Embodiment Construction

[0014] The present disclosure provides improved APIs for cameras and sensors. Such as figure 1 As shown, the API (sometimes referred to as the "interface") is preferably designed for use with the mobile device 100, although it can be used on any device that has a camera 102. The API is configured to control a type of hardware configuration based on an instruction set.

[0015] It is assumed that the device 100 includes an operating system (OS) 210 and discrete applications 220 . OS 210 coordinates the functions of applications 220 , integrated camera 202 (the terms camera and sensor are used interchangeably throughout this written description), and display 204 . OS 210 further includes camera API 212 and display API 214 , where camera API 212 communicates with camera 202 and display API 214 communicates with display 204 .

Abstract

A system for acquiring digital images by a device with an integrated camera includes an application programming interface (API). The API is adapted to receive preprocessing and other instructions from discrete applications operating on the device. The API is also adapted to handle multiple image acquisition requests using pipeline configurations.

Description

technical field [0001] The present application relates to methods and systems for acquiring digital images in devices. In particular, the present disclosure relates to an application programming interface (API) that allows a separate program installed on a device to control a digital image sensor on the same device. Background technique [0002] Many modern devices rely on an operating system from one vendor and hardware from one or more other vendors. Further, the device may include additional programs or applications from third suppliers. [0003] On a device, the operating system includes an application programming interface (API) that oversees application control of the operating system or hardware (eg, display, touch screen, audio output, network connections, digital image sensor, etc.). These APIs provide common instruction guidelines for executing functions on hardware. [0004] Current camera APIs may include high-level guidelines, such as instructions for acquiri...
