Abstract

The present invention relates to a best shooting moment selectable digital camera apparatus. This digital camera apparatus could decide the instantaneous best shooting moment to take photos. The technical scheme is: including camera head, memory circuit and signal processor, the signal processor includes the co-series face detecting module, eye & mouth positioning module and blink judging & mouth open judging module, meanwhile, the face detecting module reads out the digital image from memory circuit and delivers the result into eye & mouth positioning module after face positioning, the eye & mouth positioning module delivers the result into blink judging & mouth open judging module after eye and mouth positioning, the blink judging & mouth open judging module sends out the judgment result; the controlling circuit issues a shoot controlling order when the judgment result of the said blink judging & mouth open judging module means a best shooting moment.

Claims

1. A best shooting moment selectable digital camera apparatus, comprising a camera head (1) and a memory circuit (2), characterized in that:

the camera further includes;

Signal processor (3), including co-series face detecting module (3-1), eye &

mouth positioning module (3-2) and blink judging &

mouth open judging module (3-3), in which;

The face detecting module (3-1) reads out the digital image from memory circuit and delivers the result into eye &

mouth positioning module (3-2) after face positioning;

The eye &

mouth positioning module (3-2) delivers the result into blink judging &

mouth open judging module (3-3) after eye and mouth positioning;

The blink judging &

mouth open judging module (3-3) sends out the judgment result;

The controlling circuit (4) issues a shoot controlling order when the judgment result of the said blink judging &

mouth open judging module (3-3) means a best shooting moment, and doesn'"'"'t issue a shoot controlling order if the judgment result doesn'"'"'t mean a best shooting moment.

2. The best shooting moment selectable digital camera apparatus according to claim 1, characterized in that:

the said face detecting module (3-1) includes the multi-dimensioned template (3-1-1), awaiting-taken image (3-1-2) and template matching arithmetic unit (3-1-3), the template matching arithmetic unit receives the multi-dimensioned template (3-1-1) and awaiting-taken image (3-1-2) in memory (2), and delivers the arithmetic result into the face image position (3-1-4), the said multi-dimensioned template (3-1-1), awaiting-taken image (3-1-2) and face image position (3-1-4) are stored at the various address of memory (2) respectively.

3. The best shooting moment selectable digital camera apparatus according to claim 1, characterized in that:

the said eye &

mouth positioning module (3-2) includes the awaiting-taken image (3-1-2), face image position (3-1-4) and horizontal projecting &

vertical projecting unit (3-2-1), the horizontal projecting &

vertical projecting unit receives the awaiting-taken image (3-1-2) and face image position (3-1-4) in memory (2), and delivers the arithmetic result into the eye &

mouth position (3-2-2), the said awaiting-taken image (3-1-2), face image position (3-1-4) and eye &

mouth position (3-2-2) are stored at the various address of memory (2) respectively.

4. The best shooting moment selectable digital camera apparatus according to claim 1, characterized in that:

the said blink judging &

mouth open judging module (3-3) includes the awaiting-taken image (3-1-2), eye &

mouth position (3-2-2) and blink judging &

mouth open judging unit (3-3-1), the blink judging &

mouth open judging unit receives the awaiting-taken image (3-1-2) and eye &

mouth position (3-2-2) in memory (2), obtains the blink judging &

mouth open judging results for each person face and issues the order to the controlling circuit (4), the said awaiting-taken image (3-1-2) and eye &

mouth position (3-2-2) are stored at the various address of memory (2) respectively.
