摘要： A method, system, and computer program product to obtain a focus point of a current scene. The method includes performing a first focus procedure in a first direction via a main lens of a main camera of an image capturing device having at least two cameras. The method further includes concurrently performing a second autofocus procedure in a second direction that is opposite the first direction via at least one auxiliary lens of at least one auxiliary camera. The method further includes identifying a focus point within autofocus data collected during the first and second focus procedure. The method further includes, in response to determining the focus point was identified by the at least one auxiliary camera: terminating the first focus procedure; and automatically synchronizing a position of the main lens to that of the at least one auxiliary lens.

摘要： A method, a system, and a computer program product for dynamically adjusting sampling of a depth map based on detected motion in a current scene. The method includes capturing real-time scan data at a first resolution by a first camera and a second camera of an image capturing device. The method further includes synchronizing a first plurality of frames of the real-time scan data to create a plurality of synchronized frames at a first frame rate. The method further includes analyzing the synchronized frames to determine whether motion exists. The method further includes, in response to determining motion exists: determining, based on the plurality of synchronized frames, a rate of motion within the current scene; and dynamically calculating a target resolution and a target frame rate for a real-time depth map. The method further includes generating a real-time depth map at the target resolution and target frame rate.

摘要： An electronic device, computer program product and method provide automatic exposure control (AEC) convergence in a dual camera system. A main camera is triggered to perform AEC convergence procedure at a first frame rate. A display presents at least one of first images from the main camera. An auxiliary camera is triggered to perform AEC convergence procedure. A determination is made whether the AEC of the auxiliary camera has converged. In response convergence by the AEC, an exposure setting of the main camera is synchronized to the exposure setting of the auxiliary camera. The display presents a next image captured by the main camera operating with the synchronized exposure settings.

摘要： An electronic device includes an image capture device, such as a camera, a user interface and one or more processors. The one or more processors can receive an image from the image capture device and detect distortion occurring in the image. The one or more processors can then obtain weather data of a location where the image was captured and determine whether the weather data indicates a weather condition, such as fog, responsible for the distortion. Where this is the case, the one or more processors can perform distortion reduction on the image to reduce weather-related distortion occurring in the image. Otherwise, the one or more processors can present a prompt with a notification to clean at least a portion of the image capture device.

摘要： An apparatus includes digital camera equipment and a display that provides a viewfinder. A processor that is operatively coupled to the camera equipment, and to the display, controls the camera equipment and the display to provide a custom reticle that defines a region-of-interest having a shape corresponding to an object-of-interest as the object-of-interest appears in the viewfinder. One or more object templates may be stored in memory. The object templates contain location information and size information for one or more objects-of-interest in a geographic region where the apparatus is located. The processor may construct the custom reticle using one or more of the object templates. The processor can determine that an object-of-interest is displayed in the viewfinder and construct a custom reticle for that particular object-of-interest.

摘要： Various embodiments provide improved image resolution using a High Dynamic Range (HDR) image sensor. A computing device calculates long exposure settings and short exposure settings for image sensors of a computing device. The long exposure settings and the short exposure settings are applied to a first image sensor of the image sensors, and only the short exposure settings are applied to a second image sensor of the image sensors. Some embodiments use an interleaved High Dynamic Range (iHDR) image sensor as the first image sensor, and a Clear or Mono image sensor for the second image sensor. Various embodiments generate a synchronized image that includes a first image generated by the first image sensor and a second image generated by the second image sensor. Upon receiving the synchronized image, some embodiments fuse the first image and the second image to improve the image resolution of the first image capture.

摘要： A method and apparatus provide automatic stage scene detection. A first image of a scene can be captured using a luminance for automatic exposure control. A brightness contrast between a center region of the first image and areas surrounding the center region of the first image can be calculated. A brightness value can be ascertained for the entire first image. Whether the luminance of the first image should be adjusted can be determined based on the brightness contrast being greater than a contrast threshold and the brightness value for the entire first image being less than a brightness value threshold. The luminance for the automatic exposure control can be adjusted for correct exposure of the center region of the first image in response to determining the luminance of the first image should be adjusted. A second image of the scene can be captured based on automatic exposure control using the adjusted luminance.

摘要： A method and apparatus provide automatic stage scene detection. A first image of a scene can be captured using a frame luma for automatic exposure control. A brightness contrast can be calculated between a center region of the first image and areas surrounding the center region of the first image. A brightness value can be ascertained for the entire first image. The first image can be determined to be a stage scene image based on the brightness contrast being greater than a stage scene contrast threshold and the brightness value for the entire first image being less than a stage scene brightness value threshold. The frame luma for the automatic exposure control can be adjusted for correct exposure of the center region of the first image in response to determining the first image is a stage scene.

摘要： A method, system, and computer program product for generating a high dynamic range (HDR) image from a plurality of frames simultaneously captured by cameras of a portable device. The method includes detecting, by a main camera of the portable device, a current dynamic range level of a current scene. In response to detecting the current dynamic range level, a main camera exposure compensation value is applied to the main camera and an auxiliary camera exposure compensation value, which is different from the main camera exposure compensation value, is applied to at least one auxiliary camera. The method further includes simultaneously capturing a first frame by the main camera and at least one second frame by at least one auxiliary camera. The method further includes combining the first frame and the at least one second frame to create the HDR image.
