A solid-state imaging device includes a layout in which one sharing unit includes an array of photodiodes of 2 pixels by 4n pixels (where, n is a positive integer), respectively, in horizontal and vertical directions.

An image sensor is provided which includes a first group of pixels including a first color filter passing light having a first wavelength range, a second group of pixels including a second color filter passing light having a second wavelength range, and a third group of pixels including a third color filter passing light having a third wavelength range. The first wavelength range is longer than the second wavelength range, and the second wavelength range is longer than the third wavelength range. A second pixel in the second group of pixels or a third pixel in the third group of pixels includes a plurality of photoelectric conversion devices, and a first pixel of the first group of pixels includes a single photoelectric conversion device.

Embodiments described herein can address these and other issues by providing a CV image sensor that has a repeating pattern of two pairs of color-opponent color sensors and a luminance sensor to provide a high amount of functionality while maintaining relatively low power requirements. By using color opponency, embodiments can sidestep the need for processor-intensive color conversions required of other color sensors. Embodiments may optionally provide for surface area optimization, hyperspectral sensitivity, low-light optimization, neuromorphic light sensing, and more.

A solid-state imaging device includes a second image sensor having an organic photoelectric conversion film transmitting a specific light, and a first image sensor which is stacked in layers on a same semiconductor substrate as that of the second image sensor and which receives the specific light having transmitted the second image sensor, in which a pixel for focus detection is provided in the second image sensor or the first image sensor. Therefore, an AF method can be realized independently of a pixel for imaging.

The present disclosure relates to a solid-state imaging device that can achieve a high S/N ratio at a high sensitivity level without any decrease in resolution, and to an electronic apparatus. In the upper layer, the respective pixels of a photoelectric conversion unit that absorbs light of a first wavelength are tilted at approximately 45 degrees with respect to a square pixel array, and are two-dimensionally arranged in horizontal directions and vertical directions in an oblique array. The respective pixels of a photoelectric conversion unit that is sensitive to light of a second or third wavelength are arranged under the first photoelectric conversion unit. That is, pixels that are 2 times as large in size (twice as large in area) and are rotated 45 degrees are arranged in an oblique array. The present disclosure can be applied to solid-state imaging devices that are used in imaging apparatuses, for example.

An endoscopic video system and method using a camera with a single color image sensor, for example a CCD color image sensor, for fluorescence and color imaging and for simultaneously displaying the images acquired in these imaging modes at video rates in real time is disclosed. The tissue under investigation is illuminated continuously with fluorescence excitation light and is further illuminated periodically using visible light outside of the fluorescence excitation wavelength range. The illumination sources may be conventional lamps using filters and shutters, or may include light-emitting diodes mounted at the distal tip of the endoscope.

A solid-state image pickup apparatus includes a pixel array unit in which image signal generation pixels for generating analog image signals in response to light irradiated thereupon and correction signal generation pixels for generating analog correction signals for correcting the image signals are arranged in a matrix pattern. A conversion unit performs first conversion that is conversion from the analog image signals generated by the image signal generation pixels arranged in a row in the matrix pattern into digital image signals. The conversion unit further performs second conversion, which is conversion performed at substantially the same time with the first conversion, from the analog correction signals generated by the correction signal generation pixels arranged in a plurality of rows in the matrix pattern into digital correction signals. A correction unit performs correction of the digital image signals with the digital correction signals generated in the plurality of rows.
