Abstract
An image enhancement apparatus and method based on luminance information of a pixel. The image enhancement apparatus may determine luminance data of each of a plurality of pixels, and may adaptively determine a conversion ratio according to the luminance data to apply the conversion ratio to an input image, thereby performing image-enhancing. The image enhancement apparatus may adaptively converse the input image according to luminance data, thereby precisely and effectively performing image-enhancing.
Claims19
An image enhancing apparatus, the apparatus comprising:
- a luminance data determining unit to determine luminance data of each of a plurality of pixels constituting an input image;
- a gamma constant determining unit to determine a gamma constant of each of the pixels using the luminance data;
- and
- an image-enhancing performing unit to perform image-enhancing upon the input image using an image conversion ratio based on the gamma constant.
An image enhancing method, the method comprising:
- determining luminance data of each of a plurality of pixels constituting an input image;
- determining a gamma constant of each of the pixels using the luminance data;
- and
- performing image-enhancing upon the input image using an image conversion ratio based on the gamma constant.
