    For low light level imaging application, a new image sensor superior to an ICCD (Intensified CCD) in image quality, an electron bombardment CCD tube (EB-CCD) has been developed. Electrons emitted from the photocathode are accelerated and bombard the electron sensitive CCD, and produce a lot of electron-hole pairs which is a gain of the EB-CCD. As a result of the evaluation, the electron bombardment gain of 600 and the spatial resolution of 18 (lp/mm) are obtained at the photocathode voltage of -8 (kV). Also the noise of the incorporated CCD is 13 (e RMS) at -25 degree. As it is anticipated from the result that the gain is much higher than the noise of the CCD, the single photon image can be clearly observed by the developed EB-CCD.

    This paper describes the design and the implementation of a CMOS image sensor integrating focal-plane compression using an analog 2-dimensional discrete cosine transform(2-D DCT) processor and variable-quantization-level A/D converter. The proposed focal-plane compression scheme is particulary useful for high-speed cameras and low-cost, low-power portable cameras. The PSNR of time reconstructed image using the on-sensor analog 2-D DCT circuits is 36.7dB. The power dissipation of the analog 2-D DCT circuits is about 10.8mW at 3V. The total one-chip camera system power is estimated to be about 30mW, allowing us to use for portable devices.

    On-focal-plane signal processing for current-mode active pixel sensor(APS) including fixed pattern noise (FPN) suppression and high resolution analog-to-digital conversion(ADC) is presented. An FPN suppression circuit that removes the offset current variation between pixels by using a combination of an n-type and a p-type current copier cell is described. Also, operation and performance of a current-mode second-order incremental Δ-Σ A/D converter with column parallel architecture and for high resolution and medium-slow-speed application is presented.

    This paper describes a new type of image sensors on which correlation detectors between incident lights and electronic signals are integrated as a 2-D array. This architecture is characterized by : 1) photo diodes for converting incident photons to currents, 2) one or a few external electronic signal inputs which are common to all pixels, 3) multipliers for generating products between the photo currents and the electronic signals, 4) capacitors for integrating the products and store the correlation results, and 5) CCD or MOS switching networks for scanning the correlation results as conventional video signals. Several architectures and circuits are proposed and examined. Several applications of the sensor are discussed.

    The first sample of the field emission display (FED) was reported by LETI, France, 10 years ago. Since then, various laboratories, academic institutions and companies have been proceeding the research on the FED. There were some technical information and topics regarding new types of electron source in the recent year. This paper describes the movement of the FED development and the present status of the development of the FED using the Spindt-type cathode.

    An "Address-while-Display" scheme has been developed for HDTV expression using a 3-electrode. surface-discharge AC-PDP. The scheme applies both scan and signal pulses to the panel during intervals between display pulses, requiring no additional time for panel-addressing. As a result, a light-emission duty was extended to 91%. The duty is independent of the number of scanning lines. Using the scheme, 256 gray levels with a peak white luminance of 1200 cd/m^2 was obtained.

    Dispersed of the emission period in a field causes deterioration in the motion picture quality of the sub-field PDP. To alleviate this problem, we have been developed a drive method which compresses the emission period on the DC PDP, The emission periods of each sub-fields are also divided into smaller units and optimized the arrangement. The emission patterns are controlled adaptively by signal processing. In order to assess the effectiveness of these methods we used simulations to calculate the S/N ratio for the quantity of disturbance.
