For simplified, less computationally intensive, image recording of different spectral signal components using a plurality of color channels of a single image sensor, a targeted adjustment of a sensitivity of at least one of the color channels in relation to another one of the color channels of the image sensor is provided for a spectral separation of this reduced or adjusted color channel from the other color channel so that at least one certain spectral range (i.e., in particular a part of a first spectral range captured using the other color channel) is no longer detectable using the color channel that has been adjusted in terms of its sensitivity. This adjusted color channel becomes spectrally blind in the spectral range and can consequently spectrally selectively detect a further spectral range (specifically a second spectral range deviating from the first spectral range). The second spectral range may include a fluorescence wavelength.

Color mixing between pixels of different colors is suppressed. A solid-state imaging device includes: a semiconductor layer including a plurality of photoelectric conversion sections partitioned by an isolation region; a shared on-chip lens arranged on a light incident surface side of the semiconductor layer, the shared on-chip lens being shared by the photoelectric conversion sections adjacent to each other with the isolation region interposed between the photoelectric conversion sections, and having a condensing point positioned in the isolation region; and a concave portion provided in an upper portion of the photoelectric conversion sections that share the shared on-chip lens on the light incident surface of the semiconductor layer.

Provided are a first photoelectric conversion unit, a second photoelectric conversion unit having a smaller electric charge amount to be converted per unit time than the first photoelectric conversion unit, a charge accumulation unit that accumulates an electric charge generated by the second photoelectric conversion unit, a charge voltage conversion unit, a first transfer gate unit that transfers an electric charge from the first photoelectric conversion unit to the charge voltage conversion unit, a second transfer gate unit that couples potentials of the charge voltage conversion unit and the charge accumulation unit, a third transfer gate unit that transfers an electric charge from the second photoelectric conversion unit to the charge accumulation unit, an overflow path formed under a gate electrode of the third transfer gate unit and transfers an electric charge overflowing from the second photoelectric conversion unit to the charge accumulation unit, and a light reducing unit that reduces light to enter the second photoelectric conversion unit.

Image-capturing device includes: an image sensor that includes a first pixel and a second pixel, each having a filter unit that can be switched to a light-shielding state in which light is blocked or to a transmissive state in which light is transmitted, a photoelectric conversion unit that generates an electric charge through photoelectric conversion of light transmitted through the filter unit and an output unit that outputs a signal based upon electric charge generated at the photoelectric conversion unit, and; a correction unit that corrects a signal output from the output unit of the first pixel while the filter unit of the first pixel is in a transmissive state, based upon a signal output from the output unit of the first pixel with the filter unit of the first pixel set in a light-shielding state and with the filter unit of the second pixel set in a transmissive state.

An image adjustment apparatus includes a receiver which is configured to receive a first input image of an object which is time-synchronously captured and a second input image in which a motion event of the object is sensed time-asynchronously, and an adjuster which is configured to adjust the first input image and the second input image.

The present disclosure relates to a solid-state imaging device and an electronic device that can be provided with phase difference pixels with a lower degree of difficulty in manufacturing.

Provided is a solid-state imaging device including a pixel array unit in which a plurality of pixels is two-dimensionally arrayed, in which the pixel array unit has an array pattern in which a plurality of pixel groups each including neighboring pixels of an identical color is regularly arrayed, and among the plurality of pixel groups arrayed in the array pattern, pixels configuring a light-shielded pixel group are shielded in an identical direction side from light, the light-shielded pixel group being a pixel group including pixels each being shielded in a part of a light incident side from the light. The present technology can be applied to, for example, a CMOS image sensor including pixels for phase difference detection.

An imaging apparatus includes an imaging element including photodiode divided pixels, and a control unit. The control unit performs control to execute first readout in which an addition value of a first pixel and a second pixel constituting a photodiode divided pixel is read out as a pixel value constituting an image and second readout of performing readout in which a value of the first pixel and a value of the second pixel used for phase difference detection can be obtained from a photodiode divided pixel that is not a readout target in the first readout. In this case, the first readout is performed after performing the second readout in one vertical period.

Methods and systems are disclosed using camera devices for deep channel and Convolutional Neural Network (CNN) images and formats. In one example, image values are captured by a color sensor array in an image capturing device or camera. The image values provide color channel data. The captured image values by the color sensor array are input to a CNN having at least one CNN layer. The CNN provides CNN channel data for each layer. The color channel data and CNN channel data is to form a deep channel image that stored in a memory. In another example, image values are captured by sensor array. The captured image values by the sensor array are input a CNN having a first CNN layer. An output is generated at the first CNN layer using the captured image values by the color sensor array. The output of the first CNN layer is stored as a feature map of the captured image.

An image acquisition apparatus includes: a multispectral image sensor configured to acquire images in at least four channels based on a second wavelength band of about 10 nm to about 1,000 nm; and a processor configured to estimate illumination information of the images by inputting the images of at least four channels to a deep learning network trained in advance, and convert colors of the acquired images using the estimated illumination information.
