摘要： The present invention relates to a control method of a photographing apparatus, the photographing apparatus and a control program, which are capable of automatically determining a photographing mode capable of generating a sharper image. If a first exposure time is equal to or shorter than a first threshold value, a control circuit 18 makes a decision to take an input image in a first mode. The first exposure time is an exposure time required for taking one input image on the assumption that a photographing operation is carried out in the first mode for generating one output image by taking one input image. If the first exposure time is neither equal to nor shorter than the first threshold value, on the other hand, the control circuit 18 makes a decision to take a plurality of input images in a second mode provided that a second exposure time is equal to or shorter than a second threshold value. The second exposure time is an exposure time required for taking each of the input images successively on the assumption that a photographing operation is carried out in the second mode for generating one output image by taking the input images successively. The present invention can be applied for example to a digital camera.

摘要： A display device including a camera is used by inserting it in the direction of a user's gaze. Alternatively, an image of the same area as that of a scene from a windshield of an automobile may be obtained and the image may be displayed by using an information providing apparatus installed in the automobile. A system provides information to the user by adding a two-dimensional or three-dimensional computer graphics object to an image taken by the camera. The information is directly added to a scene in the direction of the user's gaze and is displayed to the user. Thus the user can easily understand the relationship between the information and the position to which the information is added.

摘要： In the case a two-dimensional image (FIG. 11A) displaying a house-shaped three-dimensional object is stored in a noted buffer, when shape information indicating that a check-patterned wall is rectangular and the four apexes of the wall as characteristic points are designated by a user, a spread image (FIG. 11B) obtained by spreading the check-patterned wall onto a two-dimensional plane is generated on the basis of the shape information and characteristic points and is stored into a paste buffer. Then, a two-dimensional image of a column (FIG. 11C) is stored into the noted buffer. When shape information indicating the lateral side of the column and a predetermined point on the lateral side as a characteristic point are designated by the user, the image (FIG. 11B) stored in the paste buffer is pasted to the lateral side of the column in the noted buffer (FIG. 11D) on the basis of the shape information and characteristic point. Thus, the user can easily perform three-dimensional editing or the like on a two-dimensional image.

摘要： The invention provides an image connecting method, an image connecting apparatus, and a storage medium on which an image connecting program is stored, for connecting a first image and a second image such that particular connecting areas are determined for the first image and the second image and the first and second images in the connecting areas are combined together thereby connecting the first and second images into a single image including no unnatural parts. The first image and the second image are decomposed into frequency components. The connecting area is determined for each frequency component such that the connecting area becomes narrower with the increase in the frequency of the frequency component, and the first and second images are combined in the connecting area for each frequency component. After that, particular partial images in the first and second images are designated. The designated partial images are extracted from the first or second image, and extracted partial images are overwritten on the connecting part.

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.
