camera notes for the Nokia2760 phone. Written by JCPMA

PHOTO
-----
photo = maximum of 0.3 megapixels resolution (640 x 480 pixels).
Zooming is digital. You wind up with a small cropped photo of only 128x96 pixels!
ie. zooming is a waste of time. The only time where this may be useful, is when
zooming in may take advantage of the camera's auto exposure and thus improve lighting. Otherwise, you are better off with the 640x480 sized picture!

image sequence = takes a series of 3 jpgs (time duration = 1 sec.? unconfirmed?)

you have the capability to set the default picture/video name.

Photo capacity. In the upper right corner, there is a count-down type indicator which tells you how many photos you may still take within the alloted memory. This gauge is misleading! With every 2 photos (640x480 size) you take, the indicator goes down by 3-4 in number. For example, If the gauge says there is room for 50 photos, and you take 2 photos, the gauge will then refresh to the number "47". A good rule of thumb, is to therefore, divide that number by 2! A user can expect to be able to take at least 100 photos before the memory is full.

if you edit a photo image: ---> it saves it as a new .gif!!!
and then, if you use this gif for a wallpaper, it only covers up 75%-80% of the screen!.
That is because, any action done with the built-in phone editor will save the output as a gif file, and also a file which is 92x115pixels, LESS-THAN 128x160 pixels. (128x160 is the size the screen.)[5].
-What I would change if I could:
a) Have the built-in editor save files as .gif or .jpg format
b) have the built-in editor save/resize files as 128x160 pixels or more.



VIDEO
------
Zooming in for videoClips: Fortunately when you zoom in for video, the size of the video output resolution, ie the WidthxHeight stays the same., ie 128x96pixels. This is a nice size for a postage stamp.

video duration
-default = 9 seconds
-maximum = upto 2 min and 30 seconds.

audio is recorded via the built-in mic.

vidClip info:
~~~~~~~~~~~~
video file format = .3gp
Video codec = H263
FourCC: s263
videoBitRate = 63 kbps
AudioBitRate = 12 kbps
128x96pixels
color mode: YUV 4:2:0 Planar
FrameRate= 29.97 fps (?interpolated?)
FrameRate = 7.25 fps
Audio = AMR-NB (FourCC:samr), sampleRate=8000Hz, 1 Channel;
AudioBitrate 12 kbps; bits per sample=16


The 2760model only has 10MB of internal memory to work with; It is understandable, why the videoClip specs are so poor/low. However, given these specs., the mono audio sounds remarkably impressive. The video isn't great. The video quality is suitable for just having some fun. The only media type which approaches acceptable quality is the still photo at 640x480 resolution.[5].
