I was out in the woods the other day
taking pictures of the trees with
As we were walking and talking I came
with this idea. At least I hope it was me,
otherwise I owe him a drink.
Both our cameras have tilt sensors. When
you take a portrait shot, the camera
tag into the JPEG or RAW file
telling whatever image processing
program you use that this is the case and
you don't need to rotate images when
post-process them. Nice.
The image is also rotated when you
preview it on the LCD on the back of the
camera. Nice also. It means that you
need to keep twisting the camera then
look at a series of shots. Unfortunately it
does mean that portrait shots now take
less space and show less detail on the
landscape oriented LCD display on the
back of the camera.
A camera incorporating 'Tilt Sensor for
Playback' would use the same tilt sensor
that it used to work out the orientation
when you took the picture to rotate the
image if you twist the camera during
playback. Now you can use the whole of
the LCD display to look at that portrait
shot. There... that's better.
Review of the IXUS 55
from dpreview.com [st3f, May 26 2006]
||This is how cameras used to work before they got tilt-sensitive (display all photos the way they were taken). Given that it's doing something special to tilt the photo, what you really want is an option to switch the tilting off, rather than tilt it back again.
||Anyway, don't you have a magnify option?
||Soon enough, we'll have cameras that give their own slide shows on the wall.
||I have a magnify option. I have the ability
to turn auto-rotation off.
||What I want to do is use a photography
feature of the camera to control the
playback user interface which is... um...
why I posted the idea rather than being
content using the magnify option or
turning auto-rotation off.
||This reminds me of an idea I saw a few years back for a large virtual display on small-screen PDAs - it used solid-state accelerometers to detect movement of the display device, and allowed you to move a small zoomed "window" over a larger image simply by moving the PDA - don't know if it coped with rotation though. I'll try to find a link.
||Someone here suggested round format a while back. In it's favour, it would notch up the format wars another notch.
||Might be fun to have to rewrite JPEG encoding using polar coordinates.
||Doesn't PhotoShop have a filter for that already?
||*** Idea Baked ***
In Feb 2006 dpreview.com reviewed the
55 (aka Canon PowerShot SD450 Digital
ELPH) which has this feature. I have no
idea if this is the first camera to
incorporate the idea but it's the first I've
seen of it.
||From dpreview.com (linked), "New
features include [...] a nifty orientation
sensor that rotates the display of
images as you turn the camera round in
