Claim Text:
1. A method comprising: receiving 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, wherein the particular frame rate is not changed in response to the instruction, and wherein a first portion of a line buffer is used to process the image data when the zoom operation is not implemented and a second portion of the line buffer is used to process the cropped image data after the zoom operation is implemented.
