摘要： An image pick-up section generates an electronic still image signal. An A/D conversion section converts the electronic still image signal generated by the image pick-up section into a digital signal. A data compressing section causes variable-length encoding data compression to the digital signal obtained by the A/D conversion section so as to obtain compressed image data. A recording section records the image data compressed by the data compressing section in a recording medium having a predetermined recording capacity. A calculating section calculates an estimated count of electronic still images which can be recorded in the recording medium in accordance with quantitative data associated with the image data recorded in the recording medium by the recording section and quantitative data associated with the recording capacity of the recording medium. An indicating section indicates the estimated count of the recordable electronic still images calculated by the calculating section.

摘要： A noise suppressor is provided for an electronic endoscope which incorporates a diathermic cutter or an ultrasonic diagnosis system. The electronic endoscope utilizes a solid-state camera, and in order to prevent noises from being superimposed upon the signal fed to an image display, a transmission line which transmits a high frequency current to the diathermic cutter or a transmission line which transmits an ultrasonic signal to or receives an ultrasonic signal from an ultrasonic probe is shielded by a conductor member. In particular, for a transmission line which conveys the high frequency current, impedance regulating means is connected therewith in order to prevent the high frequency current from leaking through a distributed capacitance between the transmission line and the conductor member. Alternatively, a narrow bandpass filter may be provided which limits the frequency band of the high frequency current. A coaxial cable may be used in which both the transmission line and the conductor member are formed of conductive rubber.
