AI Technical Summary

Technical Problem

Existing computing devices, particularly smartphones, lack smooth and efficient runtime zoom capabilities for images outside specific applications due to high power consumption and inadequate performance of convolutional neural networks (CNNs) in providing perceptually smooth zoom animations.

Method used

A method involving a computing device that identifies a region of interest (ROI) using region histogram analysis and CNNs to determine a scaling factor, generates a sequence of intermediate-sized image frames through downscaling, and renders an animation using these frames to achieve a smooth zoom effect while optimizing power usage.

Benefits of technology

Enables smooth and efficient runtime zoom operations across various content on computing devices, reducing power consumption and enhancing user experience by leveraging CNNs for fine resolution and animation.

Abstract

A system and method for performing a zoom operation on a display of a computing device, comprising: identifying a region of interest (ROI) of an image displayed on the display based on zoom user input; determining a scaling factor for the final zoomed display of the ROI based on image rendering requirements and / or the inference speed of a frame-generating convolutional neural network (CNN); using the CNN to generate the final zoomed display of the ROI with respect to the determined scaling factor; downscaling the final zoomed display to generate a sequence of intermediate-sized image frames, each having dimensions smaller than the dimensions of the final zoomed display of the ROI and larger than the dimensions of the ROI; and rendering an animation of the change in the display size of the ROI using the sequence of intermediate image frames of the ROI.
