摘要： PROBLEM TO BE SOLVED: To provide a forming method of a three-dimensional video sequence especially from the bundle of moving pictures captured from a scannerless distance visualizing system in a usual digital image processing.
SOLUTION: The sequence of three or more phase offset images is obtained in accordance with lighting to be modulated reflected from a scene. By this, the sequence includes a subsequence in which the successive phase offset images overlap with each other, and each subsequence forms the bundle of the images. That is, an image capture element includes a lighting device for lighting up the scene by using modulated lighting, an image modulating part which reflects the lighting to be modulated reflected from the scene to modulate it, and the bundle of the image layers of at least three phase offset images which are for capturing the image output by the image modulating part and add each phase delay corresponding to an objective distance in the scene from the lighting device. Each phase offset image of the bundle of the images is composed of the image capture element which adds a different phase offset for each image. The distance image is computed, therefore, from the corresponding bundle of the images by using the phase offset image, and by this a distance image sequence is formed.

摘要： PROBLEM TO BE SOLVED: To provide a method for photographing a panoramic image with an expanded dynamic range. SOLUTION: First, a plurality of images of a limited dynamic range captured by an image sensor are obtained. The plurality of digital images are stored and the storage digital images are then processed to create a synthetic image. Each synthetic image has an expanded dynamic range larger than that of the digital image itself. A plurality of synthetic images are used to create an expanded dynamic range panorama. Light attenuation data are stored together with the images to succeedingly reconfigure a panorama of a bit depth greater than that of an original panorama. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To obtain an extended dynamic range image of a scene from a plurality of limited dynamic range images captured by an image sensor in a digital camera. SOLUTION: A plurality of digital images comprising image pixels of the scene are captured by exposing the image sensor to light transmitted from the scene, and each image is evaluated after it is captured for an illumination level exceeding the limited dynamic range of the image for at least some of the image pixels. Based on the evaluation of each image exceeding the limited dynamic range, the light transmittance upon the image sensor is adjusted in order to obtain a subsequent digital image having a different scene brightness range. The plurality of digital images are stored, and subsequently the stored digital images are processed to generate a composite image having an extended dynamic range greater than any of the digital images by themselves.

摘要： PROBLEM TO BE SOLVED: To provide a scanner-less distance image system having a high dynamic range.
SOLUTION: The scanner-less distance image system having the high dynamic range has an illumination system for illuminating a scene with modulated illumination, and an image intensifying device including a modulation stage for receiving reflected modulated illumination and modulating the reflected modulated illumination from the scene. An image response element has an arrangement of individual pixels for capturing the image outputted from the image intensifying device, and the modulation of the reflected modulate illumination incorporates the phase delay corresponding to the distance of the matter in the scene from the distance image system. A transmission filter having a plurality of filter elements having the transmissivity of a spatially changing pattern is arranged in 1:1 mapping in related to the pixels for constituting the image response element. The transmissivity of the spatially changing pattern provides a plurality of separate exposures coupled in order to constitute one output image having a succeedingly expanded dynamic range.

摘要： PROBLEM TO BE SOLVED: To detect a face or faces of one or more persons in an image in order to improve the quality of the image captured by adding a value to an image capturing processing. SOLUTION: A method of determining the presence of a face from image data compares a face-shaped model with probability of a face in order to search for areas of faces becoming one or more candidates by previously screening image data by a first algorithm, and confirms the presence of the faces in the areas by searching for the face areas becoming the respective candidates by executing a second algorithm to the face areas becoming the candidates by pattern matching. By using the combination of the first and second algorithms, performance is enhanced in terms of a detection level as compared with the case where the first and second algorithms are individually used. A digital camera includes a memory for storing algorithms, and an electronic processing part for processing image data by an algorithm for determining the presence of one or more faces in a scene. Face data is used for control of an exposure parameter for image capturing or generation of image data processed by relating color balance to the presence of faces, or stored on a storage medium along with the image data.

摘要： PROBLEM TO BE SOLVED: To provide a method for embedding digital image into three- dimensional images from a scannerless range imaging system in a manner that allows exact recovery of its associated images. SOLUTION: The range imaging system captures (a) a plurality of phase images of reflected modulated illumination, wherein each image incorporates a phase delay term corresponding to the distance of objects in the scene from the range imaging system, together with a phase offset term unique for each image, and (b) at least one intensity image of reflected unmodulated illumination, and then generates an image bundle of associated images including the plurality of phase images and the intensity image. Meta-data are embedded into the image bundle by a) forming a digital message from the meta-data, b) converting the digital message to embedded data, and c) adding the embedded data to each phase image in the image bundle, pixel by pixel, without changing the phase term in each of the phase images, thereby allowing exact reconstruction of range information from the phase images without having to extract the embedded data.
