1. A method of producing an audiovideo recording, comprising the steps of:
receiving an input video image at a portable audiovideo recording device;
converting the input video image into a digital production format by sampling the input program at a sampling frequency in excess of 18 megahertz;
providing a high-capacity digital video storage equipped with an asynchronous program recording and reproducing capability performing a frame-rate conversion; and
processing the recorded video program in the production format using the high-capacity video storage on a selective basis outputting a version of the video program having a desired frame rate and image dimensions in pixels.
2. The method of claim 1, wherein the portable audiovideo recording device is a camcorder.
3. The method of claim 1, wherein the portable audiovideo recording device is a portable communication device.
4. A portable audiovideo recording device, comprising:
an image sensor, having pixel dimensions of at least 1024\xd7576;
a graphics processor converting the input video image into a digital production format by sampling the input program at a sampling frequency in excess of 18 megahertz;
a high-capacity digital video storage equipped with an asynchronous program recording and reproducing capability and performing a frame-rate conversion; and
output circuitry processing the recorded video program in the production format using the high-capacity video storage on a selective basis to output a version of the video program having a desired frame rate and image dimensions in pixels.
5. The device of claim 4, wherein the portable audiovideo recording device is a camcorder.
6. The device of claim 4, wherein the portable audiovideo recording device is a portable communication device.
The claims below are in addition to those above.
All refrences to claims which appear below refer to the numbering after this setence.
1. An image reading apparatus comprising:
a reading unit including a movable sensor;
a first reading mechanism which moves said reading unit to read an original placed on a platen;
a second reading mechanism which conveys the original relative to said reading unit to read the original;
a common driving source which drives said first reading mechanism and said second reading mechanism;
a transfer unit which transfers a driving force from said driving source to said first reading mechanism and said second reading mechanism; and
a switching unit which switches rotation used to drive said second reading mechanism to one of forward rotation and reverse rotation with respect to rotation of said driving source in one direction, said switching unit operating as said reading unit moves.
2. The apparatus according to claim 1, wherein said switching unit operates in accordance with a moving amount and a moving direction of said reading unit.
3. The apparatus according to claim 1, further comprising a recognition unit switched by said switching unit, said recognition unit being read by said reading unit to identify the forward rotation and the reverse rotation of said second reading mechanism.
4. The apparatus according to claim 3, wherein said recognition unit is disposed between a position where said reading unit operates said switching unit, and a position of said reading unit when the original is conveyed and read.
5. The apparatus according to claim 1, wherein a reference plate configured to correct a position of said reading unit in a moving direction, or perform color correction in processing a read image is disposed between a position of said reading unit when said reading unit is moved to read the original, and a position of said reading unit when the original is conveyed and read.
