GENERATING A ZOOMED IMAGE

摘要

An apparatus and method of generating a zoomed image is disclosed. A particular method includes receiving an instruction to perform a zoom operation. Window information is sent to an image sensor based on the instruction. The window information corresponds to a portion of the image sensor. In addition, a request to reduce the pixel clock rate may be sent to the image sensor. The request may cause the image sensor to reduce the pixel clock rate such that a frame rate of image data captured by the image sensor is maintained. Cropped image data corresponding to the portion of the image sensor is received. The cropped image data is upscaled to generate a zoomed image.

1. A method comprising:
receiving first image data from an image sensor at a first pixel clock rate; receiving an instruction to perform a zoom operation; sending window information to the image sensor based on the instruction, the window information corresponding to a portion of the image sensor; receiving cropped image data corresponding to the portion from the image sensor that is associated with the zoom operation, the cropped image data received at a second pixel clock rate that is slower than the first pixel clock rate; and upscaling the cropped image data to generate a zoomed image, wherein prior to receiving the instruction, the image sensor outputs image data at a particular frame rate, and wherein the particular frame rate is not changed in response to the instruction.
