User-configurable, gestural zoom facility for an imaging device

A computer system for facilitating gestural zoom operation of an imaging device, the computer system comprising:

• a memory;
• one or more processors operatively coupled to the memory;
• and
• program code executable by the one or more processors via the memory to perform a method comprising:
• receiving zoom configuration data of a user for configuring gestural zoom operation of the imaging device, the imaging device including a gestural zoom mode with a transfer function representative of a function curve that is user-configurable;
• and
• calibrate for the user the gestural zoom operation of the imaging device for gestural zoom mode, the calibrating of the gestural zoom operation using the received zoom configuration data, and the calibrating including:
• configuring the function curve for the user, wherein the function curve is a non-linear function curve that is user-configurable;
• and
• mapping a selected portion of the configured function curve to a gestural motion range of the user of the imaging device.

A computer-implemented method comprising:

• receiving, by one or more processors, zoom configuration data of a user for configuring gestural zoom operation of an imaging device, the imaging device including a gestural zoom mode with a transfer function representative of a function curve that is user-configurable;
• and
• calibrate for the user, by the one or more processors, the gestural zoom operation of the imaging device for the gestural zoom mode, the calibrating of the gestural zoom operation using the received zoom configuration data, and the calibrating including:
• configuring the function curve for the user, wherein the function curve is a non-linear function curve that is user-confiUrable;
• and
• mapping a selected portion of the configured function curve to a gestural range of the user of the imaging device.
