    摘要： A fishfinder is provided for identifying with high precision a single fish under the ship and for measuring the length of the fish precisely. An operator of the fishfinder is assisted to grasp the depth and the length of the fish. A fishfinder transmits an ultrasound pulse having a high carrier frequency and an ultrasound pulse having a low carrier frequency by means of a pulse transmission and reception device at predetermined time intervals. A single fish echo is determined and tracked for a plurality of transmission intervals of ultrasound pulses emitted into the water. A target strength of single fish is measured based on the signal strength of a low carrier frequency echo signal from the single fish. The length of the fish is measured based on the target strength. A fish mark is displayed on the screen of an indicator, with the size of the fish mark depending on the fish length.

    摘要： An image correction method can perform adaptive correction processing to a taken image by a simple construction in a short time, and includes the steps of: computing window region local difference values for a plurality of neighboring pixels, each of the window region local difference values being a difference value between image data of a notice pixel (33a) in a difference value determination region (32) formed of a whole or a part of a screen area of an input image (31) and image data of a neighboring pixel in a window region (33) set around the notice pixel (33a), thereby determining a maximum local difference value which is a maximum value of the window region local difference values in each window region; determining a threshold value reflecting a characteristic of the input image on the basis of the maximum local difference value; producing adaptive filter coefficients for respective pixels of the input image by using the threshold value; and performing filter processing of the input image by using the adaptive filter coefficients.

    摘要： A signal phase adjustment circuit to set an optimum phase by adjusting the difference in delay times between signal lines even when the distribution of the amount of phase modification that can be received normally is divided into a plurality of continuous regions. The amount of phase modification of the transmitted signal is allowed to fluctuate during one cycle of the operational frequency of the circuit. Determination of whether or not the reception signal during this interval can be received is continued, and the distribution of amount of phase modification that can be normally received is detected. The detected amount of phase modification defines continuous regions, and an optimum phase region is specified by selecting a region having a width of a specified value or more or the region having the greatest width. The optimum amount of sampling phase modification is determined from the upper and lower limit values of this region.
