摘要： This disclosure describes barcode scanning techniques for an image capture device. The image capture device may automatically detect a barcode within an image while the image capture device is operating in a non-barcode image capture mode, such a default image capture mode. In one aspect, the detection of the barcode within the image may be based on a combination of identified edges and low intensity regions within the image. The image capture device may configure, based on the detection of the barcode, one or more image capture properties associated with the image capture device to improve a quality at which the images are captured. The image capture device captures the image in accordance with the configured image capture properties. The techniques may effectively provide a universal and integrated front-end for producing improved quality images of barcodes without requiring significant interaction with a user via a complicated user interface.

摘要： This disclosure describes techniques for detecting a barcode within an image. An image processor may, for example, process an image to detect regions within the image that may be barcodes. The image processor may identify regions of the image that exhibit a high concentration of edges and a high concentration of pixels with low optical intensity co-instantaneously as potential barcodes. The image processor may identify the regions using a number of morphological operations. The image processor may then determine whether the identified regions are actually barcodes by verifying whether the region have unique barcode features. The barcode detection techniques described in this disclosure may be independent of barcode size, location and orientation within the image. Moreover, the use of morphological operations results in faster and more computationally efficient barcode detection, as well as lower computational complexity.
摘要翻译：本公开描述了用于检测图像内的条形码的技术。图像处理器可以例如处理图像以检测图像内可能是条形码的区域。图像处理器可以识别呈现高浓度边缘的图像区域和具有低光强度的高浓度像素作为潜在条形码。图像处理器可以使用多个形态操作来识别区域。然后，图像处理器可以通过验证该区域是否具有独特的条形码特征来确定识别的区域是否实际上是条形码。本公开中描述的条形码检测技术可以独立于图像内的条形码尺寸，位置和取向。此外，使用形态学运算导致更快和更有计算效率的条形码检测，以及较低的计算复杂度。

摘要： This disclosure describes an efficient architecture for an imaging device that supports image registration for still images and video coding of a video sequence. For image registration, the described architecture uses block-based comparisons of image blocks of a captured image relative to blocks of another reference image to support image registration on a block by block basis. For video coding, the described architecture uses block-based comparisons, e.g., to support for motion estimation and motion compensation. According to this disclosure, a common block comparison engine is used on a shared basis for both block based image registration and block-based video coding. In this way, a hardware unit designed for block based comparisons may be implemented so as to work in both the image registration process for still images and the video coding process for coding a video sequence.

摘要： Systems and methods to selectively combine video frame image data are disclosed. First image data corresponding to a first video frame and second image data corresponding to a second video frame are received from an image sensor. The second image data is adjusted by at least partially compensating for offsets between portions of the first image data with respect to corresponding portions of the second image data to produce adjusted second image data. Combined image data corresponding to a combined video frame is generated by performing a hierarchical combining operation on the first image data and the adjusted second image data.

摘要： This disclosure describes image stabilization techniques for devices with image capture capabilities. An image capture device may capture two or more images and combine the image using the techniques described in this disclosure. In particular, the image capture device may compute motion vectors for a plurality of blocks of pixels of one of the images. In cases, the image capture device may also interpolate or extrapolate motion vectors for individual pixels or sub blocks of pixels using the block motion vectors. The image capture device may then average the first and second images by averaging each of the pixels of the first image with pixels of the second image that correspond to a location indicated by the plurality of motion vectors. The techniques may be particularly effective in reducing blur in image information resulting from certain movements during image capture or use of certain image capture technologies.
