SOLID-STATE IMAGE CAPTURING APPARATUS AND ELECTRONIC DEVICE
The present technology relates to a solid-state image capturing apparatus and an electronic device that can acquire a normal image and a narrow band image at the same time. The solid-state image capturing apparatus includes a plurality of substrates laminated in two or more layers, and two or more substrates of the plurality of substrates have pixels that perform photoelectric conversion. At least one substrate of the substrates having the pixels is a visible light sensor that receives visible light, and at least another substrate of the substrates having the pixels is a narrow band light sensor that includes narrow band filters being optical filters permeating light in a narrow wavelength band, and receives narrow band light in the narrow band.
SOLID-STATE IMAGE SENSOR, IMAGING DEVICE, AND ELECTRONIC DEVICE
The present technology relates to a solid-state image sensor, an imaging device, and an electronic device capable of switching FD conversion efficiency in all pixels of a solid-state image sensor. A photodiode performs photoelectric conversion on incident light. A floating diffusion (FD) stores charge obtained by the photodiode. FD2, which is a second FD to which the capacity of an additional capacitor MIM is added, adds the capacity to the FD. The additional capacitor MIM is constituted by a first electrode formed by a wiring layer and a second electrode formed by a metallic light blocking film provided on a surface of a substrate on which the photodiode is formed. Switching between the FD and FD+FD2 allows switching of the FD conversion efficiency. The present technology is applicable to a CMOS image sensor.
APPARATUS AND METHOD FOR GENERATING LOCAL BINARY PATTERNS (LBPS)
Techniques for direct local binary pattern (LBP) generation are presented. An image sensor for LBP generation includes a variable reference signal generator and a sensor pixel array that can generate events based on optical signals on the sensor pixel array and a reference level from the variable reference signal generator. The image sensor also includes an address encoder that can encode the addresses of the sensor pixels that generate events, and a binary image generator that can create a binary image based on the addresses of the sensor pixels that generate the events at the reference level. The image sensor may also include a local binary pattern generator configured to determine local binary pattern labels for image pixels whose binary value changes from a first binary image at a first reference level to a subsequent second binary image at a next reference level.
Transducer measurement
A transducer such as a translinear proportional-to-absolute-temperature sensor uses two amplifiers, where each amplifier is used in a variety of modes. The first amplifier generates a measurement voltage though feedback in an analog circuit. The second amplifier samples and integrates the measurement in a switched-capacitor mode, and the output is stored on a capacitor. Then the first amplifier is set to measure its offset. The offset is sampled and integrated by the second amplifier, and the output is stored on a second capacitor. Then the first and second amplifiers are set to buffer the voltages stored on the capacitors. The measurement can then be offset-adjusted by digital or analog means. The adjusted measurement is then available to be used for calibration of, e.g., an image sensor. Other transducers, such as pressure sensors, strain sensors, gyroscopes, magnetometers, accelerometers, and xyz positioning sensors may employ the same dual amplifier approach.

Flexible digital ureteroscope
The present invention discloses a flexible digital ureteroscope that is at least partially disposable. The ureteroscope comprises a single-use catheter and a handle. The catheter comprises a distal end, a bend portion, and a proximal portion. The distal end has a rigid or semi-rigid shell that houses a set of micro lenses, an image sensor microchip, and a plurality of LED light sources. A working channel extends along the entire catheter and is coupled to a working channel port on the handle to receive various medical devices and irrigation lines during an endoscopic procedure.

The rigid or semi-rigid shell of the distal end is made of a mix of polymer composite material with graphene nano-filler for enhancing thermal dissipation. The handle may be a single-use handle or a reusable handle. In case the handle is a reusable handle, it includes a battery module and a wireless communication module for communicating with a host machine wirelessly. In case the handle is a single-use handle, to reduce cost, the handle does not include a battery module and/or a wireless communication module. Rather, the single-use handle includes a host interface for receiving power from the host machine and transmits image data to the host machine.
