Google Releases Android Camera App With Selective Focus

Google has released a standalone version of its stock camera app for Android— and it's a significant improvement on its predecessor.

The new app, called simply Google Camera, features a new user interface with revamped shooting modes, as well as the ability to selectively focus the camera.

Rumors of the new app first surfaced earlier this month after it was reported the company was testing a new camera app that would be released independently of the upcoming Android 4.4.3 update.

Google also unveiled Lens Blur, a brand new effect that enables users to shoot with a shallower depth of field to selectively focus on certain portions of a particular image. This is the first time Google has included the feature in its camera app.

"Achieving this optical effect has traditionally required a big lens and aperture, and therefore hasn’t been possible using the camera on your mobile phone or tablet," wrote Google software Engineer Carlos Hernandez in a blog post explaining how Google's research team created Lens Blur.

"Lens Blur replaces the need for a large optical system with algorithms that simulate a larger lens and aperture," he added. "Instead of capturing a single photo, you move the camera in an upward sweep to capture a whole series of frame."

The camera's panorama and portrait sphere modes have also been improved with higher resolution. Google Camera is also the first time the company has made portrait sphere, a shooting mode that that enables 360 degree panoramas, available to non-Nexus devices.

The app also features an enlarged shutter button and viewfinder, so what users see in the viewfinder will be what comes out in the shot.

Google Camera is available in the Google Play Store and is compatible with devices running Android 4.4 (KitKat).

Digital Fan Regulator Circuit Diagram

This is the project of Digital Fan Regulator Circuit diagram. The circuit presented here can be used to control the speed of fans using induction motor. The speed control is nonlinear, i.e. in steps. The current step number is displayed on a 7-segment display. Speed can be varied over a wide range because the circuit can alter the voltage applied to the fan motor from 130V to 230V RMS in a maximum of seven steps. The triac used in the final stage is fired at different angles to get different voltage outputs by applying short-dura-tion current pulses at its gate. For this pur-pose a UJT relax-ation oscillator is used that outputs sawtooth waveform. This waveform is coupled to the gate of the triac through an optocoupler (MOC3011) that has a triac driver output stage. Pedestal voltage control is used for varying the firing angle of the triac. The power supply for the relaxation oscillator is derived from the rectified mains via 10-kilo-ohm, 10W series dropping/limit-ing...

Using the SG3525 PWM Controller Explanation and Example Circuit Diagram Schematic of Push Pull Converter

PWM is used in all sorts of power control and converter circuits. Some common examples include motor control, DC-DC converters, DC-AC inverters and lamp dimmers. There are numerous PWM controllers available that make the use and application of PWM quite easy. One of the most popular of such controllers is the versatile and ubiquitous SG3525 produced by multiple manufacturers – ST Microelectronics, Fairchild Semiconductors, On Semiconductors, to name a few. SG3525 is used extensively in DC-DC converters, DC-AC inverters, home UPS systems, solar inverters, power supplies, battery chargers and numerous other applications. With proper understanding, you can soon start using SG3525 yourself in such applications or any other application really that demands PWM control. Before going on to the description and application, let’s first take a look at the block diagram and the pin layout. Pins 1 (Inverting Input) and 2 (Non Inverting Input) are the inputs to the on-board error amplifier. If you a...

Automatic Intruder Alarm Circuit Diagram

Description: This is a simple single-zone burglar alarm circuit. Its features include automatic Exit and Entry delays and a timed Bell/Siren Cut-Off. It's designed to be used with the usual types of normally-closed input devices such as - magnetic reed contacts - micro switches - foil tape - and PIRs. But it can be Easily Modified to accept normally-open triggering devices - such as pressure mats. Circuit Diagram Notes: It's easy to use. First check that the building is secure and that the green LED is lit. Then move SW1 to the "set" position. The red LED will light. You now have about 30 seconds to leave the building. When you return and open the door - the Buzzer will sound. You then have about 30 seconds to move SW1 to the "off" position. If you fail to do so - the relay will energize and the Siren will sound. While at least one of the switches in the normally-closed loop remains open - the Siren will continue to sound. However, about 15-minutes aft...
