Abstract

An image signal outputted from a CCD is converted into a digital signal by an A/D converter via a sampling hold circuit. After A/D conversion, the image data before image processing is stored in a first memory. A signal processing part performs image processing with respect to the unprocessed image data read out from the first memory in view of image property parameter data in accordance with an instruction from a CPU. The image after the image processing is displayed on a display. The user looks at the displayed image and selects, through an image property setting device, an image property parameter that the user desires, then inputs instructions such as change of parameter and adjustment. The signal processing part executes re-processing with respect to the unprocessed image data read out from the first memory, in accordance with new image property parameter data that is newly set by the user. The image property parameters are: white balance, gradation, gain, tonality, sharpness, and so forth.

Claims

1. An electronic camera, comprising:

an imaging device which converts an optical image into an analog image signal;

an A/D converter which converts the analog image signal outputted from the imaging device into a digital image signal;

an unprocessed data storing device which stores the digital image signal outputted from the A/D converter as unprocessed image data;

a signal processing device which processes the unprocessed image data read out from the unprocessed data storing device into a processed image data in accordance with an image property parameter;

an image property setting device through which an instruction is inputted to change data of the image property parameter; and

a display which displays an image represented by the processed image data processed by the signal processing device in accordance with the data of the image property parameter set with the image property setting device.

2. The electronic camera as set forth in

claim 1

, the electronic camera further comprising a recording device which records, in a record medium, the processed image data processed by the signal processing device in accordance with the data of the image property parameter set with the image property setting device.

3. The electronic camera as set forth in

claim 2

, wherein the record medium is an external record medium detachably connected to the electronic camera.

4. The electronic camera as set forth in

claim 1

, the electronic camera further comprising a recording device which records, in a record medium, the unprocessed image data and the data of the image property parameter set with the image property setting device, with associating the unprocessed image data and the data of the image property parameter with each other.

5. The electronic camera as set forth in

claim 4

, wherein the record medium is an external record medium detachably connected to the electronic camera.

6. The electronic camera as set forth in

claim 1

, wherein the unprocessed data storing device comprises an external record medium detachably connected to the electronic camera.

7. The electronic camera as set forth in

claim 1

, wherein the display displays at least one of histogram, average level, peak level, and bottom level, of the analog image signal.
