    • An image retrieval method includes reading from a first database a first image group mapped to an object as a retrieval target, and extracting an image feature quantity of a plurality of images of the first image group. A second image group mapped to an object as a search key is read from a second database and an image feature quantity of a plurality of images of the second image group is extracted. Similarity is determined between the first image group and the second image group, based on the image feature quantity of the plurality of images of the first image group and the image feature quantity of the plurality of images of the second image group. On an output device, as retrieval results, the plurality of images of the first image group are displayed in order of similarity of the object as the retrieval target based on determined similarity.

    • Herein disclosed is a method of processing a malfunction of an accelerator pedal sensor of an automobile. An output voltage is outputted according to changes in a resistance depending upon depression of an accelerator pedal. A malfunction of the accelerator pedal sensor is shot to process and determine an acceleration value for controlling the run of the automobile in accordance with said output voltage. The acceleration value is set at a predetermined value in accordance with the malfunction of either of an idle switch for generating a signal indicating the idle position of the accelerator pedal and a wide-open switch for generating a signal indicating the wide open position of the accelerator pedal when the malfunction of the accelerator pedal sensor is judged. This judgement is conducted by detecting a plurality of times that said output voltage is outside of the predetermined voltage range. The acceleration value is set at a predetermined minimum value, when the idle switch is in a normal state, at a predetermined relatively high value, when the wide-open switch is in a normal state, and at a predetermined relative low value when both the two switches are troubled.

    • Herein disclosed is a signal processing system for a motor vehicle with high responsiveness to the will of a driver. The output voltage of an acceleration sensor using a potentiometer is converted into a digital value by an analog-digital converter. The nonlinearity of the output voltage is corrected by polynominally calculating the digital value. This digital value is controlled by a central processing unit which processes the digital value to generate an acceleration signal having a linear relationship to the changes in the resistance of the potentiometer during actuation of an accelerator. The central processing unit further includes a memory for storing the acceleration signal at an idling position to determine a calibrated acceleration signal using a ratio of an actual acceleration signal obtained from the accelerator pedal to the stored value thereof.
    • 这里公开了一种用于机动车辆的信号处理系统,其对驾驶员的意愿具有高响应性。 使用电位计的加速度传感器的输出电压由模拟数字转换器转换为数字值。 通过多项式计算数字值来校正输出电压的非线性。 该数字值由中央处理单元控制,中央处理单元处理数字值以产生与加速器致动期间电位器的电阻变化呈线性关系的加速度信号。 中央处理单元还包括存储器,用于在怠速位置存储加速度信号,以使用从加速器踏板获得的实际加速度信号与其存储值的比率来确定校准加速度信号。
