    • An electronic endoscope system which picks up images by colors sequentially in a field sequential method, simultaneously converts the field sequential image signals obtained thereby, and reproduces the images as color images. The electronic endoscope system sample checks at every given cycle whether an image being currently picked up is a still picture image or a moving picture image. In the electronic endoscope system, the field sequential image signals are simultaneously. Each time the currently picked-up image is found as a still image, the storage contents of the memory means are updated to the latest field sequential image signals. Due to this, the memories can always store the latest field sequential image signals with no color discrepancies, e.g. shift. If a freeze instruction is input, then the updating of the storage content of the memories is immediately inhibited, so that the latest still image signals having no color discrepancies can be obtained from the memories.
    • 电子内窥镜系统通过场顺序方法顺序地拾取图像的图像,同时转换由此获得的场顺序图像信号,并将图像再现为彩色图像。 电子内窥镜系统样品在每个给定的周期检查当前拾取的图像是静止图像图像还是运动图像图像。 在电子内窥镜系统中,场顺序图像信号是同时的。 每当当前拍摄的图像被发现为静止图像时,存储装置的存储内容被更新为最新的场顺序图像信号。 由此,存储器可以始终存储没有颜色差异的最新的场顺序图像信号,例如, 转移。 如果输入了冻结指令,则立即禁止更新存储器的存储内容,从而可以从存储器获得没有颜色差异的最新的静止图像信号。

    • An electronic endoscope, having an electronic circuitry arranged to apply output signals of a solid-state image sensor to a processor, to store sequentially obtained picture data of a subject in an image memory means after predetermined signal processing, and to read out a plural number of picture data from the image memory means to produce simultaneous video signal, while providing a still image memory means parallel with the image memory means, along with a switch means for selectively supplying the signals from the image memory means or from the still image memory means as output signals. Further, the electronic circuitry includes a noise reducer incorporating a motion detector and located on the output side of the image memory means, and a still image control means adapted to detect deviations in color signal on the basis of output signals of the motion detector of the noise reducer and to renew the data in the still image memory means each time when no color deviation is detected in the picture signals from the solid-state image sensor.
