Image sensing device for acquiring a light field image
An image sensing device includes a pixel array configured to include a first pixel group and a second pixel group that are contiguous to each other, each of the first pixel group and second pixel group including a plurality of imaging pixels to convert light into pixel signals, and a light field lens array disposed over the pixel array to direct light to the imaging pixels and configured as a moveable structure that is operable to move between a first position and a second position in a horizontal direction by a predetermined distance corresponding to a width of the first pixel group or a width of the second pixel group, the light field lens array configured to include one or more lens regions each including a light field lens and one or more open regions formed without the light field lens to enable both light filed imaging and conventional imaging.
Wide dynamic range electronic image recording and reproducing system
The electronic camera has an imaging device that images a subject with subject reflectance R (%) with a dynamic range wider than that at displaying or printing to acquire image data and a recording device that converts the image data acquired by the imaging device with a predetermined function and records the converted image data and the information on the function as digital values (digit). Therefore, a printed image with an automatically or manually corrected density can be obtained at the displaying or the printing.

A photoelectric conversion device according to one embodiment includes: a first substrate including a pixel that includes a photoelectric conversion element; and a second substrate including a first control unit that includes a first signal processing unit configured to process a signal from the pixel, the second substrate being stacked together with the first substrate. The signal from the pixel is output to a second signal processing unit disposed at a position different from a position of the first signal processing unit, a path through which the signal from the pixel is output to the first signal processing unit is different from a path through which the signal from the pixel is output to the second signal processing unit, and the first control unit is configured to control the pixel on the basis of the signal processed by the first signal processing unit.
Cryostat inspection camera arrangement and method
A bung assembly for closing an opening in a turret of a cryostat has a camera housing and bung body that is mechanically dimensioned to fit the opening, and is provided with a sealing arrangement for forming a gas-tight seal between the bung body and the turret.
IMAGING ELEMENT, IMAGING APPARATUS, OPERATION METHOD OF IMAGING ELEMENT, AND PROGRAM
An imaging element includes a reading circuit that reads out pixel data obtained by imaging a subject at a first frame rate, a memory that stores the read pixel data, and an output circuit that outputs image data based on the stored pixel data at a second frame rate. The first frame rate is a frame rate higher than the second frame rate. The pixel data includes phase difference pixel data and non-phase difference pixel data different from the phase difference pixel data. The reading circuit reads out the pixel data of each of a plurality of frames in parallel within an output period defined by the second frame rate as a period in which the image data of one frame is output, and performs reading of the non-phase difference pixel data and a plurality of reading of the phase difference pixel data within the output period.
Generating an image-based identifier for a stretch wrapped loaded pallet based on images captured in association with application of stretch wrap to the loaded pallet
Methods, apparatus, systems, and computer-readable media are provided that relate to using one or more vision sensors to capture images of a loaded pallet in association with application of stretch wrap to the loaded pallet by an automated pallet wrapping machine. The images are used to generate an image-based identifier for the loaded pallet that is then used for pallet identification by mobile robots and/or other automated agents in a warehouse or other environment. In some implementations, the images are captured by the vision sensor when the pallet is in the wrapping area of the automated pallet wrapping machine and while the vision sensor and/or the pallet are rotating. In some implementations, the image-based identifier may be assigned to pallet attributes and/or a de-palletizing scheme of the loaded pallet.
Systems and methods for mitigating global event power surge in image sensors
An image sensor may include a pixel array, row control circuitry, and column readout circuitry. The row control circuitry may operate the pixel array in a global shutter mode of operation. In particular, timing control circuitry may provide global timing clock signals associated with a global photodiode reset event and a global photodiode charge transfer event to row driver circuitry providing control signals to each row in the array. Each driver circuitry may include a time delay circuit that delays the global timing clock signal by different amounts across the rows. Therefore, these global events may be offset on a per-row or per-row group basis, thereby mitigating power surges associated with global events. Further, by offsetting the global photodiode reset and charge transfer events using the same delay for a given row, the same global integration time may be preserved across different rows.
IMAGE SENSORS HAVING HIGH DYNAMIC RANGE IMAGING PIXELS
A high dynamic range imaging pixel may include a photodiode that generates charge in response to incident light. When the generated charge exceeds a first charge level, the charge may overflow through a first transistor to a first storage capacitor. When the generated charge exceeds a second charge level that is higher than the first charge level, the charge may overflow through a second transistor. The charge that overflows through the second transistor may alternately be coupled to a voltage supply and drained or transferred to a second storage capacitor for subsequent readout. Diverting more overflow charge to the voltage supply may increase the dynamic range of the pixel. The amount of charge diverted to the voltage supply may therefore be updated to control the dynamic range of the imaging pixel.
IMAGE SENSOR, IMAGING SYSTEM INCLUDING THE SAME, AND METHOD EXECUTED BY IMAGING SYSTEM
In an image sensor, an analog-to-digital conversion circuitry generates image data by sequentially performing analog-to-digital conversion processing twice or more on a pixel signal transferred from the pixel array in an operation period of one horizontal cycle, and an image signal processing circuitry receives the image data and performs digital processing on the image data. A timing controller controls the image signal processing circuitry to hold the digital processing during a plurality of holding periods that respectively correspond to portions of two or more ADC processing periods.
IMAGE SENSOR
An image sensor includes an analog-to-digital conversion circuit that receives pixel signals from column lines, respectively, and converts the pixel signals into first pixel values, respectively. Data buffer clusters correspond to enable signals transferred from a timing controller, respectively, and output second pixel values. Each of the data buffer clusters stores first pixel values, which correspond to some column lines consecutively arranged among the column lines, among the first pixel values and output stored pixel values as some second pixel values among the second pixel values in response to a corresponding enable signal. A digital processing circuit performs digital processing on the second pixel values output from the data buffer clusters.
