Viewing images from my little Canon Compact 980 is rather slow, compared to viewing images from my old D60 and D80 when loaded on the TV. I know both the D60 and D80 are 10.2 megapixels, while the Canon Compact is 14.7 megapixels.

Images from my DSLR bodies are very quick to view on my TV, and it seems instantaneously. But waiting for images to be viewed on the TV from the Canon Compact takes rather long, and it takes about six or seven seconds while the next image loads. I know it does not seem long, but when you are waiting with family to see the following images, it seems to take an age, and we soon get fed up just looking at a black screen!

I am viewing images on a three year old Toshiba widescreen TV, so not sure if it's because the telly is an older model :thinking:
 
Are you viewing directly from camera or via card reader slot on the TV or via a 3rd party viewer (media player - PS3 - laptop etc) If viewing directly from the camera then there are going to be differences as each cameras read speeds etc are controlled via the cameras built in cpu/software/hardware configuration among many other variables which makes a like for like comparison impossible. A DSLR has much more processing power than a small low price compact I should imagine.
 
As Gary says you might be using a slow SD card. Have a look not at the GB size but at the MB/s part. I always recommend nothing less than 45MB/s cards irrespective of GB size. Its all to do with the speed the card works at.

Realspeed
 
It could be the speed of the card, the size of the files, the amount of memory available in the TV and the processing power of the TV. Or a combination of all four. :shrug:

What are the average file sizes of the two cameras?

When I went from a 10MP camera to a 12MP camera, the average file size (for RAW files, but the principle applies) went from 8.5MB to 12MB. A 20% increase in pixels led to a 40% increase in average file sizes. :thinking:


If you want a very quick slideshow resize them to 1920 pixels on the longest edge, and they should be a fraction of the file size and very quick to load. :)
 
Thanks for the replies, I will have a look at getting a faster card. But I have just done a quick test, I tried three SD Cards that I have. I found that the Canon Compact is slow viewing on all three cards, while the D60 and D80 is fast viewing. This is viewing images on TV screen, by popping SD card into slot.

The D60 and D80 file sizes are about 4.27 MB

While the little Canon Compact is 7.32 MB

Looks like that may be the problem then the file size, just taking time to load. Images look better on the D60 and D80 than they do on the Canon Compact, even though the image file size on the Canon are bigger!

Do you mean resize the images, or turn the camera setting to record in a smaller image, such as Large Medium Small ?

That's the difference between a DSLR and a Compact. The number of pixels isn't everything. ;)

Resize the images. Never reduce the size in the camera. You never know when you're going to get the pic you want to print large. ;)

I'd put the pics on a USB pendrive if the TV has the option to take one. Keep memory cards for cameras.

Yes my TV does have a USB port, I thinks that's the option I will probably do. I will batch resize to USB pen, then keep original files separate.

Cheers :thumbs:
