An image capture apparatus includes an image capture unit, a recording unit, a wireless communication unit and a control unit. The recording unit records digital image captured by the image capture unit on a recording medium. The wireless communication unit transmits the digital image recorded on the recording medium to an external recording apparatus. The control unit determines, using additional information corresponding to the digital image recorded on the recording medium, whether or not the digital image recorded on the recording medium is already transmitted to the external recording apparatus. The additional information is received from the external recording apparatus. The control unit controls the wireless communication unit to transmit the digital image recorded on the recording medium to the external recording apparatus if the control unit determines that the digital image recorded on the recording medium is not already transmitted to the external recording apparatus.

In an image capture apparatus, the data rate of image data output from the image capture device is changed by calculating a first data rate of the image data according to a first size of a variable display area that displays the image data. Information indicating the calculated first data rate is sent to the image capture apparatus. The size of the variable display area is changed to a second size responsive to a user command and a second data rate of the image data is calculated according to the second size. Information indicating the calculated second data rate is sent to image capture device.

Camera apparatus and image processing system with variable resolution

An image processing apparatus for reducing image deterioration caused by a saturated area of an image signal obtained from an image sensor. Specifically, an image signal output from a CCD has a saturated portion that is detected by a saturation detector and has red, green and blue signals separated from it by a color separation unit. Prescribed processing is then applied to obtain color difference signals. A signal indicative of the saturated portion is stored in a FIFO memory and is subsequently read out. A control signal generator then generates a control signal with a prescribed waveform at the periphery of the saturated portion, and the control signal is also stored in a memory. The control signal is then read out of the memory and applied to a suppression signal generator, which outputs a suppression signal. Finally, a suppression circuit suppresses the color difference signals in conformity with the prescribed waveform.
