摘要： In an image processing method, an image processing device obtains an input image from an image sensor. Each pixel of the input image is either a type-I pixel or a type-II pixel. Each type-I pixel carries a luminance channel value and no color data, and each type-II pixel carries a single color channel value and no luminance data, wherein the single color channel value is a cyan channel value, a magenta channel value, or a yellow channel value. The image processing device generates a target image by performing interpolation based on the luminance channel values and the single color channel values of the pixels of the input image, wherein each pixel in the target image corresponds in location to a pixel in the input image and has three color channel values generated by the interpolation.

Then, a camera module is used to shoot the reference chart, and an installation position and an installation posture of the camera module are acquired according to an internal parameter matrix and an external parameter matrix. When the camera module shoots the reference chart and an image is formed on an imaging plane of the camera module, a relationship between at least one image characteristic point of the image and the corresponding chart characteristic point complies with a standard relationship. The standard relationship is defined by the internal parameter matrix and the external parameter matrix.

摘要： A mechanism is described for facilitating sensors arrangement and shifting for multisensory super-resolution cameras in imaging environments, according to one embodiment. A method of embodiments, as described herein, includes arranging sensors of a camera such that pixel centers of pixels of an image are spread evenly across a pixel area having pixel planes corresponding to the sensors, where the image is captured by the camera. The method may further include re-arranging the sensors by dividing the sensors in pairs of sensors, where each pair of sensors corresponds to a pair of pixel planes, and shifting the sensors diagonally such that the corresponding pixel planes are adjusted accordingly for improving quality of the image.

摘要： An interactive projector is provided with a projection section adapted to project an image on a screen surface, a detection section, and a correction section. The detection section detects presence or absence of contact of the pointing element with the screen surface based in a relationship between a difference between a Z-coordinate value of the pointing element and a Z-coordinate value of the screen surface, and a difference threshold value set in advance. The correction section corrects at least one of the Z-coordinate value of the screen surface, the Z-coordinate value of the pointing element, and the difference threshold value based on a history of the Z-coordinate value of the pointing element.

摘要： This invention provides a system and method for automatic (non-manual) calibration of one or more cameras employs a tessellating calibration plate having a checkerboard tile pattern and a plurality of 2D codes embedded within the checkerboard pattern. Each 2D code encodes the (X,Y) coordinates that identify tile calibration feature locations in the pattern, and the remaining, surrounding tiles allow measurement of the corner positions as calibration features. One or more vision system camera(s) can be calibrated to a single coordinate system automatically. During calibration, an image of at least a portion of a calibration plate is acquired, the encoded data is decoded for at least one 2D code within the field of view of each camera and then the position of the field of view is determined on the calibration plate for each camera using the 2D code data and the checkerboard tile pattern.

摘要： Methods and thermal imaging cameras are provided for registering visible-light and infrared images within a thermal imaging camera to reduce a parallax error in the images. Registration generally includes detecting a first feature set in the visible-light image data, detecting a second feature set in the infrared image data and generating a plurality of overlapping alignments of the infrared image data and the visible-light image data. A similarity figure is calculated as a function of the relative alignment of the first feature set and the second feature set for each alignment and the alignment with the desired similarity figure is selected. The images are aligned and the camera displays at least a portion of the visible-light image data and/or at least a portion of the infrared image data.

摘要： A solid state image pickup apparatus includes a solid state image pickup device for receiving an optical image of an object and generating an electrical image signal representing the optical image of the object in synchronism with a driving pulse from a driving circuit. A sampling circuit generates a sampled image signal by sampling the electrical image signal read out of the solid state image pickup device with a first sampling pulse from a first pulse circuit synchronized with the driving pulse. An analog-to-digital convertor converts the sampled image signal to a digital image signal with a second sampling pulse from a second pulse circuit. A test signal generator generates a test signal which is synchronized with the driving pulse and alternately changes in level between consecutive pixels. A controller controls the phase of the first sampling pulse and the phase of the second sampling pulse relative to each other by processing the test signal.
