摘要： A solid-state imaging device electronically images at least a portion of an image of a subject formed on a film exposure surface through a potographic optical lens. This imaging device is driven at a high speed by an imaging device driver to repeatedly perform electronic imaging of the subject image. A frame memory stores a subject image signal initially imaged by the imaging device. A two-dimensional correlating circuit executes a two-dimensional correlation arithmetic operation between the subject image signal stored in the frame memory and subject image signals sequentially imaged during a film exposure period for the subject image, thereby calculating drift between the subject images formed on the film exposure surface in the x and y directions perpendicular to an optical axis of the lens. An actuator driver drives an actuator in accordance with the detected drift in the x and y directions to move lens in the x and y directions, thereby correcting the drifts.

摘要： An object image is formed on an imaging surface through a photographing optical lens system. A first displacement detector detects a displacement associated with the photographing optical lens system within a plane perpendicular to an optical axis. A second displacement detector detects a displacement associated with the imaging surface within the plane perpendicular to the optical axis. A correct section corrects positional errors of the object image to be formed on the imaging surface by adjusting an optical, positional relationship between the photographing optical lens system and the imaging surface in accordance with displacement amounts detected by the first and second displacement detecter.

摘要： The present invention provides a multi-display device that has a plurality of projectors and constructs one image as a whole. Partial images projected on a screen from the projectors overlap to have the edges thereof superposed on edges of adjoining partial images in shared fields on the screen. A sheet interceptor intercepts part of light to be projected on a shared field so that the luminance level in the shared field will agree with the luminance levels in the other fields except the shared fields. An interceptor portion of the sheet interceptor, which intercepts light from the right-hand side of a range on the screen within which a partial image is projected, can be displaced horizontally relative to an interceptor portion thereof that intercepts light from the left-hand side thereof. Likewise, an interceptor portion of the sheet interceptor that intercepts light from the upper side of the projected range can be displaced vertically relative to an interceptor portion thereof that intercepts light from the lower side thereof.

摘要： An image classification apparatus includes an image input device for inputting image data. A filing device stores the input image data and performs a read, retrieval, or edit operation on the data in accordance with a predetermined instruction. A normalizing unit corrects variations in various image input conditions or variations in image input devices to make the input conditions in execution agree with those in learning. A feature extracting unit extracts a feature amount effective for classification. A classification determination unit performs a classification determination operation on the basis of the feature amount obtained by the feature extracting unit. A display unit synthesizes a result of the classification determination operation with the input image, and displays the synthesized result. A learning control unit controls the feature extracting unit and the classification determination unit on the basis of the predetermined learning data. Accordingly, the classification apparatus classifies a portion of the input image which is difficult to extract by binarization or three-dimensional display alone, and displays the classified portion in an easily recognizable visual form.

摘要： In the exposure control circuit of an image input device according to the present invention, the rays of light from the subject pass through a diaphragm adjusting the amount of light and undergoes photoelectric conversion at a CCD imaging element. The image signal read from the CCD imaging element is accumulated more than once at an accumulating circuit. The luminance of the subject is detected at a luminance detector. Based on the detected luminance, a condition setting circuit sets the amount of incident light, exposure time, and the number of additions to suitable values. With those suitable settings, the amount of light through the diaphragm, the exposure time of the CCD imaging element, and the number of accumulations by the accumulating circuit are controlled so as to enable the subject to be photographed under the best condition.
