CONFERENCE PROCEEDINGS FREE ACCESSEastman Kodak Company introduced its first digital camera system (DCS) for the proffesional market in 1991. This system uses a 1.3 million pixel CCD in a Nikon F3 camera body. The digital electronics was tethered through a cable to the camera, which made it difficult to maneuver. Since then, we have made significant improvements in our digital camera systems up to the present DCS500 and 600 series cameras. In this paper, the requirements in the proffesional market are described and how Eastman Kodak developed the architecture to fulfill those requirements is discussed.View full abstractDownload PDF (711K) -

CONFERENCE PROCEEDINGS FREE ACCESSIn this paper, we discuss a new pixel concealment method for digital camera, and explain the method's validity by computer simulation. Our proposed pixel concealment method has turned its attention to that there is correlation on pattern between the primary colors. As the result of simulation, The better concealable image than the method by horizontal additivity average could get it.View full abstractDownload PDF (888K) -

CONFERENCE PROCEEDINGS FREE ACCESSOutput characteristics of two-dimensional solid-state detector for charged particles has been analyzed by ion irradiation with keV level energy. The detector was designed by CMOS rule and constructed as stacked CMOS-device[1]. The detector was operated under nondestructive readout mode due to correction of fixed pattern noises among pixels and reset noise of a pixel. The output signals of a pixel correlated linearly with incoming ions over the range of four orders of magnitude. Non-linear effects of the output is about 10% over the whole dynamic range of a pixel. The dominant effects of the non-linear components are reset voltage drop down by overlap capacitance. After correction of the drop down effect the nonlinearity reduced to percent level, the percent level nonlinearity was due to voltage dependence of pixel capacitance with ion irradiation.View full abstractDownload PDF (782K) -

CONFERENCE PROCEEDINGS FREE ACCESSA vision chip employing pulse width modulation(PWM) circuitry in each pixel is designed and fabricated. The neighboring pixels are interconnected with active resistors to diffuse noise, which is effective to decrease fixed pattern noise from 1% to 0.2%. By using this PWM technique it is demonstrated that histogram equalization and A/D conversion can be simultaneously realized during accumulation period. A comparator, which is used for the PWM operation, consists of one capacitor and three transistors and has A/D conversion of 7-bit precision in 2 msec. 1.2μm CMOS 2-poly 2-metal process is used to fabricate the chip, which has 16 × 16 pixels with the pixel size of 158μm × 103μm. The power consumption is 300μW per pixel in the processing speed of 500 frames per second.View full abstractDownload PDF (509K) -

CONFERENCE PROCEEDINGS FREE ACCESSA highly accurate multispectral camera and the application software have been developed as a suitable system to capture digital images of the artworks stored in galleries and museums. Instead of recording color data in the conventional three RGB primary colors, the newly developed camera and the software carry out a pixel-wise estimation of spectral reflectance, the color data specific to the object, between the wavelength range of 380 [nm]and 780 [nm] to enable the practical multispectral imaging. In order to realize the multispectral imaging, the dynamic range of the camera is set to 14 bits or over and the output bits to 14 bits so as to allow capturing even when the difference in light quantity between the each channel is large. Further, a small-size rotary color filter was simultaneously developed to keep the camera to a practical size. This camera can apply extended RGB color space to capturing system.View full abstractDownload PDF (961K) -
