摘要： A simple, compact optical system is provided that includes a transmissive optical element and a HOE but that nevertheless does not require an extra optical element for the correction of chromatic aberration. The HOE is designed to have diffractive efficiency for each of R, G, and B light beams and have different focal lengths for those light beams so as to correct the longitudinal chromatic aberration produced by a rectangular parallelepiped prism. This eliminates the need for an extra means for correcting the chromatic aberration produced by the prism. The HOE may be designed to exhibit different angles of diffraction for the R, G, and B light beams so as to correct the chromatic aberration produced perpendicularly to the optical axis by a wedge-shaped prism.

摘要： A digital camera of the invention has an LCD and an EVF. In a third display mode, a whole image is displayed on the LCD, a frame is displayed in the central area, and an image in the central area (within the frame) is enlargedly displayed on the EVF. An enlarged display icon is displayed on the LCD to thereby notify the user of the enlarged display on the EVF. The image capturing range can be confirmed on the LCD, and automatic focusing is performed on the basis of the image in the central area, so that focus can be also confirmed on the EVF. Consequently, according to the invention, both the image capturing range and the focus can be confirmed in the digital camera and an image can be efficiently captured.

摘要： An image processing apparatus first forms an edge image of an input image using, for example, SOBEL operator, and performs a smoothing process on the formed edge image by using an average filter. Thereafter, the image processing apparatus calculates a difference between the edge image and the edge smoothed image, and binarizes the edge image based on the difference.

摘要： The digital camera has the function of registering a captured image or the like in an album file and includes a display such as an LCD and a switch button (QV button) for switching a display image on the display. An image to be displayed on the display is changed in response to depression of a switch button among a live view image in a capturing mode, a reproduction image regarding a data file in a reproduction mode, and an album image regarding an album file in an album reproduction mode. For example, in response to depression of the switch button, the images are sequentially displayed in the above-described order. Preferably, when a captured file is not stored, a reproduced image is not displayed. When an album file is not registered, an album image is not displayed.

摘要： Disclosed is a monitoring camera 2 and a monitoring system 1 including the camera 2 and a controller 3 which are interconnected with each other through a communication network. The camera is provided with a distortion lens for forming an image with the distortion being less and height of image is large in the central area of the image while the distortion being large and height of image is small in the peripheral area of the image. With that distortion lens, the camera forms a clear and large image of an object in the central area. The camera is switchable between a stand-by mode for outputting data of image of a wide area, and a close-observation mode for outputting data of the image of the central area extracted from the entire image. In the close-observation mode, the camera may track the movement of an object which intruded into the monitored area.

摘要： In order to suppress undesired influence of interpolation at the time of color-converting image data, a link file generating program makes a computer execute the steps of coupling a monitor profile and a printer profile to generate a link file linking display-dependent colors (RGB data) to printer-dependent colors (CMYK data), and correcting the link file to adapt a printer-dependent color related to a prescribed one of the display-dependent colors to said prescribed one. Using a display-dependent color as a reference, a printer-dependent color related to the reference color is corrected. Accordingly, a link file can be generated that suppresses the undesired influence of interpolation at the time of color-converting the image data.

摘要： The present invention provides a database system capable of dealing with dynamic changes in an event that vary continuously with time. A database system outputs a retrieval output from data in response to a user's retrieval request on the basis of a retrieval logic. The retrieval logic is allowed to evolve on the basis of a logical model. This logical model establishes a general relationship which leads results from conditions relating to a group of events that are dealt by a data group. Moreover, a database system optimizes a data structure on the basis of the logical model. The logical model can be transferred in a separated manner from the specific data contents of the data group. Therefore, the logical model can be exported to another database system of the same kind, and also imported from another data base system of the same kind.

摘要： An object of the present invention is to realize an image processing technique of making chromatic aberration correction excellently function and capable of efficiently correcting a chromatic aberration and to reduce storage capacity of parameters used for the chromatic aberration correction. It is constructed so that an image processing unit concurrently performs a chromatic aberration correcting process of correcting a chromatic aberration by an image capturing optical system and a color interpolating process of interpolating a dropout color component pixel by pixel on an image signal obtained from an image capturing device. On the basis of position information of a pixel to be processed obtained from the image processing unit, a control unit determines an image filter to be applied to the pixel. For example, an image filter is generated by combining a filter for chromatic aberration correction and a filter for color interpolating process. The image filter is applied, filter computation is performed on the image signal, and the chromatic aberration correcting process and the color interpolating process are concurrently performed.
