Abstract
Abstract In accordance with the present invention, a new and improved digital camera has a capture mode of operation where a scene to be captured can be captured and stored in a removable memory device as a digital still image and subsequently retrieved and displayed on a LCD in a review mode of operation. Alternatively, the scene to be captured can be captured repeatedly and buffered to the LCD where the buffering rate is determined in a live view capture mode of operation allowing a user to preview the scene to be captured in various ambient lighting conditions. In one instance, under low ambient lighting conditions a user is able to manually adjust the live view/preview apparent image brightness level of tie displayed scene independently of any LCD brightness or contrast adjustments.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
100 words
An electronic device for displaying a buffered image, comprising: an image capture device having a range of exposure times for converting light to an electrical signal; and a programmable amplifier coupled to said image capture device and responsive to a manual indication from a user that the image is sufficiently obfuscated due to lighting conditions to lack discernible features for adjusting the strength of said electrical signal; wherein a set of controls icons are automatically displayed whenever the exposure time of said image capture device is at about 13.33 milliseconds or greater to help facilitate user adjustments to improve quality.
Claim 2
Dependent Claim
100 words
An electronic device for displaying a buffered image, comprising: an image capture device having a range of exposure times for converting light to an electrical signal; and a programmable amplifier coupled to said image capture device and responsive to a manual indication from a user that the image is sufficiently obfuscated due to lighting conditions to lack discernible features for adjusting the strength of said electrical signal; wherein a set of controls icons are automatically displayed whenever the exposure time of said image capture device is at about 13.33 milliseconds or greater to help facilitate user adjustments to improve quality.
Claim 3
Dependent Claim
49 words
An electronic device for displaying a buffered image according to claim 1 , wherein said programmable amplifier is further responsive to said manual indication from the user that the image is smeared for further adjusting the strength of said electrical signal to cause the display of an unsmeared image.
Claim 4
Dependent Claim
46 words
An electronic device for displaying a buffered image, according to claim 1 , further comprising: multiplying means responsive to said programmable amplifier for further increasing the strength of said electrical signal to cause the display of an image of sufficient detail to facilitate live view observation.
Claim 5
Dependent Claim
44 words
An electronic device for displaying a buffered image, according to claim 3 , wherein said multiplying means includes: an analog to digital converter for converting said electrical signal into a digital signal; and digital multiplier means for increasing the strength of said digital signal.
Claim 6
Dependent Claim
22 words
An electronic device for displaying a buffered image according to claim 4 , wherein said digital multiplier means is a digital multiplier.
Claim 7
Dependent Claim
21 words
An electronic device for displaying a buffered image according to claim 4 , wherein said digital multiplier means is a microprocessor.
