What is claimed is:
1. An image pickup apparatus for driving a moving lens in accordance with first and second command signals, comprising:
first detection means for detecting the first command signal;
second detection means for detecting the second command signal;
selection means for selecting one of the first and second command signals on the basis of output signals from said first and second detection means; and
driving means for driving said moving lens on the basis of the command signal selected by said selection means.
2. An apparatus according to claim 1, wherein said selection means selects a command signal in accordance with a predetermined algorithm.
3. An apparatus according to claim 2, further comprising setting means for setting a plurality of algorithms, and wherein said selection means selects a command signal in accordance with the set algorithm.
4. An apparatus according to claim 3, wherein said selection means includes an algorithm for giving priority to the first command signal when the first and second signals are simultaneously output.
5. An apparatus according to claim 3, wherein said selection means includes an algorithm for giving priority to the second command signal when the first and second signals are simultaneously output.
6. An apparatus according to claim 3, wherein said selection means includes an algorithm for giving priority to a command signal which is output first when the first and second signals are simultaneously output.
7. An apparatus according to claim 1, wherein each of the command signals is a focus lens command signal.
8. An apparatus according to claim 1, wherein each of the command signals is a zoom lens command signal.
The claims below are in addition to those above.
