FIG. 1 illustrates a user facing view and a world facing view of a multi-camera. device of the present disclosure, in accordance with embodiments. As illustrated, in embodiments, multi-camera device 100 may include 3 camera sensors 106 co-disposed on a world facing side of multi-camera device 100 for depth photography or depth video applications during a depth camera mode of operation. A main one of the 3 camera sensors 106 may be employed for conventional photography during a single camera mode of operation.

Unlike traditional smartphones or computing tablets where the shutter button is typically horizontally centered and below the centerfold of the device, the position of the shutter button 104 of multi-camera device 100 intelligently accounts for the physical locations of the world-facing camera sensors. More specifically, in embodiments, multi-camera device 100 may be configured to provide a soft shutter button 102 at a location on an opposite side to the world facing side, the user facing side, coordinated with locations of the 3 camera sensors 106 that reduce likelihood of blocking of one or more of the 3 camera sensors 106. The user facing side may also be referred to as the front side of multi-camera device 100, and the world facing side may be referred to as the rear or back side of multi-camera device 100.

In embodiments, the 3 camera sensors 106 may include one high resolution camera sensor (8MP) and two stereo camera sensors (720p). All 3 camera sensors, the high resolution camera sensor (8MP) and the two stereo camera sensors (720p) are employed during the depth camera mode of operation and are synchronized by logic to concurrently capture multiple frames with identical frame sequence numbers, whereas only the high resolution camera sensor (8MP) is employed during the single camera mode of operation. In embodiments, the 3 camera sensors 106 may be arranged in a triangular pattern with the high resolution camera sensor (8MP) disposed proximally at the center of a side edge, and the two stereo camera sensors (720p) disposed proximally near the side edge at the top and bottom edges.

In embodiments, multi-camera device 100 may be configured with camera logic to place the soft shutter button 102 (also referred to as trigger) at the lower right corner of the user facing (front) side of multi-camera device 100 to guide a user in holding the multi-camera device 100 to reduce the likelihood of the user's hands or fingers blocking one or more of the 3 camera sensors 106. See also FIG. 2 for the complementary placement of the soft shutter button 102 or trigger, when the multi-camera device 100 is operated in a landscape orientation.

When the soft shutter button is activated, the multi-camera device operates with all camera sensors sensing concurrently and their captured frames synchronized and numbered in sequence.

Referring now to FIG. 3, wherein another user facing or front view of multi-camera device 100, in accordance with embodiments, is illustrated. As shown, in embodiments, multi-camera device 100 may be configured with camera logic (e.g., view finder logic) to provide a main view finder 302 for the one high resolution camera sensor, and two picture-in-picture viewfinders 304a and 304b for the two stereo camera sensors.

In embodiments, multi-camera device 100 may be configured with a camera preview window (not shown) for a user to select the depth camera mode of operation or the single camera mode of operation. In response to a user selecting the depth camera mode, a new preview display that shows all of the camera sensors 106 in real-time will be presented. The background of the main preview surface 302 will display the main high resolution camera frame, while two smaller picture-in-picture windows 304a and 304b will display the stereo camera previews.

Referring now to FIG. 4, wherein still another user facing or front view of multi-camera device 100, in accordance with embodiments, is illustrated. As shown, in embodiments, the multi-camera device 100 may be configured with camera logic (e.g., blocking determination logic) to determine whether one or more of the 3 camera sensors 106 is blocked or obscured by either the user's hands, fingers or by another object, and provide an alert 102 if at least one of the 3 camera sensors 106 is blocked. In alternate embodiments, in addition to or in lieu of a visual alert 102, an audio and/or mechanical alert, such as vibration, may be provided.

In embodiments, in response to a user selection of the depth camera mode, the multi-camera device 100 may switch from the single camera mode to the multi-camera mode operation. At this time, a scan may begin to evaluate if any or all of the stereo cameras 106 are being blocked or obscured. If a block or obscure state is flagged, an alert message in the camera preview (or a sound/voice or vibration alert) may be provided to indicate that the multi-camera device 100 is blocked or obscured. In embodiments, the alert message and/or signals may continue and not go away until the user has adjusted their hands, fingers or any object, unblocking all the multi-camera sensors 106.

In embodiments, multi-camera device 100 may be configured to perform a threshold scan of the preview image to determine if one or more of camera sensors 106 is blocked, thus ensuring all three world-facing camera sensors are unobscured at the same time for depth photography or depth video application.

FIG. 5 illustrates a process for determining occlusion, blocking or obscuring of one or more of the camera sensors, in accordance with embodiments. Process 500 may be performed by e.g., a camera application within multi-camera device 100.

At blocks 502 and 504, RGB images of two stereo camera sensors may be received.

At block 505, the images of the two camera may be smoothed, e.g., using a Gaussian kernel. At block 506, the images of the two cameras may be down-sampled, e.g. to 80×45.

At block 508, the down-sampled images may be converted to CIE-LAB color space images (CIE=International Commission on Illumination).

At block 510, color histograms for both a and h channel may be built for both images.

At block 512, the two histograms may be compared using l_i or X² distance, where l_i stands for the distance of the histograms, and X² stands for the Chi-Squared distances of the histograms.

At block 514, a determination may be made on whether the distance is greater than a threshold? The threshold value may vary dependent on applications, e.g., quality desired, and/or lighting environments, low light and/or high, intense, reflective light environments. The threshold values may be empirically determined.

At block 516, if a result of the determination indicates that the threshold is exceeded, an occlusion, i.e. blocking, conclusion may be drawn. Further, on conclusion of occlusion, an alert action (audio, visual, and/or mechanical) may be taken as earlier described.

At block 518, on the other hand, if a result of the determination indicates that the threshold is not exceeded, no occlusion, i.e. blocking, conclusion may be drawn.

Before further describing multi-camera device 100, it should be noted that while for ease of understanding, multi-camera device 100 has been described as having 3 camera sensors 106, the present disclosure is not so limited.
