摘要:
An encoding and decoding apparatus and method which has the primary benefit over the prior art of not requiring storage of the nonlinear sequence of numbers representative of the quantization characteristics. The hardware required for quantization is reduced and inverse quantization may be achieved using shifting operations and a multiplier of up to half the scale compared to conventional encoding/decoding methods and encoding/decoding apparatus.

A color classification system and method for classifying, judging and/or identifying objects by color. An optical system utilizes light from an object to form an image on an imaging device. A plurality of optical band-pass filters each having a different pass band are provided between the object and the imaging device. The optical band-pass filters include a plurality of measurement filters for use in measuring a color of the object and a test filter for use in judging which one of the measurement filters should be applied to the object. A changeover section changes between the optical band-pass filters. A computing circuit performs at least one of a color classification and a color judgment based on a spectral characteristic of the imaged object through a statistical approach, and a control section causes the changeover section to select an effective one of the measurement filters based on a judgment by the computing circuit of a result sensed by the test filter. The plurality of optical band-pass filters are arranged in a plurality of filter sets each of which has at least one filter, and the changeover section includes a filter changeover mechanism for changing between the optical band-pass filters in one of the filter sets, and a filter-set changeover mechanism for changing between the plurality of filter sets.

The horizontal address and the vertical address of a picture image are arrayed at the lower and upper order sides, respectively, and allocated to a lower order side column address and an upper order side column address of the synchronous DRAM employed as a picture memory, respectively. A bank switching address is allocated between the upper most bit of the horizontal address and the lower most bit of the row address to enable data to be read continuously to achieve high-speed accessing and improve the utilization efficiency of the data bus.

摘要:
An input section receives an image signal including signals related to colors to output at least a luminance signal component of the image signal. A compressing section compresses the dynamic range of the luminance signal component from the input section. A setting section obtains a compression coefficient from a relationship between the luminance signal component whose dynamic range is compressed by the compressing section and the luminance signal component from the input section. An operating section executes an operation for compressing dynamic ranges of the signals related to colors included in the image signal in accordance with the compression coefficient obtained by the setting section. A correcting section substantially corrects the color saturation of the signals related to a color included in the image signal while preserving the luminance of the image signal such that the color saturation is more intensively suppressed as the luminance becomes lower.

The present invention provides a simple, low-cost color classification apparatus having a high resistance to mechanical vibrations and capable of properly performing color classification even if a light source is not specified and its spectrum changes. A color classification apparatus of the present invention is further including an image pickup means for picking up a spectrum of light reflected by a target object, a plurality of bandpass filters having different bands and arranged between the target object and the image pickup means, and a classifying means for calculating a classification spectrum for classification using a statistic technique from a spectrum of light reflected by the target object and picked up by the image pickup means, and classifying the target object using the classification spectrum.
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.

A top entry ball valve is proposed which has a valve body formed with a valve chamber, a valve mounted in the valve chamber, a seat ring at the low-pressure side, and a seat ring assembly having another seat ring, a belleville spring and a seat ring holder at the high-pressure side. The seat ring assembly can be easily mounted into and removed out of the valve chamber by use of a clamp while comprising the belleville spring. The clamp comprises a pair of clamping pieces fastened together with a bolt.
