Image pickup device, image pickup apparatus, image pickup apparatus control method and computer-readable non-transitory recording medium in which processing program is recorded

A method for controlling an image pickup apparatus, the image pickup apparatus comprising:

• an image pickup device comprising a pixel area where color image pixels are arrayed in a matrix, and each of the image pixels is divided into a plurality of focus detection pixels, and a transmission route with a plurality of lanes configured to transmit data outputted from the image pickup device, the method comprising:
• reading from the pixel area a first frame capable of constituting a color image and a second frame including phase difference information;
• performing signal processing for reducing color information of the second frame to reduce an amount of data;
• outputting both of the first frame and the second frame via the transmission route with a number of lanes that is not the smaller of a first number-of-lanes required to output the first frame and a second number-of-lanes required to output the signal-processed second frame;
• and
• stopping an operation of the transmission route for a lane that is not used for transmission of data among the plurality of lanes of the transmission route.

A computer-readable non-transitory recording medium in which a processing program for controlling an image pickup apparatus is recorded, the image pickup apparatus comprising:

• an image pickup device comprising a pixel area where color image pixels are arrayed in a matrix and each of the image pixels is divided into a plurality of focus detection pixels, and a transmission route with a plurality of lanes configured to transmit data outputted from the image pickup device;
• wherein
• the processing program is a program for causing a computer to perform:
• reading from the pixel area a first frame capable of constituting a color image and a second frame including phase difference information;
• signal processing for reducing color information of the second frame to reduce an amount of data;
• outputting both of the first frame and the second frame via the transmission route with a number of lanes that is not the smaller of a first number-of-lanes required to output the first frame and a second number-of-lanes required to output the signal-processed second frame;
• and
• stopping an operation of the transmission route for a lane that is not used for transmission of data among the plurality of lanes of the transmission route.
