Problems solved by technology

However, system resources in portable devices are very limited
Constructing a preview image or video image with depth information is very time-consuming due to the high complexity of depth information calculation
In existing portable devices, there can be a noticeable delay between the start of image capture and the display of the first preview image, even though the computation has been distributed across multiple image processing pipelines

Abstract

The invention provides a method for display delay enhancement and a portable device. The portable device includes: a dual camera device, continuously capturing a sequence of frame pairs; a video encoder; a display; a processor, configured to obtain a first depth map associated with one or more previous frame pairs of the frame pairs, and generate a first output image based on a current frame pair of the frame pairs and the first depth map associated with the one or more previous frame pairs, and sends the first output image to the display. The processor obtains a second depth map associated with the current frame pair, and generates a second output image based on the current frame pair and the second depth map associated with the previous frame pair, and sends the second output image to the video encoder. The method for display delay enhancement and the portable device can reduce display delay of an image preview path and maintain image quality of a video recording path with high quality.

Description

[0001] 【CROSS-REFERENCE TO RELATED APPLICATIONS】 [0002] This application claims priority to U.S. Provisional Patent Application Serial No. 62 / 249,654, filed November 2, 2015, which is incorporated herein by reference. [0003] 【Technical field】 [0004] The present invention relates to image processing technology, in particular, to a display delay enhancement method and a portable device. [0005] 【Background technique】 [0006] Due to advances in technology, today's portable devices are smaller and more powerful. Users typically use portable devices to capture images or record video. However, system resources in portable devices are very limited. Due to the high complexity of depth information calculation, it is very time-consuming to construct preview images or video images with depth information. In existing portable devices, there may be a significant delay between the start of image capture and the display of the first preview image, even though the computation has b...
