A digital camera enabling a photographer to select representative frames reflecting his intentions, which captures both moving pictures and still images, and encodes moving picture data by frame correlation compression. The camera includes an image processing section that increases the number of I pictures in compressed moving picture data captured before, or before and after, a still image recording (SIR) instruction is received during moving picture acquisition. By this arrangement, continuous image data can be buffered for a fixed time period, and when a SIR instruction is given, this image data can be compressed and recorded as I pictures with the data being traced back for a fixed time period. As a result, image data further in the past by a fixed time period than the time at which the SIR instruction is given can be acquired as I pictures, enabling the user to select intended representative frames.
A digital camera which has the function of capturing both moving pictures and still images, and which compression-encodes moving picture data by means of a frame correlation compression system producing I pictures, P pictures and B pictures, the digital camera comprising an image processing section including a moving picture compression section which compresses P pictures, B pictures, I pictures, in the moving picture data captured before, or before and after, a time at which a still image recording instruction is given, and upon determination of a still image recording instruction, the moving picture compression section compresses the moving picture data captured to produce an increased number of I pictures in the compressed moving picture data captured in the period before, or before and after, the time at which said still image recording instruction is given, when said still image recording instruction is received during moving picture acquisition.
A digital camera enabling a user to select representative frames reflecting the user's intentions, said digital camera being adapted to capture both moving pictures and still images, and encode moving picture data by frame correlation compression, including an image processing section that produces an increased number of I pictures in compressed moving picture data captured before, or before and after, a still image recording (SIR) instruction is received during moving picture acquisition, wherein the continuous image data is buffered for a fixed time period, and when a SIR instruction is given, the buffered image data is compressed and recorded as I pictures with the data being traced back for a fixed time period so that image data further in the past by a fixed time period than the time at which the SIR instruction is given is acquired as I pictures, enabling the user to select intended representative frames.
A digital camera adapted to capture both moving pictures and still images, which compression-encodes continuous image moving picture data, after buffering it for a predetermined period of time, by a frame correlation compression system that generates Groups of Pictures (GOP) units including I pictures, P pictures and B pictures as compressed data when a still image recording instruction is not being given, and that when a still image recording instruction is given generates GOP units, for said predetermined period of time prior to the time when the still image recording instruction was given, containing an increased number of I pictures in relation to GOP units generated when said still image recording instruction is not being given, said digital camera including an image processing section processing said GOP units containing an increased number of I pictures, and including a display device receiving a processing output of the image processing section, to display still images based on said processing.
