Methods, devices, and computer program products for managing a dual camera mode (DCM) are provided. The method obtains primary image data for a scene in a first field of view (FOV) of a first digital camera unit (DCU) and image-related information indicative of an attribute of interest (AOI) associated with the primary image data. A DCM status is determined based on the AOI. A secondary data capture operation is implemented at a second DCU based on the DCM status determined. The second DCU includes a second FOV that is different than the first FOV. The secondary data capture operation obtains secondary image data. The method manages storage of the primary image data and the secondary image data.

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.

An electronic device is provided. The electronic device includes a camera module, a sensor module, at least one processor configured to be operatively connected to the camera module and the sensor module, and a memory configured to be operatively connected to the at least one processor. The memory may be configured, when executed, to cause the at least one processor to acquire a plurality of first images having a first attribute and at least one second image having a second attribute for a designated time by controlling the camera module according to a photographing mode of the camera module determined based on at least one of illuminance detected through the sensor module and scene information detected through the camera module, extract information on an event section when the event is detected from the plurality of first images, and select and buffer at least one third image from the at least one second image according to the photographing mode, generate at least one piece of first content based on the information on the event section of the plurality of first images, and select at least one fourth image by evaluating at least some of the at least one third image, and generate at least one piece of second content based on the selected at least one fourth image.

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 some embodiments, a camera captures a sequence of input images. These input images are then merged by a massively parallel processor into a merged intermediate image, which is represented in memory as floating point numbers of a greater bit depth than the bit depth of the input images, thus creating a cumulative image representing a long exposure. After finishing exposure with a desired number of input images, the merged image is tonemapped with an HDR tonemapping operator. Other embodiments are shown and discussed.

An imaging apparatus to be remotely controlled by an external electronic device includes: a communication unit that communicates with the electronic device; an imaging unit that captures a moving image of a subject to generate moving image data from which still image data is to be extracted; a storage unit that stores, in a recording medium, the moving image data generated by the imaging unit; and a control unit that controls an operation of the imaging apparatus. The control unit performs a process of generating the moving image data in response to a first request from the electronic device and generating the still image data by extracting at least one frame image from the moving image data stored in the recording medium, in response to a second request from the electronic device, and causes the communication unit to transmit the generated still image data to the electronic device.

An image data transmission system and an image data transmission method are provided. The image data transmission system includes an image sensing device, a master device, and a serial transmission bus. The serial transmission bus electrically connects the image sensing device and the master device. The master device transmits a read command to the image sensing device through the serial transmission bus, and the image sensing device transmits a first data sequence to the master device through the serial transmission bus in response to the read command.

The processor obtains an exposure command and a first quantity, controls the image capturing circuit to perform an exposure operation to capture an image according to the exposure command, and determines whether a quantity of the image reaches the first quantity. When the quantity of the image does not reach the first quantity, the processor performs the operation of controlling the image capturing circuit to perform the exposure operation to capture the image again. When the quantity of the image reaches the first quantity, the processor stops controlling the image capturing circuit to perform the exposure operation.

A method, computer system, and a computer program product for image capture prevention is provided.
