Image signal processor, operation method of image signal processor, and electronic device

An image signal processor includes a first sharpening filter configured to perform a first filtering operation on a raw data output from an external image device to output first sharpness data. A second sharpening filter is configured to perform a second filtering operation on the raw data in parallel with the first filtering operation to output second sharpness data. An edge determiner is configured to determine an edge strength of an image corresponding to the raw data based on the raw data and to adjust a first weight and a second weight based on the determined edge strength. A combiner configured to combine first weight data in which the adjusted first weight is reflected in the first sharpness data and second weight data in which the adjusted second weight is reflected in the second sharpness data to generate output data. 一种图像信号处理器，包括：第一清晰化滤波器，被配置为对从外部图像设备输出的原始数据执行第一滤波操作，以输出第一清晰度数据。第二清晰化滤波器被配置为与第一滤波操作并行地对原始数据执行第二滤波操作，以输出第二清晰度数据。边缘确定器被配置为基于原始数据确定与原始数据相对应的图像的边缘强度，并且基于所确定的边缘强度来调整第一权重和第二权重。组合器被配置为将调整后的第一权重反映
