US 2021/0279899 A1 · IMAGE SENSING DEVICE AND OPERATING METHOD THEREOF

Abstract

An image sensing device includes an analysis module suitable for analyzing, based on pixel values of a kernel, an image texture of the kernel including a target pixel group and one or more adjacent pixel groups, a sum module suitable for generating any one of a first target sum value and a second target sum value based on an analysis result of the analysis module, wherein first target sum value is obtained by applying texture characteristics of the kernel in target pixel values of the target pixel group and the second target sum value is obtained without applying the texture characteristics of the kernel in the target pixel values, and a processing module suitable for generating a sum image based on any one of the first and second target sum values.
