In this image recording apparatus, imaging sensor obtains two video signals of different signal charge accumulation periods, in a given signal charge accumulation period which is represented by a field or a frame of a video signal, and the two video signals are recorded on a record medium, whereby a video signal of an object having a wide luminance distribution can be recorded, and as for the image reproducing apparatus, a correcting circuit corrects standard-illuminance video information and high-illuminance video information which are reproduced by a reproducing circuit, the user designates an object illuminance range to be output, through an object illuminance range designating circuit, and a level converter converts the luminance into a luminance level which can be output by a display apparatus or a printer, thereby allowing portions which are largely different in object illuminance, to be selectively displayed or output in reproduction.

An image printer for printing images with less cross-talk between images and less image flickering is provided. A plurality of images are interleft in one or a plurality of line units and a lenticular lens is used to make it possible for each individual pixel to be distinguished. The difference in brightness between an attentional pixel and the surrounding pixels that surround this attentional pixel is taken, and a correlation value is produced, the correlation value being reduced if the difference is large and increased if the difference is small. The image printer is equipped with a pixel shape controller that makes the printed pixels smaller in a region where the correlation value is low, and makes the printed pixels larger in a region where the correlation value is high.

A system for generating a digest of a moving image according to the present invention includes: a generating section for generating a moving image having a plurality of frames, and for generating an operation signal in response to an input received by the generating section during the generating of the moving image; a priority assigning section for assigning a priority to each of the plurality of frames as a function of the operation signal; a selecting section for selecting at least one image of a plurality of images corresponding to the plurality of frames, based on the priority; and an output section for outputting at least one image selected by the selecting section.

A video for one frame is captured and two adjacent frames are compared, the result of which is detected as a change degree of the video. Then, based on the magnitude of the change degree, it is determined whether a scene change (SC) exists. If an SC exists, it is examined whether its change degree alters rapidly or gradually, to determine the SC as a momentum or gradual SC. For the momentum SC, its determination point is detected as the momentum SC. For the gradual SC, its determination points is detected as the start of the gradual SC, thereafter, its end is detected. According, for one gradual SC, plural SC's are not detected and a midway illegible video is not indicated as an index picture.

Scene-change detection method that distinguishes between gradual and

A fuzzy data processing device includes a data input portion for inputting data and first and second fuzzy regression model memories for storing first and second fuzzy regression models, respectively. In each fuzzy regression model, all coefficients are denoted as fuzzy values. A fitting degree calculator is provided to calculate a degree of fitting of the first fuzzy regression model to the second fuzzy regression model. A maximum detector detects the maximum of the calculated fitting degree. Thus, the estimated value (y*) is obtained at which the maximum degree of the fitting of fuzzy values Yx and Yz, i.e., the grade peak point of the overlapping portion, is observed.
