In a high speed image capturing state, a camera signal processing circuit is not needed to perform a signal process at a high screen rate, but at a regular screen rate. In the high speed image capturing mode, raw data of 240 fps received from an image sensorare recorded on a recording devicethrough a conversion processing sectionand a recording device controlling circuit. Raw data that have been decimated and size-converted are supplied to a camera signal processing circuitthrough a pre-processing circuitand an image being captured is displayed on a display sectionwith a signal for which a camera process has been performed. In a reproducing state, raw data are read from the recording deviceat a low screen rate according to a display performance of the display sectionand the raw data that have been read are processed are processed by the pre-processing circuitand the camera signal processing circuitand a reproduced image is displayed by the display section

An optical black level control circuit comprises a digital black level adjusting circuit for generating a black level correction signal by digital processing using a given time constant when an output error between an optical black level and a reference optical black level signal is within a predetermined range so that an error becomes less than a predetermined value and an analog black level adjusting circuit for compensating for said error when said error exceeds the predetermined range.

The video camera apparatus obtains a still image sensing signal with high image quality in a progressive scan mode and is capable of recording onto a recording medium by a recording means which performs recording operation corresponding to an interlace scan mode. An image sensing signal read from a CCD image sensorin the interlace scan mode is recorded directly onto a recording medium by a recording/reproducing sectionthrough a camera signal processing circuit, while an image sensing signal read from the CCD image sensorin the progressive scan mode is converted into an interlace scan signal and is then recorded onto a recording medium by the recording/reproducing section

An imaging apparatus can obtain a high quality still picture imaging signal in the all pixels read out mode and output it by means of an output processing means adapted to the interlaced read out mode. The imaging signal read out from a CCD image sensor in the interlaced read out mode is directly supplied to a DV recording/reproducing processing section by way of a camera signal processing circuit . The imaging signal read out from said CCD image sensor in the apparatus is converted into an interlaced signal by a scan conversion section A, which is then supplied to the DV recording/reproducing processing section
