Abstract: Approaches are described for managing the processing of images or video on a computing device. A portable computing device can include one or more dedicated components, such as an application-specific integrated circuit (ASIC) or other dedicated processor component, to be integrated into the computing device to perform at least a portion of the imaging processing of captured images or video. For example, the dedicated processor component can enable the offloading of basic image signal processing, as well as higher level or “machine vision” processing from the device processor of the device. In this way, the dedicated processor component can perform signal processing for which the input is an image (or video), and where image or video data can be analyzed, interpreted and/or manipulated to generate an output, the output of image processing being either an image or a set of characteristics or parameters related to the image. The output can be provided to a device processor for further processing.

Abstract: The amount of resources needed to provide automatic exposure control (AEC) for a camera of a computing device, as well as the amount of latency required to determine an appropriate exposure setting for current conditions, can be improved utilizing an ambient light sensor (ALS) that is integrated with a camera module corresponding to the camera. The ALS can capture data regarding the amount of ambient light around the device, and a microprocessor or other component of the camera module can analyze the data using an AEC algorithm or other such process to determine one or more initial exposure settings for the camera. This process can be completed without sending image data to a host processor or other such component. Providing relatively accurate initial exposure settings can, in at least many situations, enable the AEC algorithm to more quickly converge to proper settings than is possible using conventional approaches.

Abstract: A computing device having multiple sensors can operate in different modes, wherein each mode causes data captured by different sensors to be transmitted to a processing component for analysis. In one example, a computing device includes one or more pairs of image sensors. Each pair can be configured such that the transmit lines of the sensors are selectively connected to a host processor or other such component. When in a normal operational mode, the switch can be configured to cause data captured by a first image sensor to be transmitted to a receive input of the host processor. When image data from a second image sensor is to be analyzed, the switch can be adjusted such that the device operates in a bypass mode, such that only data from the second image sensor is received and analyzed by the host processor.

Abstract: Devices, systems and methods are disclosed for discontinuously capturing and transmitting images from a camera. The camera initializes and powers down on-demand components, awaiting a signal on an interrupt pin. Upon receiving a signal on the interrupt pin, the camera powers up the on-demand components, captures a series of images and transmits the series of images. The discontinuous transmission of images allows the camera to reduce a power consumption and a memory usage while reducing a latency between a capture request and the transmission of images.
