摘要： An apparatus and a method for efficiently executing correction of false color, such as purple fringe, caused by chromatic aberration and for generating and outputting high-quality image data are provided. A white-saturated pixel is detected from image data, a false-color-pixel detection area is set around the detected white-saturated pixel, and pixels having color corresponding to false color such as purple fringe are detected from the set area. The detected pixels are determined as false-color pixels and correction processing based on the values of the surrounding pixels is performed on the determined false-color pixels. With this configuration, an area of false color such as purple fringe generated in the neighborhood of a white-saturated pixel can be efficiently detected, pixel values can be partially corrected, and high-quality image data can be generated and output without affecting the entire image.

摘要： The space of the two-dimensional blinking pattern is divided into a plurality of resolution sub-spaces onto which the data to be transmitted is mapped in an encoding process. A data-receiving apparatus with a resolution thereof reduced to an insufficient level due to a long distance between the data-receiving apparatus and the data-transmitting apparatus is capable of reading a two-dimensional blinking pattern obtained as a result of a process to encode the data to be transmitted in a low-resolution sub-space. On the other hand, a data-receiving apparatus with a sufficient resolution is capable of reading a two-dimensional blinking pattern resulting from a process to encode the data to be transmitted in a high-resolution sub-space. As a result, even if a data-receiving apparatus is at a location far away from the data-transmitting apparatus, the data-receiving apparatus is capable of obtaining information to a certain degree, allowing a person carrying the data-receiving apparatus to form a judgment as to whether or not it is necessary for the person to approach the data-transmitting apparatus in order to obtain more detailed information.

摘要： A first original image and a second original image are input to create a merged image. A superimpose area, which an operator designates using an input device, is set as a superimpose area. A portion of the first original image to be superimposed is determined. A superimposing process is executed by blending the first original image with the merged image with a weighted average. The setting of the superimpose area is to determine an &agr; value indicative of the degree of blend (weight) between the first original image and the merged image. The &agr; value of a portion independently present to the side of the second original image with respect to a center line is forced to be zero. The first original image is superimposed onto the merged image using the determined &agr; value.
