Claims
- 1. A still camera comprising:
- photographing means for photographing a photographed object and outputting image data:
- means for converting a voice to an electric signal and outputting the converted electric signal as a voice data;
- an image data and voice data coding means connected to said photographing means and said converting means for coding the image data and the voice data in a time division manner and including a quantizing section and at least one coding section through which both of the image data and the voice data are processed in the time division manner, wherein said image data and voice data coding means comprises a forward discrete cosine transformation section, a quantizing table for controlling said quantizing section, said quantizing section being connected to said forward discrete cosine transformation section and said quantizing table, a differential pulse code modulation section connected to said quantizing section, a run length coding section connected to said quantizing section, and a Huffman coding section connected to said differential pulse code modulation section and said run length coding section;
- image data recording means connected to said image data and voice data coding means for recording the coded image data to a recording medium; and
- voice data recording means connected to said image data and voice data coding means for recording the coded voice data to the recording medium.
- 2. A still camera according to claim 1, wherein the quantizing section of said image data and voice data coding means performs a discrete cosine transformation and a weight of each of frequency bands of a quantizing table can be changed in accordance with an externally set voice mode.
- 3. A still camera according to claim 1, wherein unit voice data can be recorded to a header portion of a still picture image file in said recording medium.
- 4. A still camera comprising:
- photographing means for photographing a photographed object and outputting image data;
- means for converting a voice to an electric signal and outputting the converted electric signal as a voice data;
- an image data and voice data coding means connected to said photographing means and said converting means for coding the image data and the voice data in a time division manner and including a quantizing section and at least one coding section through which both of the image data and the voice data are processed in the time division manner, wherein said image data and voice data coding means comprises a forward discrete cosine transformation section, a quantizing table for controlling said quantizing section, said quantizing section being connected to said forward discrete cosine transformation section and said quantizing table, a differential pulse code modulation section connected to said quantizing section, a run length coding section connected to said quantizing section, and a Huffman coding section connected to said differential pulse code modulation section and said run length coding section;
- image data recording means connected to said image data and voice data coding means for recording the coded image data to a recording medium; and
- voice data recording means connected to said image data and voice data coding means for recording the coded voice data to the recording medium,
- said image data and voice data coding means coding the image data for an effective image data period and coding the voice data for a vertical or horizontal blanking period.
- 5. A still camera according to claim 4, wherein said image data and voice data coding means has a memory for storing the voice data before coding for the effective image data period.
- 6. A still camera according to claim 4, wherein an interrupt signal relative to a completion of coding processing of effective image data is outputted from said image data and voice data coding means to a central processing means.
- 7. A still camera according to claim 4, wherein said image data and voice data coding means makes a quantizing table by scaling and calculating a basic quantizing table using a scale factor, and a central processing means can read the quantizing table.
- 8. A still camera according to claim 4, wherein a sampling frequency of the voice in the converting means for converting the voice to an electric signal is set to an integer multiple of a frame frequency or a field frequency of an image.
