, to which the flavoring is added, under constant temperature and humidity conditions.

Abstract: Provided are methods of operating a gateway and a server, performing an intelligent negotiation in an Internet of Things (IoT) network. According to an example embodiment, a method of operating the gateway of an IoT system includes receiving status information from at least one of a plurality of end devices included in a local network, determining whether to start a negotiation based on a status of the local network that is analyzed based on the status information, transmitting a negotiation request to an external device, receiving a suggestion corresponding to the negotiation request from the external device, and transmitting a reply indicating whether to accept the suggestion to the external device.
