摘要： A nightvision system includes an underlying device that provides output light in a first spectrum. A transparent optical device transmits light in the first spectrum from the underlying device through the transparent optical device. The transparent optical device includes an active area of a semiconductor chip. The active area includes active elements that cause the underlying device to detect light from the underlying device and transparent regions formed in the active area which are transparent to the light in the first spectrum to allow light in the first spectrum to pass through from the underlying device to a user. An image processor processes brightness maps produced using light detected by the first plurality of active elements. An illuminator coupled to the image processor inputs light into the underlying device based on image processing performed by the image processor.

摘要： Lighting conditions affect quality of images being captured. In traditional systems, illuminators (light sources) are used to illuminate the objects without considering illumination levels at different zones/sides of an object being photographed. As a result, all illuminators may run at maximum capacity, resulting in wastage of power and compromising efficiency of the system. The disclosure herein generally relates to illumination of objects, and, more particularly, to a method and system for adaptive illumination of objects. The system determines illumination at different zones of the object, and further identifies zones that are not illuminated properly in comparison with a threshold of illumination. Further the system controls intensity of only the illuminators which are responsible for illumination of the zones in which measured illumination is below a threshold of illumination, and increases the intensity by a value determined based on difference between measured illumination and the threshold of illumination, for each zone.

摘要： An electronic device comprises: an image sensor; an input unit used for inputting an instruction that accompanies switching of an actuation method of the image sensor; and a controller that switches the actuation method of the image sensor using either of a first switching method and a second switching method based on a predetermined condition according to an input of the instruction. In the first switching method, the actuation method is switched via a standby state of the image sensor according to the input of the instruction, and in the second switching method, the actuation method is switched at a timing of a start of a next frame immediately after the input of the instruction while actuating the image sensor at a predetermined frame rate.

摘要： A method for enhancing an image and an image enhancement device are described. The method for enhancing an image including: capturing an initial image including a plurality of pixels, and performing a pixel-by-pixel dehazing operation for each of the plurality of pixels. The performing including: generating, for each of the plurality of pixels, a value for a blended gray image based on color channels of the pixel, generating, for each of the plurality of pixels, a value for a transmission map based on the blended gray image, and generating, for each of the plurality of pixels, output color channels for a processed image based on the value for the transmission map, the processed image being an enhancement of the initial image.

摘要： An image sensing system includes an image sensor, a sensing controller, an additional unit, and a sensing parameter calculator. The image sensor includes a plurality of unit pixels and configured to generate raw image data indicative an image of an object from pixel signals from the plurality of unit pixels. The sensing controller is configured to control, based on a sensing parameter, a sensing condition of the image sensor for each set of the unit pixels. The parameter addition circuit is configured to obtain a parameter added data by adding the sensing parameter and the raw image data. The sensing parameter calculator is configured to calculate a distribution of pixel values for each set of the unit pixels, calculate an updated sensing parameter based on the distribution of pixel values, and transmit the updated sensing parameter to the sensing controller and the parameter addition circuit.

摘要： A system and method that provides adaptive IR illumination for a camera. In some implementations, IR illumination adapts to the objects in a scene being monitored and IR illumination adaptation may be implemented in conjunction with automatic exposure and other exposure adjustment methods. Some implementations include: illuminating a scene using a first IR illumination power; capturing a first image of the scene with a camera; and determining whether a first region of the first image is underexposed or overexposed. When the first region is underexposed, the scene is illuminated at a second power level greater than the first illumination power and a second image is captured. When the first region is overexposed, the scene is illuminated at a third power level that is less than the first illumination power and a third image is captured. The operations are repeated until scene illumination is satisfactory.
