Camera with multiple viewfinders
First Claim
1. A method for controlling the display of a portable electronic device having a user input device and a camera function;
- the portable electronic device including a photosensor chip having a sensor array of a predetermined number of rows and columns of pixels for converting radiant energy into electronic signals at a first frame rate for representing an image for display via a viewfinder;
the method comprising;
operating at a zoom level and viewfinder resolution for the camera application, the viewfinder comprising at least two viewfinder resolutions;
when the zoom level is 1×
, scaling the predetermined number of rows and columns of pixels to the viewfinder resolution and generating an image corresponding thereto; and
when the zoom level is greater than 1×
;
cropping a region of interest of the predetermined number of rows and columns of pixels in accordance with the zoom level;
scaling the cropped region of interest to the viewfinder resolution and;
generating an image with at least one of a higher frame rate and greater digital zoom when said viewfinder resolution is smaller than the largest viewfinder resolution.

Abstract
A novel method and apparatus for controlling the display of a portable electronic device having a user input device and a camera function; the portable electronic device including a photosensor chip having a sensor array of a predetermined number of rows and columns of pixels for converting radiant energy into electronic signals representing an image for display via a viewfinder. The method comprises selecting via the user input a zoom level and viewfinder resolution for the camera application, and in the event the zoom level is 1× then scaling the predetermined number of rows and columns of pixels to the selected viewfinder resolution and generating an image corresponding thereto; and in the event the zoom level is greater than 1× then cropping a region of interest of the predetermined number of rows and columns of pixels in accordance with the zoom level and then scaling the cropped region of interest in accordance with the viewfinder resolution and generating an image corresponding thereto.
