ABSTRACT:
This disclosure describes techniques for managing the clock speed of a bus during viewfinder mode in a digital camera device. The techniques involve determining a frame rate of frames displayed on a viewfinder, determining whether to adjust a clock speed of a bus based at least in part on the determined frame rate, wherein the bus is used to transfer the frames from a camera sensor to the viewfinder, and adjusting the clock speed of the bus upon determining that that the clock speed should be adjusted. The techniques may help ensure that the viewfinder delivers frames at a target frame rate. In addition, in some cases, the techniques may help to reduce power consumption by facilitating clock speed reductions in viewfinder mode.
