Abstract
An image signal processor includes a resolution converter configured to generate at least two images based on image data including color pixel values and white pixel values, an element processor configured to extract texture information using converted color pixel values and converted white pixel values included in each of the at least two images and to generate at least two processed images based on the extracted texture information, a synthesizer configured to generate a composite chrominance image and a composite white image by synthesizing the at least two processed images, and an image acquisition circuit configured to generate an output image based on the image data, the composite chrominance image, and the composite white image.
Claims20
An image signal processor comprising:
- a resolution converting circuit configured to generate at least two images based on image data including color pixel values and white pixel values;
- an element processor configured to extract texture information, and to generate at least two processed images based on the extracted texture information;
- a synthesizer configured to generate a composite chrominance image and a composite white image by synthesizing the at least two processed images;
- and
- an image acquisition circuit configured to generate an output image based on the image data, the composite chrominance image, and the composite white image,
- wherein the element processor further includes:
- a first texture determiner configured to determine a texture based on a first converted color pixel values and a first converted white pixel values included in each of the at least two images, and to output texture information and a synthetic image obtained by conversion of the texture information.
