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： In an imaging apparatus, a function whose value increases in time is used as a threshold electric-signal level, and an electric-signal level of a photoreceptor element is compared with the threshold electric-signal level. Even if a light received by the photoreceptor element has a low luminance, the electric-signal level of the photoreceptor element crosses the threshold electric-signal level in a short time, allowing calculation of the amount of optical energy received by the photoreceptor element. Furthermore, when an object having a region where brightness changes in time and also having a region with a low luminance is imaged, imaging interval is changed in accordance with luminance. Accordingly, information regarding how the brightness of the object is rapidly changing in time can be obtained more precisely, and an image can be output without making a projection image of the dark region completely black.

摘要： An image processing apparatus and an image processing method are disclosed by which an image correction process for a false color such as a purple fringe can be executed efficiently while excessive reduction of the saturation is prevented to produce image data of a high quality. A saturation reduction rate corresponding to each pixel is calculated, and saturation reduction of the pixel is executed based on the saturation reduction rate. Then, saturation correction is executed so that the difference between the hue of the pixel whose saturation has been reduced and a surrounding reference pixel may be reduced. Further, a surrounding pixel to be referred to in the saturation correction process is selected along a scanning line.
