Claims
- 1. An image storage device, comprising:
- addressing means for sequentially receiving image data defining pixels making up the image, and addressing the pixels as a grid of multi-pixel cells;
- first storage means for storing information concerning where in the grid cells having particular image characteristics are located;
- second storage means for storing information concerning position and nature of the particular image characteristics in the cells having the particular image characteristics;
- working memory means for storing only image data defining those pixels included in the cells having the particular image characteristics; and
- storage control means for specifying, as the image data defining the pixels making up the image is being received, those pixels whose image data is to be stored in said working memory means;
- wherein the image storage device stores only the image data defining those pixels included in the cells having the particular image characteristics, those pixels constituting less than all of the pixels making up the image.
- 2. The device as claimed in claim 1, further comprising generating means for generating addresses of the cells having the particular image characteristics for display of those pixels included in those cells by a display unit.
- 3. The device as claimed in claim 1, wherein said first storage means is adapted to communicate with a processor which processes the image data defining those pixels included in the cells having the particular image characteristics so as to obtain the information stored in said first storage means.
- 4. The device as claimed in claim 1, wherein said second storage means is adapted to communicate with a processor which processes the image data defining those pixels included in the cells having the particular image characteristics so as to obtain the information stored in said second storage means.
- 5. An image storage device, comprising:
- addressing means for sequentially receiving image data defining pixels making up the image, and addressing the pixels as a grid of multi-pixel cells;
- first storage means for storing information concerning where in the grid (a) first cells having particular image characteristics and (b) second cells neighboring the first cells are located;
- second storage means for storing information concerning position and nature of the particular image characteristics in the first cells;
- working memory means for storing only image data defining those pixels included in the first and second cells; and
- storage control means for specifying, as the image data defining the pixels making up the image is being received, those pixels whose image data is to be stored in said working memory means;
- wherein the image storage device stores only the image data defining those pixels included in the first and second cells, those pixels constituting less than all of the pixels making up the image.
- 6. The device as claimed in claim 5, further comprising generating means for generating addresses of the first and the second cells for display of those pixels included in those cells by a display unit.
- 7. The device as claimed in claim 5, wherein said first storage means is adapted to communicate with a processor which processes the image data defining those pixels included in the first and second cells so as to obtain the information stored in said first storage means.
- 8. The device as claimed in claim 5, wherein said second storage means is adapted to communicate with a processor which processes the image data defining those pixels included in the first cells so as to obtain the information stored in said second storage means.
- 9. An image processing device, comprising:
- image pick-up means for producing an image signal having image data defining pixels making up an image;
- first processor means, coupled to said image pick-up means, for processing the image signal to detect particular image characteristics, and providing trigger data indicating where in the image signal the particular image characteristics are located;
- an image storage device coupled to said first processor means and said image pick-up means, said image storage device including;
- (a) addressing means for sequentially receiving the image data defining the pixels making up the image, and addressing the pixels as a grid of multi-pixel cells;
- (b) first storage means for storing information concerning where in the grid cells having the particular image characteristics are located;
- (c) second storage means for storing information concerning position and nature of the particular image characteristics in the cells having the particular image characteristics;
- (d) working memory means for storing only image data defining those pixels included in the cells having the particular image characteristics; and
- (e) storage control means for specifying, as the image data defining the pixels making up the image is being received, on the basis of the trigger data, those pixels whose image data is to be stored in said working memory means;
- wherein said image storage device stores only the image data defining those pixels included in the cells having the particular image characteristics, those pixels constituting less than all of the pixels making up the image;
- delay means, coupled between said image pick-up device and said image storage device, for receiving the image signal and delaying it in time so that image data defining those pixels included in each of the cells is processed by said first processor means prior to the image data defining those pixels in that cell being received by said addressing means; and
- second processor means, coupled to said image storage device, for processing the image data defining those pixels included in the cells having the particular image characteristics.
- 10. An image processing device, comprising:
- image pick-up means for producing an image signal having image data defining pixels making up an image;
- first processor means, coupled to said image pick-up means, for processing the image signal to detect particular image characteristics, and providing trigger data indicating where in the image signal the particular image characteristics are located;
- an image storage device coupled to said first processor means and said image pick-up means, said image storage device including;
- (a) addressing means for sequentially receiving the image data defining the pixels making up the image, and addressing the pixels as a grid of multi-pixel cells;
- (b) first storage means for storing information concerning where in the grid (i) first cells having the particular image characteristics and (ii) second cells neighboring the first cells are located;
- (c) second storage means for storing information concerning position and nature of the particular image characteristics in the first cells;
- (d) working memory means for storing only image data pertaining to those pixels included in the first and second cells; and
- (e) storage control means for specifying, as the image data defining the pixels making up the image is being received, on the basis of the trigger data, those pixels whose image data is to be stored in said working memory means;
- wherein the image storage device stores only the image data defining those pixels included in the first and second cells, those pixels constituting less than all of the pixels making up the image;
- delay means, coupled between said image pick-up device and said image storage device, for receiving the image signal and delaying it in time so that image data defining those pixels included in each of the cells is processed by said first processor means prior to the image data defining those pixels in that cell being received by said addressing means; and
- second processor means, coupled to said image storage device, for processing the image data defining those pixels included in the cells having the particular image characteristics.
