A virtual surface is used for a standby mode for a device scanning optical codes. A virtual surface is designating as a rendering target for a camera of a mobile device used to detect and decode optical codes. The camera is started, with the virtual surface designated as the rendering target for the camera. The camera is stopped, without terminating a program that uses the camera, wherein the camera is in a standby mode. The camera is restarted to render to the virtual surface, after stopping the camera. An optical code is detected in an image acquired by the camera, after restarting the camera from the standby mode.

Virtual screen standby mode for mobile device camera

Incremental magnification is used to decode optical patterns, such a barcodes, in a scene. A first image of a scene is acquired using a first magnification of a camera, wherein the first image comprises a barcode. The barcode cannot be decoded. The magnification of the camera is increased by a predetermined magnification from the first magnification to a second magnification. A second image is acquired of the scene, including the barcode. The barcode is decoded after acquiring the second image.

Performance improvements for recognition of optical patterns in images using incremental magnification

For scanning optical patterns, such as two-dimensional QR codes, with a mobile device at increased distances, a first image is acquired. A region of interest likely containing the optical pattern in the first image is identified. The mobile device then zooms in on the region of interest and a second image is acquired. The optical pattern is then decoded using the second image.

Optical data exchange while preserving social distancing

An optical pattern is decoded in a scene. An automatic exposure feature of a camera is disabled. A first image is acquired and the optical pattern is detected in the first image. An exposure of the optical pattern in the first image is ascertained. At least one parameter of the camera is modified based on the exposure of the optical pattern. A second image is acquired using the modified parameter. The optical pattern in decoded in the second image.

Image exposure performance improvements for recognition of optical patterns

A mobile device may include a display, a camera, one or more processors, and one or more memory devices storing instructions. The instructions may cause the mobile device to detect an optical pattern in a scene using the camera, to receive a user action, and to execute a focus cycle of the camera after receiving the user action. The focus cycle may change the focal position of the camera from a first focal position to a second focal position. The instructions may also cause the mobile device to acquire an image of the scene using the camera at the second focal position to decode the optical pattern, generating an object identifier.
