US 7990434 B2Abstract
a frame buffer, which sequentially stores input image data of moving images on a frame by frame basis during a shooting of the moving images;
an image correcting unit including a finite impulse response (FIR) filter which convolves with a coefficient the input image data read from the frame buffer and outputs a filtered image data;
a still image encoder, which codes the filtered image data as a still image on a frame by frame basis;
a moving image encoder for coding the filtered image data as a moving image comprised of a plurality of frames;
a display control unit, which generates an image signal by which the input image data stored in said frame buffer is displayed on a display; and
a control unit, which controls the image correcting unit, still image encoder, and moving image encoder,
wherein, in response to a still image shooting instruction signal in a time period during which a moving image based on the input image data in the frame buffer is displayed on the display, image data for one frame before it is inputted to the image correction unit is temporarily set aside and stored in an reserved area of said frame buffer, and image data of moving images being currently shot continues to be sequentially stored in said frame buffer, skipping the reserved area thereof, and
wherein in said image correction unit in which a filter coefficient for the still image encoder is set when the filtered image data is outputted to the still image encoder or another filter coefficient for the moving image encoder is set when the filtered image data is outputted to the moving image encoder, one filtering process performed by the filter on the input image data for said still image encoder is made different from that performed on the input image data for said moving image encoder, and while the input image data stored in said frame buffer is displayed on the display as a moving image, said control unit instructs said display control unit to display on the display a still image based on the image data for the one frame temporarily set aside and stored in the reserved area of said frame buffer, at a timing responsive to the still image shooting instruction signal.
2. A digital camera as recited in claim 1, wherein said image correction unit includes a storage unit which stores coefficients that determine a filtering function of the filter.
3. A digital camera as recited in claim 1, wherein said control unit controls said display control unit in a manner that the still image based on the image data for the one frame in the reserved area of the frame buffer is displayed in substitution for the moving image based on the input image data in the frame buffer.
4. A digital camera as recited in claim 1, wherein said control unit controls said display control unit to set the still image based on the image data for the one frame in the reserved area of the frame buffer to a main picture of the display and to display, in parallel, that still image and the moving image based on the input image data in the frame buffer.
5. A digital camera as recited in claim 1, wherein said control unit controls said display control unit to set the moving image based on the input image data in the frame buffer to a main picture of the display and to display, in parallel, that moving image and the still image based on the image data for the one frame in the reserved area of the frame buffer.
6. A digital camera as recited in claim 1, wherein said control unit controls said display control unit to set either the still image based on the image data for the one frame in the reserved area of the frame buffer or the moving image based on the input image data in the frame buffer to a main picture of the display and to display those still image and moving image in parallel.
7. A digital camera as recited in claim 1, wherein said control unit controls said display control unit in a manner such that the still image based on the image data for the one frame in the reserved area of the frame buffer is displayed for a predetermined period of time.
8. A digital camera as recited in claim 1, wherein said control unit sets said display control unit in a manner that permission/denial of display of the still image based on the image data for the one frame in the reserved area of the frame buffer is switchable.
9. A digital camera as recited in claim 1, wherein said control unit controls said display control unit in a manner that the still image based on the image data for the one frame in the reserved area of the frame buffer is displayed for a time duration according to a user's instruction.
10. An image processing apparatus as recited in claim 1, wherein after a coding processing by said moving image encoder has been completed, said control unit sends out the image data stored in the reserved area to said still image encoder so as to be recorded in a recording unit.
11. A digital camera as recited in claim 1, wherein a coding unit in said still image encoder and that in said moving image encoder are shared in common.
In the electronic still camera utilizing the MPEG method, it is desired that a snapshot which corresponds to one frame of the moving image can be recorded during the shooting of the moving image; for example, such a technique is disclosed in Japanese Patent Application Laid-Open No. Hei 11-75148. It is known that in this type of electronic still camera there is provided an exclusive-use memory area for use in pushing aside and storing snapshot data. However, in this type of camera, this exclusive-use memory area is not utilized until the snapshot shooting is instructed, so that the effective usage rate of the memory during the shooting of moving image is not enhanced. Making it compact-size and low-cost plays a crucial role in evaluation of merchandise values, and it is admitted that there is a room for improvement in terms of implementing area and cost performance. This is the first problem which the inventor of the present invention recognized.
