摘要： A method for digitally processing motion image signals comprises the steps of: (a) obtaining digital motion image signals that originated from a sequence of motion picture frames; (b) using a frame averaging technique to reduce noise in the digital motion image signals, thereby producing noise-processed motion image signals; and (c) producing output digital motion image signals by sharpening the noise-processed motion image signals with a sharpening filter designed in the spatial domain with a 2D kernel that increases the noise in order to provide a desired grain response.

The then developing video signals are evaluated for their high frequency component. The objective is adjusted to the maximum of the high frequency component.

摘要： In video scratch repair, scratches are treated as additive pedestals which are constant or slowly changing along the scratch. For a given picture, these pedestals are estimated and subtracted from the video input to reveal original picture detail. The pedestal can be estimated by heavily filtering along the direction of the presumed scratch, the output of a prior art scratch detector.

摘要： An image processing device and method to select a field to use in interpolation, if an input image is a film image. The image processing device includes a field selector to select a field to use to interpolate a current field based on difference values in field data among first, second, and third fields being consecutively input in an input image, the field to use to interpolate the current image being one of the first and the third fields and the current field being the second field, a film detector to generate a pattern based on the difference values in the field data between the first, second, and third fields and to determine whether the input image is a film image based on the generated pattern, and an interpolator to interpolate the second field using the one of the first and third field selected by the field selector if the film detector determines the input image to be a film image. Accordingly, when the input image is a film image without a bad-edit, the interpolation process is executed by selecting two temporarily consecutive fields of a field to be interpolated, and using the field with a smaller difference values in field data from the field to be interpolated and a problem of judder in images can be resolved.

摘要： A method is disclosed for showing motion picture films at a frame rate higher than that in which the films were originally shot. This method uses computer software originally designed to generate cinematic images for a slow-motion effect to produce images for interpolation between each of the discrete images of an existing motion picture. The resulting film contains twice as many images as the film did when originally photographed, with a computer-generated “in between” image placed between each pair of successive images in the original film. These new transitional images simulate the appearance of motion that would have been captured by a camera, if twice as many discrete images had been photographed than actually were photographed in the original production. This method is especially suited to presentation of motion picture films on large theatrical screens. The method disclosed can be used for modification of films, by adding computer-generated images to only certain scenes or sequences of film action. This allows the effect created by this method to be added or removed at the discretion of the user of the method.
摘要翻译：公开了一种用于以比最初拍摄胶片的帧速率更高的帧速率显示电影胶片的方法。该方法使用最初设计的计算机软件来生成用于慢动作效果的电影图像，以产生用于现有运动图像的每个离散图像之间的插值的图像。所得到的胶片包含当胶片在最初拍摄时所拍摄的图像的两倍，其中计算机生成的“图像”位于原始胶片中的每对连续图像之间。这些新的过渡图像模拟了相机拍摄的运动的外观，如果拍摄的离散图像是原始制作中拍摄的两倍。这种方法特别适用于在大型戏剧屏幕上呈现电影胶片。所公开的方法可以通过将计算机生成的图像仅添加到某些场景或胶片动作的顺序来用于胶片的修改。这允许由方法用户自行添加或删除由此方法创建的效果。

摘要： Luminance of defective pixels is adjusted. A target pixel is selected form the plurality of defective pixels. A normal pixel is searched and detected on each of opposed sides across the target pixel along each of a plurality of search lines extending through the target pixel. There are calculated a first pixel value ratio which is a ratio between a pixel value of one normal pixel located on one side across the target pixel and a pixel value of a further normal pixel located on the other side across the target pixel, a second pixel value ratio which is a ratio between the pixel value of said one normal pixel and a pixel value of the target pixel after the luminance adjustment thereof, and a third pixel value ratio which is a ratio between the pixel value of the further normal pixel and the pixel value of said target pixel after the luminance adjustment thereof. A weight coefficient for each search line is calculated, based on the first, second and third pixel value ratios. An interpolation value for the target pixel is calculated for each search line. Then, a correction value for the target pixel is calculated, based on the weight coefficient for each search line and the interpolation value for the target pixel, and the target pixel is corrected based on the correction value.

摘要： An image reading device which has a reduced size and which can read images at high quality. LEDs, which are respective pluralities of light emitting diode elements that emit red, green, blue and infrared light, are disposed at an area CCD scanner. A frame image of a photographic film is successively read with light of each wavelength by emitting light from the LED elements. Pixels that are affected by a scratch or dust at the photographic film are detected by the infrared light. Red, green and blue image data for such pixels is corrected by means of interpolation or the like. Thus, images can be read at high quality. Furthermore, because the LEDs are used as a light source instead of a halogen lamp, less heat is emitted, the device is more compact, and cut filters and the like are not needed.

摘要： A lamp, a film guide, and a photosensitive detector are combined into an optical system contained in a portable device that generates electrical signals representing images recorded on motion picture film. The film guide has a surface proximate to the motion picture with an aperture therein through which light from the lamp passes to image the film on the photosensitive detector. A digital processor, which is electrically connected to the photosensitive detector processes an electronic signal output by the photosensitive detector. To provide compactness, the optical system has a folded path comprising three segments each separately mounted on a different surface. The first segment includes the lamp, the second includes the film guide, and the third includes the photosensitive detector. An optical detector positioned so as to receive light from the lamp enables adjusting the device when the device is moved to a location where the temperature and other environmental conditions change. This configuration also finds use when the device is located in an environment whose temperature remains consistently hot.
