System and method to test television device
A test system includes a computer system including a processor and a memory; and an electronic interface in communications with the computer and a television device under test, the electronic interface including a test interface board configured to permit the television device under test to be put into a debug mode by the computer system.
1. A method of testing a television device, the method comprising:
providing a television device;
displaying a white image on a display of the television device;
capturing a digital image of the white image;
determining an outline of the display using an edge detection algorithm applied to data of the digital image of the white image to determine a location of the display;
displaying a test pattern on the display, wherein the test pattern is a full-field color;
capturing a digital image of the test pattern;
masking data of the digital image of the test pattern to determine the elements of the data of the digital image of the test pattern used to analyze the test pattern:
setting an object in motion; and
detecting if a motion sensor of the television device has detected the motion.
2. The method of claim 1 , further comprising masking the data of the digital image of the white image includes:
converting red, green, and blue (RGB) pixel data into hue, saturation, and value (HSV) data,
comparing the HSV data to a predetermined threshold, disregarding HSV data that is outside of the predetermined threshold.
3. The method of claim 1 , further comprising comparing a number of bad pixels of the test pattern to a threshold number of bad pixels to determine acceptance of the television device.
4. The method of claim 1 , further comprising:
generating an audio signal by a computer;
playing the audio signal by a speaker; and
detecting the audio signal by a microphone of the television device.
5. The method of claim 1 , further comprising:
outputting an infrared (IR) signal from an IR port of the television device based on a command by a computer;
receiving the IR signal by an IR device in communications with the computer;
analyzing the IR signal by the computer.
6. The method of claim 5 , wherein the command is output from the IR device.
7. The method of claim 1 , further comprising:
commanding the television device to display a white field;
capturing a digital image of the white field at a minimum backlight level of the television device and at a maximum backlight level of the television device;
analyzing the digital image of the white field to determine if the digital image of the white field has pixels that satisfy threshold value conditions.
8. The method of claim 1 , further comprising:
commanding the television device to display a moving object in a racetrack pattern;
capturing digital images of the moving object at different locations on the television device;
determining location coordinates of the moving object for each of the captured digital images; and
analyzing the location coordinates to determine if the moving object is following an expected path.
9. The method of claim 1 , further comprising flashing a firmware image file to the television device.
10. The method of claim 1 , wherein masking the data of the digital image of the test pattern image includes:
converting red, green, and blue (RGB) pixel data into hue, saturation, and value (HSV) data,
comparing the HSV data to a predetermined threshold, disregarding HSV data that is outside of the predetermined threshold.
