The method includes receiving image data for a first pixel of a captured image, receiving image data for a second pixel of the capture image, determining a first saturation value of the first pixel and a second saturation value of the second pixel, determining a maximum saturation value based on the first saturation value and the second saturation value, and rendering a subpixel value using a one dimensional filter or a unity filter based on the determined maximum saturation value.
Abstract:
An image processing apparatus and an image-processing method are provided. The image processing method includes encoding an image according to a first encoding type, encoding the image, which has been encoded according to the first encoding type, according to a second encoding type, and decoding the image, which has been encoded according to the second encoding type, in which the second encoding type is contrast dependent encoding (CDE) which is dependent on a contrast of the image.
Abstract:
A side-channel encoding method for an electronic device is provided. The side-channel encoding method includes converting an original image into a down image by downscaling the original image, converting the down image into an up image by upscaling the down image, calculating a pixel-specific luminance variation between the original image and the up image by using a local average luminance for each pixel included in the original image, converting the pixel-specific luminance variation into a first variation binary signal by binarizing the luminance variation, converting the first variation binary signal into a second variation binary signal by simplifying the first variation binary signal, and outputting the second variation binary signal by including the second variation binary signal in the down image.
