LAUNCH MONITOR
First Claim
1. A method for determining a trajectory parameter of a golf ball, comprising:
- changing a mode of an image sensor to a high-speed mode, wherein the image sensor in high-speed mode has a frame rate that is faster than when the image sensor is not in high-speed mode;
capturing a first video frame of the golf ball using a first subset of pixels of the image sensor when in the high-speed mode;
capturing a second video frame of the golf ball using a second subset of pixels of the image sensor when in the high-speed mode; and
calculating the trajectory parameter of the golf ball using the first video frame and the second video frame.

Abstract
A launch monitor having a camera can be used to measure a trajectory parameter of a ball. In one example, a method can include changing a mode of the camera from a low-speed mode to a high-speed mode. The camera can include an image sensor array having a plurality of pixels. The camera can generate a video frame using more pixels in the low-speed mode than in the high-speed mode. A first video frame can be received, the video frame comprising values captured during the high-speed mode from a first subset of the plurality of pixels. A second video frame can be received, the video frame comprising values captured during the high-speed mode from a second subset of the plurality of pixels. The trajectory parameter of the ball can be calculated using the first video frame and the second video frame.

9. A computer-readable storage having instructions thereon for executing a method of calculating a trajectory parameter of a ball, the method comprising:
-
changing a mode of a camera from a low-speed mode to a high-speed mode, the camera comprising an image sensor array having a plurality of pixels, and wherein the camera generates a video frame using more pixels in the low-speed mode than in the high-speed mode so that the high-speed mode has a higher frame rate than in the low-speed mode; receiving a first video frame comprising values captured during the high-speed mode from a first subset of the plurality of pixels; receiving a second video frame comprising values captured during the high-speed mode from a second subset of the plurality of pixels; calculating the trajectory parameter of the ball using at least one of the first video frame and the second video frame. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A mobile device for monitoring a golf ball, comprising:
-
a processor; a camera comprising an image sensor including a plurality of pixels and a plurality of scan patterns for capturing a video frame, the plurality of scan patterns including a high-speed scan pattern and a low-speed scan pattern; and a computer-readable storage medium including instructions that upon execution cause the processor to; detect the golf ball in a field of view of the camera; when the golf ball is detected in the field of view of the camera, use the high-speed scan pattern so that fewer pixels are scanned per video frame than when the low-speed scan pattern is used; and calculate a motion parameter of the golf ball using one or more video frames captured by the image sensor. - View Dependent Claims (17, 18, 19, 20)
