Patent ID: 8810675

Claim:
An image processing apparatus comprising: a plurality of image processing blocks that are capable of real-time processing of an image signal inputted from outside, said plurality of image processing blocks including a spatial filtering block that applies a spatial filtering to an input signal, said spatial filtering block including, a first low-pass filter that performs a first low-pass filtering; a programmable spatial filter; and a first operator that subtracts a first low-pass filter output signal that is an output signal of said first low-pass filter from a center pixel signal that is an original pixel signal, so as to generate a high-frequency component, wherein said spatial filtering block is capable of simultaneously outputting at least two signals of said first low-pass filter output signal, a signal output from and filtered by said programmable spatial filter, and said high-frequency component, when said programmable spatial filter is set as a low-pass filter, said at least two signals include said high-frequency component, and when said programmable spatial filter is set as a high-pass filter, said at least two signals include said first low-pass filter output signal.
