CHARGE-COUPLED SEMICONDUCTOR DEVICE AND IMAGE SENSOR DEVICE OF HIGH INFORMATION DENSITY

摘要

In a CCD, especially in an image sensing device, the electrodes of the sensor part and the memory part can be switched between a reference level signal and clock pulse signals. As a result, the information density and hence in the image sensor device the number of image lines to be read out independently can be doubled. Thus, the resolution is improved and it is possible to record even and odd lines simultaneously (for example, for an electronic still camera).
