An improved design is presented for an ISIS, In-situ Storage Image Sensor, previously proposed by the authors for a high frame rate video camera of 1,000,000 pps. CCD channels of the sensor play dual roles for signal storage in an image capturing phase and for signal transfer in a read-out phase, which minimizes unutilized spaces on the light receptive area. The transfer direction is only vertical, which simplifies the structure of the sensor and provides better quality in reproduced images. An overwriting mechanism is built in, which facilitates synchronization of cease of the image capturing phase to the occurrence of a target event. The design is improved by coupling adjacent two CCD channels and two photodiodes, which provides wider spaces to place metal wires to increase rate of charge drive.
