Digital image capturing method and apparatus

摘要

A method and an apparatus are provided for capturing a moving image and a still image. Moving-image capturing is ceased, when a still image-capturing request is generated. Still-image capturing operation parameters are set in the image sensor. The image sensor is exposed to generate still-image data. Moving-image capturing operation parameters are set in the image sensor, when generation of the still-image data is complete. The image sensor is exposed to generate the moving-image data. The still-image data is quality-processed and compressed to generate still-image frame data. Moving-image frame data generated by quality-processing and size-adjusting the moving-image data are connected and compressed to generate a moving-image stream. Quality-processed virtual moving-image frame data is generated using the still-image data. The quality-processed virtual moving-image frame data is inserted into a loss section of the moving-image stream corresponding to a period in which the moving-image capturing is ceased.

1. A method for capturing a moving image and a still image by a digital image capturing apparatus, the method comprising the steps of:
setting still-image capturing operation parameters in an image sensor to establish a still-image capturing mode, when a still image-capturing request is generated during a moving-image capturing mode; exposing the image sensor according to a full-pixel scheme for the still-image capturing to generate still-image data when the still-image capturing mode is established; setting moving-image capturing operation parameters in the image sensor to re-establish the moving-image capturing mode, when generation of the still-image data is complete; exposing the image sensor according to a partial-pixel scheme for the moving-image capturing to generate the moving-image data and resume the moving-image capturing, when the moving-image capturing mode is established, wherein the partial-pixel scheme uses a sub-sampling scheme that includes using image sensor values of partial pixels at predetermined positions among full pixels of the image sensor; generating still-image frame data corresponding to the still-image capturing and a moving-image stream corresponding to adjusting the moving-image data; generating virtual moving-image frame data having a same view angle and a same number of pixels as the moving-image frame data by using the still-image frame data; and inserting the virtual moving-image frame data into a loss section of the moving-image stream corresponding to a period in which the moving-image capturing is ceased for the still-image capturing when the loss section is longer than a time corresponding to the virtual moving-image frame data.
