Abstract

An image capture system comprises an image input and processing unit. The image input obtains image information which is then passed to the processing unit. The processing unit is coupled to the image input for determining image metrics on the image information. The processing unit initiates a capture sequence when the image metrics meet a predetermined condition. The capture sequence may store one or more images, or it may indicate that one or more images have been detected. In one embodiment, the image input is a CMOS or CCD sensor.

Claims

1. A computer system, comprising:

a memory;

an image sensor to capture a first image; and

a storage medium containing instructions that cause the processor to;

read one or more image characteristics of the first image to determine one or more image metrics;

access an image profile programmed via an interface and not received through said image sensor, the image profile defining one or more image threshold values;

compare the image profile with the image metrics to determine whether the image metrics are above or below one or more of the threshold values;

determine that the image profile identifies the first image if the image metrics are above or below one or more of the threshold values; and

request to store a representation of the first image into the memory in response to determining that the image profile identifies the first image.

2. The system of claim 1, wherein the image sensor comprises a complementary metal oxide semiconductor sensor.

3. The system of claim 1, wherein the first image comprises colors red, green, and blue and luminosity.

4. The system of claim 1, wherein the first image comprises colorimetric data.

5. The system of claim 1, wherein the first image comprises photometric data.

6. The system of claim 1, wherein the first image comprises an image from a complementary metal oxide semiconductor (CMOS) sensor.

7. The system of claim 1, wherein the first image comprises an image from a video.

8. The system of claim 1, wherein the image profile comprises one or more thresholds for a rate of change of color.

9. The system of claim 1, wherein the image profile comprises one or more thresholds for a rate of change of luminosity.

10. The system of claim 1, wherein to determine the one or more image metrics, the processor is to perform motion detection.

11. The system of claim 1, wherein to determine the one or more image metrics, the processor is to monitor for an increase in detected motion.

12. The system of claim 1, wherein to determine the one or more image metrics, the processor is to determine a change from a first level of motion to a second level of motion.
