DSC-S75 - The 14 bit A/D Converter

Can anyone enlighten me as to the 14 bit A/D converter? Is that an internal bit depth or an external bit depth? In otherwords, will I get to work with all 14 bits/pixel in Photoshop, or is it just used inside the camera for processing, resulting in only the standard 8 bits/pixel available in Photoshop. Thanks for your help! I preparing to make my first digital camera purchase and want to make sure I fully understand everything first! -Sean

To explain a little further on whether the 14-bit DXP makes a difference with the S75, it was described to me this way by a knowledgable individual: "Having a good ADC (analog to digital converter) means you can represent that larger dynamic range with finer "steps" than you would with a lower quality ADC. Typically high bit ADC's are matched with CCD's with good dynamic range. Remember, those 14 bits are at the end of the day downsampled to 8 bits to generate the JPEG/TIFF. "To answer your question a 10 bit ADC should be more than capable of doing the same job, you'd probably have to look VERY closely at a fine gradient to see any difference, and certainly downsampled to 8 bits there shouldn't be any difference." Here is a Sony chart, reproduced and enlarged to illustrate what was said above. Sony claims that their 14-bit DSP is going to produce a better image, but you will really see it in gradients and in shadowed areas. The steps should be finer, if that means anything.

All of your pics are output at 8 bits/pixel, so the 14 bits are related to internal processing. For your purposes in Photoshop, this won't really matter as you'll be dealing with either a JPEG or with a TIFF image, both of which are 8 bits/pixel. What is more important and that you want to makes sure of is that your images are well exposed, well saturated, well focused, and not overly sharpened.

I have a 1998 town and country 3.8 tranny that won't go into gear. The van stays in neutral for all gears. Everything from the internals to pump to torque converter are brand new. It was rebuilt 2 times....

If the unit has been rebuilt properly in an accredited shop then a place where a problem occurs is the installation of the box in the car. It is essential that when fitting the unit that the torque converter is fitted onto the shaft and pushed back to the box to engage the pump drive before it is offered up to the flex plate and bolted onto the engine. Once the bolts have been fixed then the torque converter can be pulled forward that bit to bolt to the flex plate. If the torque converter is bolted first and then the box offered up it is possible that the pump is not engaging correctly and not working. To check this put a pressure gauge in a line to check for oil pressure in the box when running.

2002 ford escape v6 with trans code p1744 and 741

Unfortunately, the possible issues are numerous. The problem is most likely either your torque converter, or electrical issues with your transmission. Without knowing how the vehicle is acting, if it's drivable, when it trips the codes, etc, it makes it more difficult to accurately diagnose.

Here is what ford says about those codes...

SERVICE PROCEDURE
The torque converter clutch may not engage if one or more of the following conditions exist:
- Stuck converter regulator valve
- Stuck solenoid regulator valve
- Stuck bypass clutch control valve
- Stuck pressure failsafe valve
- Pump bore ring groove depth incorrect
- Worn pump shaft or damaged pump shaft seals
- Pump shaft internal sleeve loose (rattles)
- Turbine shaft seals damaged or missing
- Incorrect Torque Converter Clutch (TCC) solenoid
- TCC solenoid mechanically stuck or electrically inoperable
- Damaged internal wiring harness
- Incorrect gear ratio (wrong sprockets)
- Damaged or worn stator support
- Worn torque converter hub bushing
- Torque converter clutch worn or damaged
Use a scan tool to monitor the following PID's:
- TCC = Commanded duty cycle for TCC solenoid
- TCCMACT = Actual slip across the TCC, measured in RPM
- RPM = Actual engine speed
- TSS_SRC = Actual turbine shaft speed
- TCCRAT = Speed/Gear ratio of torque converter/transaxle

Hope this helps.

What can I do to convert Sony DSC TX55 1080p videos to new iPad?

I have an ipad 3 and I have collections of downloaded MKV videos converted to iPad 3 compatible video formats. The program I am using is PAVTUBE Video Converter which provides presets for iPad 1, 2 and 3. The output movies play perfectly in my iPad 3. In my experience, video quality is based more on video bitrate. So please set the bitrate of output ipad video as its original value to keep TX55 video intact quality. http://www.pavtube.com/video_converter/

Why my motorola razar v3 phone can't hold any more song an it,an i cant put no more than 2 song on my phone

Hi, first, your Motorola razor V3mobile phone, has blue tooth and mp3 player facility to recieve and play song which is good. All motorola razor V3 phone has the capacity to receive song into the phone, but does not have the capacity to with hold much songs.Why?

Because all Motorola razor V3 phone does not have and external memory slot to accommodate more extra song on the phone, But it has an internal in-built memory to store data in the phone.

The input memory has the capacity to store data,like music, videos,pictures and so on, But the memory which is the "internal memory" of the phone only has a limited amount of data it can carry in it.

So that's why you can not put in too much data inside the Motorola razor V3 phones.

You can also put more some more music inside the phone by managing the internal memory of the phone by using a converter to convert the music files into smaller bit rate.

Normally music bit rate is always 128kb,but you can reduce it by converting it to small sizes of bit rate precisely 64kb or 32kb.

Warning!!, when you reduce the bit rate of a music,it might not have the same quality of sound it has before you converted it into a smaller bit rate.


Hope it helps.

Thank you for using fixya......

Cannot select a lower bit depth in colour than 24 bit?

With better processors and large storage, higher color depth is the order of the day; however if you dont want higher color depth, you can convert the images after scanning. Ofcourse it requires an addl effort.
