Description

  The present invention includes a camera head on which an imaging optical system that forms subject light and an image sensor that reads the subject light to acquire image data, and a camera head that is detachably mounted, and the image data includes a predetermined image. The present invention relates to a camera system including a camera body that performs processing.

  2. Description of the Related Art Conventionally, an interchangeable lens digital camera that uses an interchangeable photographic lens mounted on a camera body in which an image sensor is built is known. In this interchangeable lens digital camera, since the subject light imaged by the photographing lens is received by an image sensor provided on the camera body side and photographed image data is generated, conventionally, a photographed image is captured on a silver salt film. The interchangeable photographic lens used in the film type single lens reflex camera for recording can be reused.

  However, for example, if a large photographic lens with excellent optical performance is mounted on a camera body with a low-resolution, small-sized image sensor, subject light is accurately imaged by the photographic lens. However, there is a problem that the subject light cannot be read with high accuracy and the performance of the photographing lens cannot be fully utilized.

  In this regard, Patent Document 1 and Patent Document 2 describe a head-exchangeable digital camera in which a camera head in which a photographing lens and an image sensor are incorporated is mounted on a camera body. According to the techniques described in Patent Document 1 and Patent Document 2, by taking a CCD suitable for the size and optical performance of the photographing lens in the camera head in advance, the photographing using the performance of the photographing lens is performed. High-quality captured images can be acquired.

  By the way, a digital camera usually has a temporary memory for temporarily recording captured image data generated by photographing a subject, and a recording loaded in the digital camera by a user for recording captured image data for storage. A medium (hereinafter, this recording medium is referred to as a storage memory) is prepared. As the temporary memory, a volatile recording medium that is superior in recording speed to the storage memory but that loses recorded data when the digital camera is turned off is generally used.

  For example, when a subject is continuously shot with a digital camera, the captured image data generated one after another is temporarily recorded in a temporary memory with a high recording speed, and the captured image data recorded in the temporary memory is sequentially stored. Read to memory. As described above, by recording the captured image data in the storage memory via the temporary memory having a high recording speed, it becomes possible to record more captured image data within a predetermined time. The number of continuous shots increases.

Here, the number of shot images that can be taken continuously at one time is the number of shot images that can be recorded in a temporary memory, and the number of shot images that can be shot with a digital camera is stored in a storage memory. This is the number of captured images that can be recorded. In an ordinary digital camera, the data size of the captured image data is calculated based on the number of pixels of the CCD mounted on the digital camera, and the number of images that can be continuously shot is calculated from the data size of the captured image data and the capacity of the temporary memory. The number of images that can be captured is calculated from the data size of the captured image data and the remaining capacity of the storage memory. The user can check the number of images that can be continuously shot and the number of images that can be shot by looking at the liquid crystal screen. If the number of images that can be shot is very small, a new storage memory can be prepared in advance.

  However, in the interchangeable head camera described in Patent Document 1 and Patent Document 2, since the photographing lens and the imaging device are provided as a set in the camera head, when the photographing lens is replaced, the imaging device is also replaced together. End up. For this reason, there is a problem that the number of pixels of the image sensor changes and the data size of the captured image data cannot be calculated, and the user cannot be notified of the number of images that can be continuously shot or the number of images that can be captured.

  In view of the above circumstances, the present invention provides a camera system in which a camera head having a built-in photographic lens and an image sensor that can notify a user of the number of images that can be continuously shot and the number of images that can be taken is detachably attached to the camera body. The purpose is to provide.

Is displayed. By checking the number of images displayed on the display screen, the user has already recorded the image data to the full capacity of the recording medium and cannot record the image data obtained by shooting on the recording medium. Can be avoided in advance.

  In the camera system of the present invention, it is preferable that the image recording unit of the camera body records image data on a portable recording medium.

  In general, image data generated by photographing a subject is recorded and stored in a portable recording medium loaded in a camera. When the image recording unit records image data on a portable recording medium, the image number calculation unit calculates the number of images of image data that can be newly recorded on the portable recording medium.

Recording on a second recording medium having a recording speed slower than the recording speed of
It is also preferable that the image number calculation unit of the camera body calculates the number of image data that can be recorded on the first recording medium.

  After the image data is once recorded on the first recording medium having a high recording speed, the image data recorded on the first recording medium is recorded on the second recording medium, so that continuous shooting can be performed. It becomes possible. In addition, the number of images of image data that can be recorded on the first recording medium is calculated by the number-of-images calculation unit, and the number of images is displayed on the display screen. It can be easily recognized.
