Abstract: Systems and methods are described for generating image content. The systems and methods may include, in response to receiving a request to cause a sensor of a computing device to identify image content associated with optical data captured by the sensor, detecting a first sensor data stream having a first image resolution, and detecting a second sensor data stream having a second image resolution. The systems and method may also include identifying, by processing circuitry of the computing device, at least one region of interest in the first sensor data stream, determining cropping coordinates that define a first plurality of pixels in the at least one region of interest in the first sensor data stream, and generating a cropped image representing the at least one region of interest.

Abstract: In one general aspect, a method can include capturing, using an image sensor, a first raw image at a first resolution, converting the first raw image to a digitally processed image using an image signal processor, and analyzing at least a portion of the digitally processed image based on a processing condition. The method can include determining that the first resolution does not satisfy the processing condition; and triggering capture of a second raw image at the image sensor at a second resolution greater than the first resolution.

Abstract: Aspects of depth map generation and post capture focusing and re-focusing are described. According to one embodiment, a depth map is generated. The depth map may include a mapping among relative depth values in a field of view of an image based on a difference between pixels of a first image and pixels of a second image. An edge map may also be generated by identifying edges in at least one of the first image or the second image. Using the depth map and the edge map, the relative depth values in the depth map may be smoothed using the edge map. In this manner, certain discontinuities in depth values may be smoothed within edge-bounded regions defined by the edge map. The depth map may be used for focusing and re-focusing, for example, or for object extraction, scene understanding, or gesture recognition, among other imaging processes.

Abstract: Aspects of calibration of sensors are described. In one embodiment, a characteristic associated with a first or a second sensor is identified. The characteristic may be identified before or after assembly of a device including the first and second sensors. In turn, an operating characteristic of at least one of the first sensor or the second sensor may be adjusted based on the identified characteristic. Further, a first image may be captured with the first sensor and a second image may be captured with the second sensor. An attribute of the second image, for example, may be adjusted to substantially address any difference between the attribute of the second image and a corresponding attribute of the first image using the characteristic for calibration. The adjustments described herein may assist various processing techniques which operate on pairs of images, for example, particularly when a heterogeneous mix of sensors is used.

Abstract: A processor architecture and method are shown which involve a cache having heterogeneous cache sets. An address value of a data access request from a CPU is compared to all cache sets within the cache regardless of the type of data and the type of data access indicated by the CPU to create a unitary interface to the memory hierarchy of the architecture. Data is returned to the CPU from the cache set having the shortest line length of the cache sets containing the data corresponding to the address value of the data request. Modified data replaced in a cache set having a line length that is shorter than other cache sets is checked for matching data resident in the cache sets having longer lines and the matching data is replaced with the modified data. All the cache sets at the cache level of the memory hierarchy are accessed in parallel resulting in data being retrieved from the fastest memory source available, thereby improving memory performance.
