    摘要: An image data coding apparatus performs first and second coding processes. A controller outputs first and second control signals. An orthogonal transform circuit performs orthogonal transform on image data of one screen and generates an transformed output. A quantizing circuit quantizes the transformed output with a predetermined temporary first quantization width upon reception of the first control signal and generates a first quantized output, and quantizes the transformed output with an optimal second quantization width upon reception of the second control signal and generates a second quantized output. An entropy coding circuit codes the first quantized output and generates a first coded output, and codes the second quantized output and generates a second coded output. An amount-of-codes calculator calculates the amount of codes of the first coded output for each block and calculates the amount of codes of one screen based on the amount of codes for each block. An assigned-amount-of-codes determining circuit determines the amount of codes assigned to each block based on the amount of codes for each block and the amount of codes of the one screen, and the target amount of codes. A quantization width predicting circuit predicts the second quantization width based on the amount of codes of the one screen. A coding stop circuit supplies a coding stop signal to the entropy coding circuit when the amount of codes of the second coded output exceeds the assigned amount of codes.

    摘要: Recognition character candidates and their similarities for each character obtained by a character recognition section from an input character string are stored in a first recognition result memory, and recognition character candidates obtained by rotating the corresponding characters through 180 degrees and their similarities are stored in a second recognition result memory. Address pointers for accessing the first and second recognition result memories are stored in an address pointer memory. The first recognition result memory is accessed in accordance with the address pointers read out from the address pointer memory in an ascending order, and the second recognition result memory is accessed in accordance with the address pointers read out from the address pointer memory in a descending order. Coincidences between recognition candidates read out from the first and second recognition result memories and character strings of dictionary words read out from a dictionary memory are computed by a coincidence computing section. A recognition result of the input character string is obtained based on the coincidences.

    摘要: A laser light flux is divided and synthesized so that its light intensity distribution is changed from a Gaussian distribution to a non-Gaussian distribution. When a laser light flux having a Gaussian distribution is irradiated onto a dividing prism, it is divided into a left part and a right part which are refracted right and left inversely from each other. When the right and left parts are incident on a synthesizing prism, they are refracted again and travel to be overlapped with each other on a recording medium. The light intensity distribution on a segment at the apex of the synthesizing prism is weaker at the central part and stronger at the peripheral part. This is because the light fluxes resulting from the division are inverted in their position so that the central part of the Gaussian distribution is separated left and right while the peripheral part with a weaker light intensity is centered.

    摘要: An ultrasonic imaging apparatus comprises first and second ultrasonic transducers and a driver circuit for alternately driving the first and second ultrasonic transducers to transmit ultrasonic beams in directions crossing at a given target. A receiver fetches from the echo signals of the first and second ultrasonic transducers echo components corresponding to echoes reflected in the same direction as the ultrasonic transmission direction and at a predetermined angle with respect to the target. An arithmetic logic circuit processes the echo signal components to obtain an angular dependency of scattering. A monitor displays the information representing the angular dependency of scattering.

    摘要: The echo signals from ultrasonic transducer elements are filtered by a plurality of prestage band pass filters having different central frequencies and frequency pass bands. The filtered echo signals from those band pass filters are composed by an adder into a composite echo signal. This composite echo signal from the adder is filtered by a variable band pass filter whose central frequency is shifted and whose frequency band is fixed, whereby the echo signal components passed through the prestage band pass filters are extracted sequentially. The echo signal components from the variable band pass filter are converted by a signal processing circuit into a tomographic signal, which is displayed as a tomographic image by a display.
