Abstract

A fast frame recorder records images of an event at a fast frame rate and plays back the images at a slower frame rate to facilitate analysis of the event. Disclosed is a solid state fast frame recorder having a solid state imager, which is selectively operable at different frame rates and having a solid state memory for storing a plurality of image frames. A programmable control system controls the memory to store temporally nonconsecutive images from the imager according to a preselected program. Both temporally nonconsecutive single image frames and bursts of temporally consecutive image frames may be stored. The number of image frames in a stored burst and the frame rate of the stored burst may be selectively varied.

Claims

1. A solid state fast frame recorder comprising:

solid state imager means for capturing an image of an event and for producing a plurality of temporally consecutive image frame signals, wherein said imager means is selectively operable at different image frame rates;

programmable control means for controlling said memory means to selectively store temporally nonconsecutive image frame signals from said plurality of temporally consecutive image frame signals produced by said imager means, in response to an external record-on-command signal.

2. The solid state fast frame recorder of claim 1 wherein said control means controls said memory means to store both temporally nonconsecutive single image frame signals and bursts of temporally consecutive image frame signals in response to said record-on-command signal.

3. The solid state fast frame recorder of claim 2 wherein said control means includes means for selectively varying the number of consecutive image frame signals in a burst which is stored by said memory means.

4. The solid state fast frame recorder of claim 1 wherein said control means controls said memory means to selectively store one or more image frame signals before and after said external record-on-command signal.

5. A solid state fast frame recorder comprising:

solid state imager means, having a plurality of photosites arranged in an array of rows and columns, for capturing an image of an event and for producing a plurality of temporally consecutive image frame signals wherein an image frame signal is produced by reading out blocks of parallel rows of photosites,

said image frame signal including sequential blocks of video information, wherein each block of video information includes parallel lines of video signals, wherein said imager means is selectively operable at different image frame rates;

solid state memory means for storing a plurality of image frame signals produced by said imager means; and

programmable control means for controlling said memory means to selectively store temporally nonconsecutive image frame signals from said plurality of temporally consecutive image frame signals produced by said imager means in response to an external record-on-command signal.

6. The solid state fast frame recorder of claim 5 wherein said control means controls said memory means to store both temporally nonconsecutive single image frame signals and bursts of temporally consecutive image frame signals in response to said record-on-command signal.

7. The solid state fast frame recorder of claim 6 wherein said control means includes means for selectively varying the number of consecutive image frame signals in a burst which is stored by said memory means.

8. The recorder of claim 7 wherein said control means includes means for selectively varying the frame rate of said burst of stored image frame signals.

9. The recorder of claim 5 wherein said control means controls said memory means to selectively store one or more image frame signals before and after said external record-on-command signal.
