1. An image pickup apparatus, comprising:
an image sensor;
an interest area setter configured to provide a signal for setting a plurality of interest areas inside an image pickup area of the image sensor, each interest area associated with an image pickup target;
a readout area setter configured to set a readout area from which an image signal is read out from the image sensor, the readout area corresponding to the set plurality of interest areas;
a memory configured to store a position of the readout area set by the readout area setter;
a readout mode setter configured to set a first readout mode and a second readout mode;
a sensor readout controller configured to control the image sensor to perform readout of all pixel signal from the image sensor in a case where the first readout mode is set by the mode setting unit, and to perform readout of a pixel signal of the readout area from the image sensor and not to perform readout of the pixel signal not associated with the readout area in a case where the second readout mode is set by the mode setting unit;
a frame signal generator configured to generate a plurality of bordering lines corresponding to a boundary of each of the set plurality of interest areas; and
an output signal generator configured to generate an output image by combining the pixel signal read out by the sensor readout controller with the plurality of bordering lines generated by the frame signal generator,
wherein the output signal generator is configured to generate the output image on which the bordering lines formed by use of a position of the readout area stored in the memory are superimposed when the image signal is read out according to the first readout mode after the readout area for the second readout mode is set by the readout area setter.
