摘要： A single-exposure high dynamic range (HDR) image sensor includes a first photodiode and a second photodiode, with a smaller full-well capacity than the first photodiode, disposed in a semiconductor material. The image sensor also includes a first floating diffusion disposed in the semiconductor material and a first transfer gate coupled to the first photodiode to transfer first image charge accumulated in the first photodiode into the first floating diffusion. A second floating diffusion is disposed in the semiconductor material and a second transfer gate is coupled to the second photodiode to transfer second image charge accumulated in the second photodiode into the second floating diffusion. An attenuation layer is disposed between the second photodiode and image light directed towards the single-exposure HDR image sensor to block a portion of the image light from reaching the second photodiode.

摘要： An image sensor includes a substrate, a first set of sensor pixels formed on the substrate, and a second set of sensor pixels formed on the substrate. The sensor pixels of the first set are arranged in rows and columns and are configured to detect light within a first range of wavelengths (e.g., white light). The sensor pixels of the second set are arranged in rows and columns and are each configured to detect light within one of a set of ranges of wavelengths (e.g., red, green, and blue). Each range of wavelengths of the set of ranges of wavelengths is a subrange of said first range of wavelengths, and each pixel of the second set of pixels is smaller than each pixel of the first set of pixels.

摘要： An example imaging system includes a plurality of pixel circuits each having a photodiode, a biasing circuit and a charge-to-voltage converter. The photodiode is configured to generate charges in response to light or radiation. The biasing circuit includes an operational amplifier having an input signal port for receiving a bias reference signal which controls a bias current flowing through an internal circuit of the operational amplifier. The charge-to-voltage converter is configured to accumulate the charges drained by the biasing circuit and convert the accumulated charges into a corresponding output voltage.

摘要： In an imaging element 28, a first light detecting layer 12 includes organic photoelectric conversion films 38a and 38b oriented in a prescribed axial direction so that it detects a polarized component of incident light which is directed parallel to the orientation axis. The first light detecting layer 12 also has an organic photoelectric conversion film oriented in another axial direction which is arranged in a prescribed pattern on a two-dimensional plane. A second light detecting layer 16 disposed under the first light detecting layer 12 includes photoelectric conversion elements 54a and 54b and detects a polarized component which has passed through the first light detecting layer 12 and which is directed perpendicularly to the orientation axis of the organic photoelectric conversion films 38a and 38b.

摘要： The present disclosure generally relates to HDR imaging techniques, and more specifically to HDR imaging techniques for use when a scene is moving. For time delay integration, the same scene location is repeatedly imaged on sequential rows, allowing for different gain values and/or exposure times to be utilized in different rows. The present disclosure utilizes a static or dynamic selection of gain values and/or exposure times on each row to enable stitching of the rows for high dynamic range.

摘要： A process is provided for providing high contrast motion picture imagery. The camera system includes a physical architecture that enables multiple sensors to simultaneously acquire a visual scene without parallax or dissimilar exposures. The system architecture enables current off the shelf components to be used to develop the architecture or a specific sensor array to be developed. The architecture includes optical components that split an incident light ray into multiple beams of varying intensity. Each respective split light ray is then attenuated further with neutral density filters for the wavelengths to be observed before the light ray impacts the respective pixel sights. A process has been developed to use the camera system architecture to stochastically recombine the acquired energy and estimate what the original energy was before attenuation. The process involves the development of an optimal non recursive weighting function that can be used and constructed into a lookup table. The weighting function is used to minimize the error associated with symmetrically distributed error sources. A second filtering routine then takes place to remove the nonsymmetrical sources of error such as intraocular flare. This is accomplished by estimating the symmetric errors prior to acquisition and detecting when a sensors radiant exitance estimate does not fall within this symmetrical error bounds. The final reconstructed HDR image is formed once a pool of cameras is determined and a weighting average of the viable guesses is used to estimate the actual scene radiant exitance, or in a non-unitary sense, a photometric radiance. The HDR image can be saved as a high bit depth image or tone-mapped either by the method introduced or by other means and stored to memory via convention 8-bit encoding methods for storage.
