Systems, apparatuses and methods for triggering actions in response to capturing and characterizing image data. Real-time characterization techniques include object and shape recognition analytics to detect specifically designated content in captured image data. Actions are triggered based upon such detection. Global data access and distribution systems and methods are provided, particularly for use by law enforcement agencies and designated alert systems.

Techniques for multiplexing audio recordings. Systems and methods for multiplexing and synchronizing audio recordings using data markers in the recorded files.

Systems and methods are provided that capture and process frames of frame data. An image sensor captures frames of frame data representative of light incident upon the image sensor using a rolling shutter and outputs the frames of frame data. The image sensor captures at least one of the frames over a frame capture interval and then waits over a blanking interval before capturing another frame. A buffer receives and stores the frames output by the image sensor. An image signal processor retrieves the frames from the buffer and processes the frames over successive frame processing intervals to generate a video having a time interval per frame greater than the frame capture interval. At least one of the successive frame processing intervals is greater than the frame capture interval and is less than or equal to a sum of the frame capture interval and the blanking interval.

According to one aspect, there is provided an apparatus comprising at least one processing unit and at least one memory. The at least one memory stores program instructions that, when executed by the at least one processing unit, cause the apparatus to obtain a set of captured still images captured with a camera, detect at least one face in the captured still images, and cause display of the detected at least one face on a display providing a live viewfinder feed of a scene to be captured as an additional display element while providing the live viewfinder feed on the display.

Frame buffering technologies are described. An example device includes camera hardware configured to receive a plurality of frames, a first memory device that implements a buffer, and a second memory device that consumes greater power than the first memory device. The device also includes processing circuitry coupled to the camera hardware, and to the first and second memory devices. The processing circuitry is configured to form a plurality of snapshot frames using a subset of the plurality of the received frames, to store the plurality of snapshot frames to the buffer implemented in the first memory device, and to receive a capture command. In response to receiving the capture command, the processing circuitry may identify, as a capture-selected snapshot frame, a first snapshot frame of the plurality of snapshot frames stored to the buffer, and push the capture-selected snapshot frame to the second memory device.

Systems and methods are disclosed that capture and compress frames of pixel data. In an implementation, an image sensor chip is configured to convert light into pixel data and generate compressed pixel data at a variable compression rate including applying a transform to pixel data associated with a pixel category from a plurality of pixel categories. The variable compression rate is within an available bandwidth of an output bus configured to output the compressed pixel data.

Methods, devices, and systems for continuous image capturing are described herein. In one embodiment, a method includes continuously capturing a sequence of images with an image capturing device. The method may further include storing a predetermined number of the sequence of images in a buffer. The method may further include receiving a user request to capture an image. In response to the user request, the method may further include automatically selecting one of the buffered images based on an exposure time of one of the buffered images. The sequence of images is captured prior to or concurrently with receiving the user request.

Systems and methods are disclosed that capture and compress frames of pixel data. In an implementation, an image sensor chip converts light into pixel data and generates transform data by applying a transform to a portion of the pixel data associated with a pixel category from a plurality of pixel categories and generates compressed pixel data at a variable compression rate by compressing the transform data. The variable compression rate is within an available bandwidth of an output bus that outputs the compressed pixel data.

A method and device for securing image data detected by an electronic device is provided. The electronic may include a camera. In one aspect, a method includes: capturing image data using the camera; based on the captured image data, detecting a security marker displayed by a display device, the security marker being periodically displayed to be undetectable by a human eye that is viewing the display device; and in response to determining that the security marker is detected by the electronic device, applying a security policy to the image data captured by the electronic device.

An image forming apparatus includes a sheet conveying portion, an image data outputting portion, a plurality of buffer memories, an image forming portion, and a timing control portion. At least one of the plurality of buffer memories corresponding to at least one predetermined channel among the plurality of color channels other than a head color channel is configured to store image data of two different pages individually. After the image data outputting portion starts outputting image data of the first page to the buffer memory corresponding to the predetermined channel, the image data outputting portion starts outputting image data of the second page to the buffer memory regardless of whether or not the image data of the first page has been read from the buffer memory.
