    摘要: In an imaging apparatus capable of expanding a dynamic range image signals of different levels are read simultaneously from a solid-state element whose light-receiving surface is divided. Read 1/2 frame image signals are switched by a changeover switch circuit at intervals of a 1/2 frame time. One of two image signals of different levels supplied from the two outputs of the changeover switch circuit is delayed at a delay circuit. Further, those image signals are separated into r, g, and b components, and then undergo logarithmic conversion into image signals of multiple desired levels. The signals are digitized at an A/D converter and undergo operations at an adder, which adds while keeping their logarithmic characteristic, and at an inverse logarithmic converter. A luminance signal is obtained at a matrix circuit, and is converted into a logarithm at a logarithmic circuit. The lighting irregularity components of the resulting signal are suppressed. This signal is compressed, and the compressed signal is subtracted at a subtracter to obtain a compression coefficient, which is added to the digitized image signal from the A/D converter. Image signals of a wide dynamic range corrected at the inverse logarithmic converter are obtained for a single image at a TV rate on a real-time basis. Further, the control of exposure to the entire image and the expansion of the dynamic range are possible.

    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.
