Screenshot of game 6.5MB Really?

[TJ82]

Just noticed this now. I was trying to show a friend what a game was like (Oceanhorn, it's on sale today by the way) so took a screenshot to send them in chat (WeChat).

I clicked send full image and it said it was 6.5MB.

Does that not seem a tad large for a phone screenshot of a game? Or am I behind the curve on this?

depending on your phone your screen shot is the resolution of your display. so if you have a 6plus and you took a screen shot its a 1920x1080 image

actually it'd be 2208x1250 (not entirely exactly sure of the resolution 6 Plus renders at, but it renders around that resolution then gets downscaled, but screenshots on a 6 Plus count as 2208x1250 resolution)

Yeah, because that’s what? A 6+ @ 1920x1080x32bpp (or 2208x1242...)? That's right at ~6.6MB (assuming a “high quality” quality JPG) JPG compression can get an image down pretty small without losing much perceivable IQ, but not much control over a screenie (unless you shoot, manually compress, and send)

Interesting. The screen capture on a 6+ uses the internal “pre-downscaled” frame buffer vs. screen rendered output? BTW, that internal res I believe is 2208x1242

not entirely sure but if you look at EXIF of screenshots, clearly shows the screenshot at 2208x1242, and yes the resolution is 2208x1242, i knew i was close

Ah fair play. Does make sense when it's broken down like that. Thanks

Yeah, that’s really interesting, I hadn’t really considered a screen cap on a 6+ and how it would actually render it.

I’m still a little baffled by that choice. I’m assuming we’ll see a “native” 3X retina iPhone in the very near future, and that was simply a component constraint compromise (and maybe a touch of battery consideration)

Yeah I can easily see apple putting a higher resolution display to match the native 3x, (2208x1242 panel) but that they couldnt get those in the Plus at the time because due to: 1080p panels being already easily in full production compared to a random 2208x1242 panels being made, and also battery constraints.

either the 6S or 7 will guranteed defitnetly have this newer even higher resolution screen to match the 3x, 14nm Apple A9 and a increased battery capacity(due to smaller, more powerful, more power efficient SoC on a 14nm node) will easily make up for it and even give better battery life then what the Plus already has now

Pardon my “duh” moment above, screen caps are PNG ...

Funny, I believe the screen caps I’ve done are a good bit smaller (I shot a ton for screen shots in an app), but of course we’re talking like like ~3.7x more resolution on a 6+ @ 2208x1242 vs. a 5/5S with 1134x640.

oh yea, i forgot it downscales.
