ABSTRACT:
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.
