Android :: Speed Up Camera Snaps

Apr 20, 2010

Apparently auto focus in a phone camera isn't all it's hyped up to be. To get faster performance (the time from pressing the shutter button to the picture being taken is usually slowed down by the camera trying to find focus in autofocus mode (and sometimes missing completely and giving up if the subject is dark or lack contrast). I'm not sure about all Android phones, but my Acer Liquid has a focus setting either 'infinity' or 'auto'. From what what I understand about photography, on a small lens such as on a camera phone, the DOF (Depth of Field) is very large, and when the focus is set to the hyperfocal length (the 'infinity' setting), everything from infinity to about 2.5 ft is in focus. I confirmed this with my phone (set focus to infinity, see what the closest thing that's in focus). So what this really means is for almost all regular picture-taking, it should be set to 'infinity' for faster performance, and only set to 'auto' when one needs to take pictures of objects closer than about 2.5 ft, like a 'macro' mode. So it would've actually made more sense if Android Camera app were to label the two settings '0-2.5 ft auto focus' and 2.5-infinity fixed focus'. If your camera has this setting, give it a try and see if it's snappier.

Android :: Camera ISO Setting / Shutter Speed

Aug 23, 2010

I am looking for a way to change the light sensitivity of my Evo 4G camerea. I know it is not the camera's shutter speed because it is a digital camera. The next most relevant aspect is the ISO setting, but the Android SDK does not have a way to manipulate it. Does any one know an alternative? i.e scene mode, exposure or effects.Does anyone have the run down on what scene mode values represents?

Android :: Speed Camera Application And Google Navigation

Sep 20, 2010

I use google navigation which I think is a brilliant navigation system seeing as it's completely free! The only downside is that it doesn't pick-up speed cameras. Does anyone know of any good speed camera apps that can run in the background or in conjunction with google navigation?

HTC Desire :: Any Way To Improve Camera (Shutter Speed)?

Aug 26, 2010

Does anyone else find find the camera on the Desire extremely sensitive to any hand movement while taking a picture? I found the camera on my old iPhone 3GS much better in this department (although the picture quality overall was not as good). And I know that a phone is no replacement for a dedicated camera, but is there any way to improve the shutter speed/sensitivity to movement?

HTC Incredible :: Camera Shutter Speed Is Awful

May 13, 2010

Is anyone else having issues with shutter speed? I can't take pictures that are perfectly clear. Most of the people are clear, but usually someone is moving which leaves a big blur.Before people say it's camera shake, I know the difference between shake and shutter blur. It seems the shutter is staying open too long to allow enough light in for proper exposure.

HTC EVO 4G : Text Messages Won't Scroll Up / Snaps Back To Newest?

Jun 10, 2010

Weird issue here but very very frustrating. When I'm scrolling up through a conversion to view old texts in a thread once I take my finger off the screen it immediately just snaps back to the bottom (newest texts) so I can't scroll up past like 6 previous texts. I tried a battery pull and still does it.

HTC Desire :: Camera Application To Shoot High Speed Videos?

Jun 17, 2010

I am a big fan of mythbusters and i'll bet that many of your are too. I like all those high speed camera shoots and i was thinking if would it be possible to make an app to use the camera to shoot high speed videos. I am not thinking like professional high speed video (those go up to millions of fps) but more like up to 1000 or 500. The desire should be able to shoot hd 720p video (lets hope with the next update) and may be would be possible to to make lower resolution high speed videos. I think the cpu is enough, but would the camera be able?

Motorola Droid X :: Phone Felt Sluggish / Shutter Speed On Camera Can Be Slow At Times?

Jun 25, 2010

I've read a couple of reviews on the Moto X and they all say that at times the phone felt sluggish and that the shutter speed on the camera can be slow at times. I know that "at times" doesn't mean it's a slow processor but vs. the incredible which is being touted as the phone that blows through any task with ease I was wondering which phone has better performance.

Android :: How Can Camera API Support To Two Camera Device?

Feb 1, 2010

The android camera API is bound to one camera device, but in some situation we have lots of camera device in a netbook or handset. We can't use the same application with different camera device dynamically. For example, we can select the camera device in the VLC (Video LAN Client) on windows because there is direct show on it, but we can't do that on android by camera API without changing the framework. Guys, is there any mistake at my understand? Is there any plan to modify framework to support this situation ?

Android :: How To Speed Up Animation?

Jul 21, 2009

I have a static background image, and a foreground that needs to be animated. I tried a couple different approaches but the animation seemed choppy. One thing I did was having 2 different views, constantly calling invalidate() on the foreground view. Another was to have only 1 surfaceview, redrawing the background image and the foreground on each step of the animation.

While a surfaceview offers an optimal way to do heavy-duty animation, having to redraw the background every time kills the performance. Neither produced a smooth animation. What is the best way to perform this kind of animation - static background and animated foreground?

Android :: Whats Your 3G / 4G Speed?

Sep 26, 2010

so I've been waiting for 4G in minnesota for a while now for my epic. They haven't announced it yet but. They've been. Tinkering with the towers lately and I've been seeing sme 4G coverage here are my mobile speed test results I was surprised considering I've been reading about people saying its more like 3 and a half G with speeds not much greater than 3G I realize however that right now there's almost 0 congestion and bandwith will slow considerably however the froyo update should even that out So what are your speeds?

Android :: How To Speed Up Emulator?

Aug 27, 2009

I have just started with development and would like to ask if Android's QEMU emulator uses any type of hardware acceleration.I made a simple Android program that extends the WebView activity and loads a webpage at start.That's all it does.It takes 35 seconds to cold start the emulator and acitivity from the Eclipse IDE. It takes 12 seconds to reload the acitivity when emulator is already up & running.Do you think these numbers are normal? Is there any possibility to speed up the emulation speed of QEMU?I can try to answer to this question myself. In the past, I used QEMU with KQEMU kernel module that remarkably boosted the emulation speed on X86 hardware. But Android runs on ARM CPU (not Intel or AMD CPU), so KQEMU module cannot be used here.My PC is Intel Core 2 Duo E6850 3.00GHz. 4GB RAM. Running Eclipse IDE 3.5 (Galileo) on 64 bit Ubuntu Linux 9.04.

Motorola Droid X :: Camera VS HTC Incredible Camera

Jul 17, 2010

So I spent the last hour or more in my backyard in 107 degrees taking pictures of flowers at stock settings with both phones. NOT an easy task I will tell you that. My back hurts, but besides that... I did my best to show the best quality of BOTH cameras, because they are both great. I realize that not everyone will agree with me, or will think I messed with something in my pictures. But these are all completely stock settings, not messed with at all. I only touched the flash on/off button.

My decision is I like the X camera better, it is easier to focus, and much snappier. Plus designated camera button! I found on the Incredible while the pictures look great on the phone itself and in gallery, that as soon as they were uploaded the colours looked washed out and not as great. I know this is due to the AMOLED screen. But both overall great. My decision is the X though.



NOTE: Inc would NOT focus any closer without being extremely blurry, tried a gazillion times.

Android :: Want To Improve Scrolling Speed

Mar 30, 2009

Currently, attempting to scroll when the text view has large amount of text makes the app completely unresponsive. It doesn't ANR, but it doesn't respond either. I've tried occasionally removing some text from the text view and removing some spans also, but it doesn't seem to help much. Any idea how to improve scrolling? It takes ages to scroll up or down. I also tried throttling touch events but it hasn't helped either.
