Problems solved by technology

[0008] Optimization of one of the above three factors creates constraints on the other two
Thus, a larger viewfinder provides a better aesthetic, but at the expense of a slower frame rate (or refresh rate) or lower zoom level

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 1x 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 1x 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.

Description

technical field [0001] The present invention relates generally to digital video cameras, and more particularly, to a digital video camera having multiple viewfinders suitable for use within a portable electronic device. Background technique [0002] Portable electronic devices are becoming smaller and incorporating more functionality, such as traditional personal digital assistant ("PDA") functionality with cellular telephony and wireless e-mail capabilities. It is known to incorporate music and video players and camera applications for consumer market devices in addition to functions for business users. [0003] While traditional film cameras use light-sensitive film to capture images, digital cameras use electronic light sensors, such as charge-coupled device (CCD) or complementary metal-oxide-semiconductor (CMOS) chips. The term "photosensor" as used in this specification refers to any device or material capable of receiving and capturing radiant energy, and at least in ...
