Original Abstract Submitted
an image processing device is provided. the device includes: a processor configured to: perform first tone mapping on an input image frame using a brightness enhancement tone curve corresponding to a current ambient illuminance value to obtain a first result; obtain histogram tone curves by applying a variable contrast limit to a plurality of histograms respectively corresponding to a plurality of sub-images, constituting a previous image frame; perform second tone mapping on the input image frame by interpolating the histogram tone curves to obtain a second result; and provide output image data by performing third tone mapping on the input image frame based on the first result and the second result. the brightness enhancement tone curve corresponds to a first human vision system (hvs) response to a reference ambient illuminance value and a second hvs response to a target ambient illuminance value.
