First image data is obtained by performing an image capturing operation with a flash and, subsequently, second image data is obtained by performing an image capturing operation without a flash. By using data of a differential image between the first and second image data and a relative spectral distribution of flash light, the spectrum reflectivity in a position on a subject corresponding to each pixel is obtained and object-color component data is acquired as data from which an influence of an illumination environment has been removed. On the other hand, illuminant component data indicative of spectral distributions of a plurality of illumination light are prepared. By combining arbitrary illuminant component data to the obtained object-color component data, an image with a different illumination environment can be reproduced.

An object tracking apparatus tracks an object on image data captured continuously. The object tracking apparatus includes an object color adjusting unit and a particle filter processing unit. The object color adjusting unit calculates tendency of color change in regions on image data and adjusts a color of the object set as an object color based on the tendency of color change to obtain a reference color. The particle filter processing unit estimates a region corresponding to the object on image data based on likelihood of each particle calculated by comparing a color around each particle with the reference color, using particles which move on image data according to a predefined rule.

The present invention is directed to improving the accuracy of white balance adjustment. An image input from an image capture device 10 is divided into blocks, and white balance gains are calculated from a representative value of each block. Prior to calculation of the representative value of each block, a color range determining circuit 13 determines whether each pixel included in each block belongs to a light source color range, or belongs to an apparent object color range. A representative value of that block is calculated from remaining pixels other than pixels determined to belong to the apparent object color range. Thus, by preventing the representative value from being affected by an object color, the accuracy of white balance gains is improved.

A process for object identification comprising extracting object shape features and object color features from digital images of an initial object and storing the extracted object shape features and object color features in a database where said extracted object shape features and object color features are associated with a unique identifier associated with said object and repeating the first step for a plurality of different objects. Then extracting object shape features and object color features from a digital image of an object whose identity is being sought and correlating the extracted object shape features and object color features of the object whose identity is being sought with the extracted object shape features and object color features previously stored in the database. If a first correlation of the extracted object shape features is better than a first threshold value for a given object associated with an identifier in the database and if a second correlation of the extracted object color features is better than a second threshold value for the given object, then making a determination that the object whose identity is being sough is said given object.

The present invention provides a technique capable of promptly and easily acquiring object color component data of a plurality of subjects even if the spectral distribution of light illuminating said plurality of subjects is not known in advance. For example, under predetermined conditions of irradiating a subject with predetermined illumination light by using an electronic flash, an image input system captures an image of a first subject to thereby acquire first color image data. On the basis of the acquired first color image data, the image input system estimates first object color component data of the first subject. After that, the image input system captures an image of the first subject in unknown illumination environments to thereby acquire second color image data. By using the first object color component data and the second color image data, the image input system estimates the spectral distribution of unknown illumination. Subsequently, on the basis of the estimated spectral distribution of unknown illumination, the image input system calculates a conversion matrix for converting color image data of the subject acquired in the unknown illumination environments into object color component data.

The invention relates to a system and method for adjusting the color of image objects based on chained reference points and/or light gradients to account for the effects of lighting conditions that can vary across different environments, according to an implementation of the invention. To chain reference points and/or characterize light gradients, the system may determine a color shift value, which represents the effects of lighting conditions of a target environment (in which the lighting conditions may be unknown) relative to a reference environment (in which the lighting conditions may be known). The chained reference points, gradient characterization, color shift values, and/or other information may be used to store a delta map that characterizes the lighting conditions of an environment so that it may be reused for subsequent color shifts without re-characterizing the environment.

Adjustment object color space containing movement source partial color space including a color of an object of conversion processing and movement destination partial color space including a color in which the conversion processing is performed so as to inscribe the spaces is handled as a conversion object region. The inside of the conversion object region is moved toward a target color so that coordinates of an adjustment object overlaps with coordinates of a point after movement and the boundary of a movement region moves little or does not move at all. As a result of this, a phenomenon such as a color jump or gradation inversion occurs little in the boundary portion to the outside of an adjustment object region. Therefore, maintenance of gradation continuity of an image of a color adjustment object and prevention of color inversion can be combined to make partial color adjustment.
