Abstract: Aspects of the disclosure are directed to self-synchronization of information data. In accordance with one aspect, an apparatus includes a receive physical (RX PHY) layer interface configured to send information data to a packet switch configured to suspend transmission of information data prior to arrival of a start of transaction (SOT) field and to commence transmission of information data upon arrival of the SOT field. The apparatus further includes a camera serial interface decoder (CSID) configured to receive information data from the packet switch; a frame switch configured to receive a start of frame (SOF) field from the CSID; an image signal processor (ISP) configured to receive decoded information data from the frame switch and to process decoded information data to generate a processed information data in a format compatible with an image display device; and a software module configured to enable the frame switch and the packet switch.

Abstract: Aspects of the disclosure are directed to error recovery. In accordance with one aspect, an apparatus includes a plurality of sensors configured to generate a plurality of sensor data; a plurality of sensor interfaces, wherein each one of the plurality of sensor interfaces is coupled to each one of the plurality of sensors; and an aggregator, coupled to the plurality of sensor interfaces, the aggregator configured a) to multiplex the plurality of sensor data into a single aggregator output stream, b) to detect a transmission error in the plurality of sensor data, and c) to recover the transmission error using an aggregator hardware without software involvement.

Abstract: This disclosure provides systems, methods, and devices for image signal processing that support compression of phase detection (PD) data. In a first aspect, a method of image processing includes receiving image data and first phase detection data corresponding to the image data; determining a first channel of the first phase detection data and a second channel of the first phase detection data; and coding the first phase detection data to determine second phase detection data by separately coding the first channel and the second channel. Other aspects and features are also claimed and described.

Abstract: An image processing system includes an image sensor configured to generate a video frame, the video frame having a data portion and a test portion, an inline front end (IFE) having at least one processing module, a first memory, a functional software register, and a test software register, the IFE configured to receive the video frame, process the video frame and store the processed video frame to a second memory, a test pattern generator configured to generate test data that is provided to the IFE during the test portion of the video frame, a multiple input signature register (MISR) test function configured to compute a MISR signature from the test data, and a comparison function configured to compare a verified version of the test data to the computed MISR signature in the IFE to determine whether a system interrupt should be generated.

Abstract: Techniques are described herein for processing image data. For instance, a technique can include obtaining a first image having a first exposure time and a second image having a second exposure time, the second exposure time greater than the first exposure time; determining at least one of: that one or more pixels of the first image has a pixel value below a first threshold value; or that one or more pixels of the second image has a pixel value above a second threshold value; preventing image processing on the one or more pixels based on the determination; replacing, based on preventing image processing on the one or more pixels, one or more pixel values of the one or more pixels with one or more replacement pixel values; and outputting the first or the second image, the first or the second image including the one or more replacement pixel values.

Abstract: Techniques are described herein for processing data. For instance, a process can include receiving input data by a symmetrical processing engine of two or more symmetrical processing engines coupled to an auxiliary processing engine. The process can further include receiving an indication to process the input data using a module of the auxiliary processing engine, transmitting output data to the auxiliary processing engine, receiving processed data from the auxiliary processing engine, further processing the processed data in one or more portions of a pipeline of modules of the symmetrical processing engine, and outputting the further processed data.

Abstract: Disclosed are systems, apparatuses, processes, and computer-readable media to capture images with subjects at different depths of fields. For instance, a method of processing image data includes obtaining a first image captured using an image sensor with a first exposure. The method may further include obtaining a second image captured using the image sensor with a second exposure. The method may include compressing the second image based on a comparison of the second image with the first image and storing the compressed second image in a memory. The method may further include obtaining the compressed second image from the memory and decompressing the compressed second image based on a difference between the compressed second image and the first image. The method may further include generating a combined image at least in part by combining the first image and the second image.

Abstract: Systems and techniques are provided for generating an HDR image. An example method can include obtaining a first image and a second image that has an exposure that is greater than an exposure of the first image; setting pixels of the first image that are below a minimum threshold to a minimum value and pixels of the second image that are above a maximum threshold to a maximum value; retrieving, from memory, a compressed version of the first image with the pixels set to the minimum value and a compressed version of the second image with the pixels set to the maximum value; generating a first decompressed image including the first image with the pixels set to the minimum value and a second decompressed image including the second image with the pixels set to the maximum value; and generating an HDR image based on the first and second decompressed images.
