Abstract
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
Claims29
A method comprising:
- receiving an instruction to perform a zoom operation;
- sending window information to an 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;
- and
- upscaling the cropped image data to generate a zoomed image.
An apparatus comprising:
- means to send window information to an image sensor in response to an instruction to perform a zoom operation, the window information corresponding to a portion of the image sensor;
- means to receive cropped image data corresponding to the portion;
- and
- means to upscale the cropped image data to generate a zoomed image.
A tangible computer readable medium storing processor-executable instructions that, when executed by a processor, cause the processor to:
- send window information to an image sensor in response to an instruction to perform a zoom operation, the window information corresponding to a portion of the image sensor;
- receive cropped image data corresponding to the portion from the image sensor;
- and
- upscale the cropped image data to generate a zoomed image.
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 in response to the instruction;
- receiving cropped image data corresponding to a portion of 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.
A system comprising:
- a processor;
- and
- memory accessible to the processor, wherein the memory includes instructions executable by the processor to:
- send window information to an image sensor in response to an instruction to implement a zoom operation;
- send a request to reduce a pixel clock rate of the image sensor to the image sensor, wherein the request causes the pixel clock rate to be reduced from a first pixel clock rate to a second pixel clock rate that is less than the first pixel clock rate;
- receive cropped image data corresponding to a portion of the image sensor that is associated with the zoom operation, wherein the cropped image data is received from the image sensor at the second pixel clock rate;
- and
- upscale the cropped image data to generate a zoomed image.
