## Abstract

Methods, devices, and systems for controlling imaging operations in electronic image capture devices are disclosed. In some aspects, a device includes processor coupled to a camera module, a user input surface, and a memory. The processor can be configured to receive, from the user input surface, a continuous user input. The continuous user input can include, at least, a first portion and a second portion. The processor can be further configured to control a first imaging operation based on a first input type received during the first portion and control a second imaging operation based on a second input type received during the second portion. The first input type can include movement of an input element relative to the user input surface, for example, and the second imaging operation can be different than the first imaging operation.
