An object of this invention is to provide an image sensing apparatus which shortens the photographing interval in single shooting and sequential shooting. To achieve this object, an image signal corresponding to an object image is read from an image sensing element to output image data by the processes of a signal processing circuit and A/D converter. An image processing circuit integrates the image data output from the image sensing element for white balance processing. An image display circuit performs processing of displaying on a display an object image during imaging on the image sensing element. A system controller so controls as to cause the image processing circuit to perform integral processing of the image data for the white balance during read of an image signal from the image sensing element, and cause the display to display the object image after integral processing ends.

Image sensing apparatus

An image sensing apparatus comprises an image sensor that performs image sensing in response to an inputted image sensing instruction, a recording medium that stores a sensed image, and a controller that controls to record on the recording medium the sensed image in a first format instead of a second format, different from the first format, which is designated in advance when a format change instruction is designated by a user within a predetermined period after sensing the image.

A recording system comprises a non-volatile recording medium, a recording device for recording information data on the recording medium, the recording medium including a first recording area in which to record the information data, a second recording area in which to record data indicative of an erased area in the first recording area, and a third recording area in which to record data indicative of a use status of each area in the first recording area. The recording device is operative to detect from the recording medium the data recorded in the second area and the data recorded in the third recording area, and perform erasure of, and recording of the information data in, a recording-enable and unerased area in the first recording area. A data processing apparatus comprises a detector for detecting whether a non-volatile recording medium has been attached and an erasing device for erasing information data from a predetermined area of the recording medium, less than the entire recording area, according to an output of said detecting means.

When a device is removed during recording, there is a possibility such that a fatal error may be caused in the device. Information for device control is read out from the device. When it is detected that a cover which covers the device is opened or that a power voltage is equal to or less than a predetermined value during the operation with a battery, a control unit invalidates the read-out control information for the device. Therefore, when the device is erroneously taken out during the recording or when a battery output drops during the recording, a fatal error is not caused in the device.

Data recording apparatus and method including control data invalidating function

An image processing apparatus, for an image recording and reproducing system, comprises a means for writing a given field image signal in a field memory, and a means for reading out the field image signal written in the field memory. The reading means reads out individual lines in sequence in a first field of the field image signal and also reads out a plurality of lines in a second field of the field image signal concurrently.

Image processing apparatus

An image pickup apparatus is provided which can obtain a high image quality by using a camera with a conventional field read type DSP. The image pickup apparatus has an image pickup element having a plurality of color filters disposed in a predetermined layout at respective pixel positions, a calculating and processing unit for performing calculation and processing by using two sets of adjacent pixel data in the vertical direction, at each line of image data generated by the image pickup element, and a luminance signal generating unit for generating a luminance signal by using an output of the calculating and processing unit.

A recording apparatus for recording identification data of a predetermined number of digits for identifying recording data on a recording medium together with the recording data, including a display unit having a display capacity of a number of digits less than the predetermined number of digits for indicating the identification data, and an operation switch unit. Information Identification data to be displayed on the display unit is circularly designated, and the identification data is set and changed. A reproducing apparatus includes a reproducing unit for reproducing an image signal recorded together with an ID signal representing an attribute at each access position of a medium, a display unit capable of displaying characters or numerals, and a control unit for causing the display unit to display an access position of the reproducing unit upon access of the reproducing unit, and causing the display unit to display the ID signal when a predetermined designation is made.

Recording and/or reproducing apparatus displaying identification information

The invention provides an image signal processing apparatus for processing an image signal. When an image signal is supplied and the input image signal is stored onto a memory medium and the image signal stored on the memory medium is generated, only the image signal generated from the memory medium in the image signal stored on the memory medium can be erased, so that the image signal can be stored by a simple construction without erroneously erasing the image signal stored on the memory medium.

Image signal processing apparatus having an erasing function

A video signal recording apparatus includes a first memory arranged to store an image signal and a second memory arranged to store an image signal outputted from the first memory. These memories are controlled in such a manner that, if a new image signal is inputted to the first memory while the second memory is still in process of storing the image signal outputted from the first memory, a storing action of the second memory is suspended, so the new image signal can be stored in the first memory even while the second memory is in process of storing the image signal.

There is provided an erasing device for erasing the recorded signal in each recording block on a recording medium such as a still video floppy which can individually record the signal into each of the recording blocks. The erasing device comprises: a discriminating circuit to discriminate a recording state of each recording block; an erasing circuit to generate an erasing signal; and a controller to control the erasing circuit in accordance with the result of the discrimination of the discrimination circuit. With this device, a state in which the memory area on the medium is erased can be obtained in a short time using little energy.

An image processing apparatus adds a plurality of input digital chroma image data and input digital luminance image data during a back porch of the input image data and outputs average value data. A subtractor subtracts the average value data, from the input digital chroma image data and input digital luminance image data and outputs data, using a first subtracting method for the chroma image data and a second subtracting method, different from the first subtracting method, for the luminance image data. A memory stores the data output by the subtractor. The input digital chroma image data and the input digital luminance image data are sampled at a frequency an integral number of times as great as a frequency of a subcarrier, and are added.

An image signal processing device having a frame memory which includes a first-field storage area for storing a first-field image signal and a second-field storage area for storing a second-field image signal and is capable of storing an image signal for one frame is arranged to cause the frame memory to store the image signal for one frame by every field in separate storage areas, and, after that, in reading out the second-field image signal included in the image signal for one frame stored in the frame memory, to temporarily store in the first-field storage area the second-field image signal which has been stored in the second-field storage area, and then read out the second-field image signal. This arrangement enables the device to efficiently use the memory and to stably output the image signal without any image turbulence. The arrangement thus enhances the operability of the device.
