Solid-state image sensing device for endoscope and endoscope imaging apparatus

摘要

A solid-state image sensing device for endoscopes including a color mosaic filter provided on a CCD image pick-up surface and having filters arranged so that the number of G-component pixels>/=the number of B-component pixels>the number of R-component pixels, the number of CCD pixels being set at a minimum requisite level in accordance with the information-amount characteristics of the endoscopic image to be picked up. A plurality of LPFs are provided in a signal processing section providing image signal resolution in which the G-component bandwidth>/=B-component bandwidth>R-component bandwidth, thereby obtaining an image-signal resolution which is high enough to allow the endoscopic image to be displayed, with the B-component being equal to or smaller than the G-component and larger than the R-component.
