Abstract: A dust detection system, comprising a receiver, a dust extraction block, a memory and an image correction block, is provided. The receiver receives an image signal. The dust extraction block generates a dust image signal on the basis of the image signal. The memory stores an intrinsic-flaw image signal corresponding to an intrinsic-flaw image including sub-images of dust that the dust extraction block extracts in initializing. The image correction block generates a corrected dust-image signal on the basis of the intrinsic-flaw image signal and a normal dust-image signal. The normal dust-image signal corresponds to a normal dust image including sub-image of dust that the dust extraction block extracts after initializing. The corrected dust image is the normal dust image that sub-images of dust in the intrinsic-flaw image are deleted from.

Abstract: A photographing apparatus comprises an imaging sensor, a memory, and a display unit. The imaging sensor obtains image data. The memory stores the image data. The display unit indicates a still picture based on the image data and a white balance setting picture on the still picture. The white balance setting picture is used for setting a white balance gain in a white balance adjustment.

Abstract: Original image data has original luminance data and color difference data. The original luminance data is separated into first luminance data and second luminance data. The second luminance data undergoes low-pass filter process so as to produce the third luminance data. The first luminance data and the third luminance data are synthesized. Due to this, the soft focus picture image, which consists of the synthesized luminance data and the difference luminance data, is generated.

Abstract: The image resolution of an original image is reduced, so that the original image is changed to a low-resolution image. Here, a bi-linear interpolation or a bi-cubic convolution is carried out for the resolution reduction. Pixel data from each pixel of the low-resolution image is filtered by a low-pass filter. Due to this, the low-resolution image changes to a filtered image. The number of pixels forming the filtered image is restored to the number of pixels forming the original image to generate a restored image. In the restored image, the contours of the objects are sufficiently unclear even if a small matrix is used in the filtration.

Abstract: An image-processing device is provided that comprises an input device and an image-processing unit. The input device inputs video signals of an original color image. The image-processing unit carries out a predetermined image altering process on luminance components of the video signals. The luminance components, which are subjected to the image altering process, and color-difference components of the video signals are combined. Thereby, video signals for an illustrational image, in which the outlines of the image features are made bold and the number of colors is reduced with respect to the number of colors in the original color image, are generated.
