Digital camera for recording a still image while shooting a moving image
View Patent ↗In a digital camera, when snapshot shooting is instructed during recording of a moving image, a shot still image is temporarily pushed aside in a memory area for use in pushing aside ( 7 a ) in a frame buffer ( 7 ). A currently shooting motion image and a still image are displayed in parallel on a display ( 9 ), so that a user can confirm a content of a snapshot. The moving image continues to be recorded even during a push-aside operation. After a moving image processing is completed, the still image is processed by an image correcting circuit ( 4 ). The frame buffer ( 7 ) comprises a plurality of frame recording areas, and is shared on the occasions of a moving image processing and a still image processing. In a normal moving image processing, these areas are utilized in a cyclic manner, and when the still image is shot, any of areas will be utilized. Thereafter, the rest of areas are utilized in the cyclic manner for the moving images. The recording function for the moving image and still image is improved at low cost, it becomes easy to take a snapshot, and the merchandise size is not increased.
1. An image processing apparatus comprising:
an image correcting unit, including a finite impulse response (FIR) filter which convolves an input image data with a plurality of filter coefficients, which receives the input image data and outputs a filtered image data;
a still image encoder which codes the filtered image data as a still image;
a moving image encoder which codes the filtered image data as a moving image comprising a plurality of frames; and
a control unit which controls the image correcting unit, still image encoder, and moving image encoder,
wherein, the filter coefficients are changed based on whether the filtered image data is coded by the still image encoder or the moving image encoder, and
wherein, the image correcting unit is configured to selectively output the input image data as the filtered image data, keeping the input image data intact.
2. The apparatus of claim 1 , further comprising a storage unit in which the input image data for one frame is temporarily set aside in response to a still image recording instruction signal, during a coding process of the moving image,
wherein the storage unit is a memory area in a frame buffer and wherein the process for setting pushing aside the still image data is allowed until the memory area becomes full.
3. The apparatus of claim 1 , wherein
the filtered image data is provided by the FIR filter; and
when the image correcting unit is selected to output the input image data as the filtered image data, the filter coefficients are set such that the FIR filter outputs the input image data, keeping the input image data intact.
