摘要： An image processing apparatus and method for generating high-sensitive, high-brightness color images are disclosed. A second image having a wider band and higher-sensitivity than those of a first image which includes color information may be acquired, wherein the first and second images are images captured from a scene. A first transformed image having high brightness may be generated by performing binning on the first image, and edge information being a high-frequency component may be extracted from the second image. A high-brightness, high-sensitive color image may be generated using the first transformed image and the edge information.

摘要： Provided are an image brightness controlling apparatus and method, and an adaptive brightness controlling apparatus and method based on the brightness degree and/or brightness range of an image. The image brightness controlling apparatus includes a brightness increment arithmetic unit for outputting a brightness increment for a pixel, and an individual component brightness increment arithmetic unit for outputting the brightness increments of individual components constituting the pixel in response to the brightness increment for a pixel. The individual component brightness increment arithmetic unit multiplies the brightness increment of the pixel by each of the unit vectors of the components constituting the pixel to obtain the brightness increments of the individual components. The image brightness controlling apparatus further includes an adder for adding the components constituting the pixel to the brightness increments of the components. The image brightness controlling apparatus and the adaptive image brightness controlling apparatus can maintain the sense of color of an image (e.g., the hue or chroma of an image) while increasing the brightness degree and brightness range of an image.

摘要： A method and apparatus for measuring a color-texture distance and a method and apparatus for sectioning an image into a plurality of regions using the measured color-texture distance are provided. The method of measuring a color-texture distance includes the steps of: assigning different degrees of importance to a brightness difference, a saturation difference, and a hue difference between two points in a color feature space constituted of color feature values of pixels in an image, and adding the brightness difference, the saturation difference, and the hue difference in proportion to the assigned degrees of importance to calculate a color distance between the two points; obtaining a texture distance between the two points using a difference between texture feature values of the two points and weighting coefficients applied to multi scales of a texture, in a texture feature space constituted of texture feature values for the pixels; and multiplying a color weight value and a texture weight value by the color distance and the texture distance, respectively, adding the multiplication results to each other, and obtaining the color-texture distance between the two points. The degrees of importance are determined on the basis that a hue is more important than a brightness or a saturation, a color becomes black as the brightness approaches an absolute value, and the hue has an arbitrary value as the saturation approaches the absolute value.
