摘要： Described are methods and apparatus for adjusting images of a stereoscopic image pair based on keypoint matches. The quality of the key point matches is first evaluated to determine whether the quality exceeds a keypoint quality threshold. If the quality level of the keypoint matches exceeds the threshold, the vertical disparity between the images of the stereoscopic image pair can be evaluated based on vertical disparity vectors between the keypoint matches. If the vertical disparity is below a threshold, no adjustment of the stereoscopic image pair may be performed. If the vertical disparity is above the threshold, an affine correction may compensate for pitch, roll, and scale differences between the images. A projective correction may compensate for yaw differences. The vertical disparity between the two images is then evaluated after the corrections to determine if additional adjustment should be performed.

摘要： In photography, High Dynamic Range (HDR) technology typically consists of (1) acquiring a wide dynamic range image and (2) adapting the wide dynamic range image to fit to the display range of the device. The first part can be achieved by using a special sensor or by combining two or more images with same or different exposures, and is optional. The second part, contrast adaptation, locally adapts the tone mapping function thus effectively re-using the available range. Described is a system and method that enables a user to create a new image by selectively combining contrast adapted and non-contrast adapted versions of the same image. The new image can retain the natural quality of the well illuminated areas and enhance salient features as selected by the user.

摘要： Described herein are methods and apparatus to adjust the convergence point of a stereoscopic image pair captured by an imaging device. In one method, a first image and a second image of a stereoscopic image pair are provided, and then shifting or cropping of the first image is performed to align the first and second image. This shifting or cropping is performed while preserving the second image. The method then includes determining a target horizontal image disparity based on a desired convergence point of the stereoscopic image pair and when the target horizontal disparity is greater than a predetermined maximum, the cropping of an outside dimension of the first image is limited. In some implementations it is limited to the predetermined maximum.

摘要： Described herein are methods, systems and apparatus to improve imaging sensor production yields. In one method, a stereoscopic image sensor pair is provided from a manufacturing line. One or more images of a correction pattern are captured by the image sensor pair. Correction angles of the sensor pair are determined based on the images of the correction pattern. The correction angles of the sensor pair are represented graphically in a three dimensional space. Analysis of the graphical representation of the correction angles through statistical processing results in a set of production correction parameters that may be input into a manufacturing line to improve sensor pair yields.
