There is provided an image processing apparatus. An obtaining unit obtains an image, and first NR information defining noise reduction processing using a first noise reduction processing method which an external apparatus can apply to the image. A generating unit generates, on the basis of the first NR information, second NR information defining noise reduction processing using a second noise reduction processing method which is different from the first noise reduction processing method. A noise reducing unit applies the noise reduction processing using the second noise reduction processing method to the image in accordance with the second NR information.

A method for image-processing and an electronic device are disclosed. The method includes: obtaining a RAW image packet comprising at least two RAW images, the at least two RAW images having different exposure durations; unpacking the RAW image packet and obtaining the at least two of RAW images; obtaining a High Dynamic Range (HDR) RAW image by performing an image synthesis operation on the at least two RAW images; and performing a previewing, photographing, or video-recording operation on the HDR RAW image.

The present invention relates to a signal processing apparatus and an image display apparatus including the same. The signal processing apparatus for processing a baseband signal demodulated from an RF signal, includes: a synchronizer; a channel estimator; an equalizer; an error corrector to perform error correction based on a signal output from the equalizer; and a mean square error calculator to calculate a mean square error based on a difference between an input signal from the equalizer and a reference signal, wherein when the RF signal includes a co-channel interference signal, the error corrector performs error correction by using a mean square error in a time domain or mean square errors in a time domain and a spatial domain. Accordingly, a baseband signal, from which a defect is removed, may be obtained in response to various communication channels or broadcast channels.
