    • A solid-state imaging device is provided with a pixel array section wherein pixels which detect physical quantities are two-dimensionally arranged in matrix. In the solid-state imaging device, pixel signals of a plurality of systems having different sensitivities are read by analog from the pixel array section. When the gain setting of the analog pixel signal is lower than a prescribed gain, the pixel signals of the systems are amplified with each basic amplification factor, and when the gain setting is at the prescribed gain or higher, a pixel signal of at least one system having high sensitivity among the systems is amplified with a plurality of amplification factors including an amplification factor higher than the basic amplification factor of the system having the high sensitivity. To obtain the signals of the systems having different sensitivities and achieve a wide dynamic range, information loss due to being out of an AD conversion input range is eliminated when an analog gain is increased, and an image with excellent S/N is obtained. ® KIPO & WIPO 2009

    • A method of adjusting a resolution for digital data is provided to increase the resolution of the digital data in a restricted section by applying a neural network scheme on the digital data. A range of a digital value, which is to be converted, is determined. A range of a digital input value is determined corresponding to the digital value. A predetermined resolution is determined by the range of the digital value and the range of the digital input value. A relation between the input data and the output data is determined based on a neural network algorithm according to the determined resolution. The resolution has a relation of 1 by 1 or N by N. The neural network algorithm uses a multilayered perception structure.
