Publication number: 20240098215Abstract: Disclosed are a signal processing device and an image display apparatus including the same. The signal processing device of an embodiment of the present disclosure includes: a quality calculator configured to calculate a source quality of an image signal received from an external settop box or a network; an image quality setter configured to set an image quality of the image signal based on the calculated source quality; and an image quality processor configured to perform image quality processing on the image signal based on the set image quality, wherein in response to the source quality of the received image signal being changed at a first time point, the image quality setter changes an image quality setting sequentially from a first setting to a second setting; and based on the image quality setting, the image quality processor performs image quality processing. Accordingly, flicker may be reduced when an image quality is changed due to a change in the source quality of the received image signal.Type: ApplicationFiled: November 29, 2023Publication date: March 21, 2024Applicant: LG ELECTRONICS INC.Inventors: Saem PARK, Seokpan KANG, Yongtaek GONG, Sangchurl NAM, Yeonoh NAM, Jeonghyu YANG, Kyungmee LEE, Myongyoung LEE, Seoksoo LEE, Wonwoo LEE, Seungjong CHOI, Jongwoo HA
