摘要： A method of operating an image sensing device includes applying control voltages to a pixel array in accordance with a test mode and performing an analog-to-digital conversion of a column line voltage to obtain one or more digital codes. The one or more digital codes are evaluated to detect an operating error associated with the column line and/or corresponding analog to digital converter. In response to an operating error, pixel values may be replaced or averaged with nearby pixel outputs not affected by the operating error.

摘要： A method for mapping non-uniformities of a portable image sensor having image sensor elements, each image sensor element having a coordinate. The method including the image sensor capturing images of a property from a test pattern using different image sensor elements. The non-uniformity of the image sensor can be mapped by storing the values of the property with the respective image sensor element coordinates in a look-up table.

摘要： A method for adjusting display colors, an electronic device, and a storage medium are provided. The method includes: in response to a selection operation acting on color blocks, the color blocks are filled to controls to be filled; and upon detecting that the color blocks are all filled to the controls to be filed, the display colors are adjusted on the basis of a relationship between arrangement orders and preset arrangement orders. By adjusting the display colors of the electronic device according to a test result, personalization of the display color is achieved, and the user experience is improved.

摘要： A camera module test apparatus having improved performance include a coefficient data extractor that accommodates a camera module; and a test apparatus that accommodates the camera module and tests the camera module. The coefficient data extractor includes a coefficient generator that receives an image signal output from the camera module, and generates coefficient data of a ratio of a first color image signal and a second color image signal included in the image signal; and a memory device that stores the generated coefficient data. The test apparatus includes an image generator that receives an image signal from the camera module and coefficient data from the memory device, and generates a converted pattern image signal based on the image signal and the coefficient data; and a calibration data generator that generates calibration data of the converted pattern image signal.

摘要： A method of calibrating a display system, the method comprising: displaying a test pattern including a plurality of blobs; detecting one or more base blobs in the displayed test pattern; identifying, based on the detected base blobs, patches of the test pattern, wherein each patch comprises one of the base blobs and a subset of additional blobs detected in the displayed test pattern; determining a patch location for at least one patch within the test pattern based on the subset of the additional blobs in the patch to determine a blob location for at least one detected blob; determining a calibration parameter for the display system based on the blob location and a detected attribute of the at least one detected blob; and calibrating the projector using the calibration parameter.

摘要： A vehicular test system for testing a vehicular sensing system includes a sensor support structure having a proximal end disposed at a vehicle, a distal end extending away from the vehicle, and a force providing element that provides a force to move the distal end of the sensor support structure. A vehicular sensor is disposed at the distal end of the sensor support structure. When the vehicular sensor is approaching a collision with an object, such as during testing of vehicular sensors and vehicular sensing systems, a control controls the force providing element to move the distal end of the sensor support structure and the vehicular sensor to avoid the collision.

摘要： Systems and methods for calibrating an array camera are disclosed. Systems and methods for calibrating an array camera in accordance with embodiments of this invention include the capturing of an image of a test pattern with the array camera such that each imaging component in the array camera captures an image of the test pattern. The image of the test pattern captured by a reference imaging component is then used to derive calibration information for the reference component. A corrected image of the test pattern for the reference component is then generated from the calibration information and the image of the test pattern captured by the reference imaging component. The corrected image is then used with the images captured by each of the associate imaging components associated with the reference component to generate calibration information for the associate imaging components.

摘要： An image signal processor and an image sensor including the same are disclosed. An image sensor includes a pixel array configured to convert received optical signals into electrical signals, a readout circuit configured to convert the electrical signals into image data and output the image data, and an image signal processor configured to perform deep learning-based image processing on the image data based on training data selected from among first training data and second training data based on a noise level of the image data.

摘要： An information processing apparatus simulates a measurable region of a sensor when the sensor is arranged in a measurement region to be measured, and the information processing apparatus includes: a generation unit that generates a measurement region map with environment information based on a three-dimensional model of the measurement region to be measured and the environment information that causes a change in a measurement result of the sensor; an execution unit that virtually arranges the sensor on the measurement region map with environment information generated by the generation unit, and simulates the measurable region of the sensor based on sensor information related to the measurable region of the sensor; and an output unit that outputs a result of simulation by the execution unit.
